Styrofoam is very finely-celled so it sands very well without crumbling .. using a sanding block it’s possible to get smooth, sharp-edged shapes fairly easily. Styrofoam may be familiar as the light blue sheets (although styrofoam comes in other colours according to different grades or densities) made for wall insulation and commonly used in theatre and film workshops as a rapid carving material. These foams are very easy to cut with a knife (or hot wire cutter, except PU foam) and both styrofoam and PU foam can be sanded effortlessly to a smooth, sharp finish even for very small forms. Strong PVA glue (always better to use the ‘wood glue’ type rather than the economy-style ‘school’ glue) will bond foam-to-card well but not instantly, so joints often have to be temporarily taped together with masking tape while setting. It also helps if this card doesn’t fragment (divide into layers) so easily when finely cut. The fuzzy burr of paper which develops along both sides can be removed by carefully ‘scuffing’ with the sanding block at a 45degree angle. Extra care needs to be taken while working with foamboard not to press down too firmly while steadying the sheet as finger-dents are very easy to get. Also, whatever you decide to cut with should be held as horizontally as possible. Avoid … It may also help to say that the scalpel blade is ‘meant to’ bend a little with the pressure of being pushed against the ruler and that if it doesn’t its always liable to wander. However, it is clean and neat .. in other words the making of it looks cared about. An alternative when working with these plastics (also generally a much cleaner one) is to use a plastic solvent such as ‘Plastic Weld’. Take the second piece of foam and place it on top of the first with the glue and using some long pieces of wood clamp down the two sides of the foam with clamps. It is therefore quite literally a three-dimensional ‘blueprint’ of the intended design. If you are in a hurry and do not care about the details, you can cut with the first thing you grab. These are then cut out and assembled to form 3D structures. The ‘rule’ is that anything which has a significant physical bearing on the set space (such as a pillar, steps, changes in floor level, opening doors, railings etc.) Then extend the blade out and make a second cut which slices the rest of the board. To solve this little mental problem we have to go back to ‘1:25 to 1:50’ and look at what we might have done. If we divide 25 into 50 we get ‘2’ .. if we then divide 2 into 100 we get ’50’. Foam board is a sturdy and lightweight material that is easy to cut with a sharp craft knife or with a picture framing mat cutter. This would then need to be made detachable. One possible way of solving this is by cutting just half way through on one side, taking the line carefully round (i.e. Strictly speaking if the walls of a studio set are going to be built to a certain height, even if that extends beyond what the camera will see, they should be built to that height in the model. Even in the simpler case of practical doors it may be better just to glue them ajar to show that they’re practical. The same is true generally of ‘greyboard’ or recycled grey or brown cardboard which is hard and full of gritty particles. If it needs to be a perfect curve, a stencil or some other guide is the best way to draw it. A rubber contact adhesive such as ‘Evo-Stik Impact’ will be needed. If the set design has been conceived and developed largely on the drawing board it may be only at the ‘white card model’ stage that this is even considered! If gluing becomes necessary i.e. It is usually not a realistic, atmospheric rendition of what the set will look like, let alone how it will appear in the film. It is a common mistake to forget that something will be seen through a window, or an open door. Step 6 Knowing just how to cut foam board and still have the edges look nice can be a tricky thing. They feature coarse 100 grit on one side and medium 180 grit on the other to quickly and easily file nails to desired shape, giving edges a flawless finish. A good online source for ordering/delivery is Bay Plastics www.plasticstockist.com (the 1-2mm white foamed Pvc included in the online catalogue is the cheaper ‘Palfoam’ rather than Palight).  Most of the softer forms, such as the standard Daler-Rowney mountboard sold in A1 size sheets are fine for perhaps most of the work ..walls or simple cut-outs.. but unsuitable for more delicate structures such as railings for example, because they are too thick in scale and will break apart if cut too thin. Perhaps an even easier alternative for achieving curving walls is to use a dense foam sheet such as Plastazote, which is spongy and very flexible, or a thin styrene plastic (see below). Keep your movement smooth from top to bottom and try to not vary the depth of your knife at all while you are cutting. I have to say that I have mixed feelings about the use of foamboard for these models. But, nearer to home perhaps, some regular foamboards are made with a polyurethane core rather than polystyrene and the paper coverings are easy to peel off cleanly to use the smooth foam as a constructional or shaping material. Polyisocyanurate foam board is rigid foam used for insulation. the same should apply to the white card model. I put a piece of duct tape on the back of the cut to reinforce it. One should usually allow at least 15 minutes for this. This is made only in white and will be most familiar as hardware packaging material and ceiling tiles etc. White foamboard is one of the most common materials used as a structural basis for 4. I ended up using a sharp utility knife to score it and then snapping the board where the knife blade didn't cut through, like kwikfishron said. with a try square) to the other side and completing the cut in exactly the same place on this side. The thinnest gauge (1mm) is ideal for delicate cut-outs such as windows and railings. Since the white card model is commonly a pasted, 3D version of the technical drawings  one would assume that these dictate the scale of it .. but this is only partly true. This is yet another solid argument for starting the physical model process early on, if only as rough ‘sketch’ version. The designer may build a version earlier in the design process to test the design’s three-dimensionality ( to check general proportions, to better visualise filming possibilities etc.) Foam board can sometimes be referred to as foamcore but, no matter which name you call it by, you might know from experience that the edges love to get jagged when you try to cut it. Just make a … Bend your Styrofoam piece if you require a curved shape for your project. Especially if two larger pieces are being laminated (i.e. To double the dimensions you need to choose the next size up, i.e. The ‘white card model’ of the present context is, in many ways, anything but rough and inexact and most often, due to its usual place in the chronology of design steps, it is no longer exploratory. Hogwarts was a very clever, highly complex and meticulously planned creation which brought together CGI, real locations, realistic physical models and full-size builds. Take a few wooden dowels or pieces of wood in the size curve you need, and fit the Styrofoam piece around them. often misunderstood) when it comes to the white card model. I maintain an up-to-date record of the best or most convenient places to get these special materials in Updated sources/prices of specific materials which can be found in the Suppliers section. These may well become inevitable with a ‘working’, much-carried cardboard model, but just a little bit of extra strengthening can limit the damage. In any case models in a larger scale i.e.1:25 simply become too big to be manageable. Common types of card can be used, with the drawings spraymounted to them. Draw the desired shape with a marker on the foam board. Even if one has recently completed the technical drawings, before starting a 1:50 or a quarter-inch white card model .. or any scaled model .. one should take a moment to re-acquaint oneself properly with the scale again. Some brands of this type of foam glue very readily with superglue. An alternate source for this type of foam is poster board found at most department stores. Coating any foam edges first with slightly diluted PVA will solve this and when dry, UHU or sprays can be used on these edges, but it is rather laborious to go to this trouble. This form of model-making is, I think, still proving itself invaluable despite increasing competition from the likes of SketchUp. Cutting a curve starts with accurately drawing the line you want to cut out. First, they dry-fit each board into place, measuring and marking where to place the 22-degree lap cut that will cleanly meld it to adjoining trim, the square cut that will butt it against a door frame, or the 45-degree-angle that will fit it into a corner. The thicker the foamboard the more pronounced this can become. Foam board insulation is a relatively inexpensive type of insulation that adds a high R-Value to areas where adding standard installation is either cost-prohibitive or not required. Expanded polystyrene is basically the same substance but formed differently and the cells are much larger. Score the outline with a small craft knife. Type above and press Enter to search. A third alternative (but only if gluing acetate to another plastic such as styrene) is the thin plastic solvent available for melt-gluing a range of plastics (e.g. If you’re lucky, slight changes in level are easy to achieve just by layering different thicknesses of card on top of the baseboard. An effective and often easier alternative however is to draw these structures with permanent ink on acetate sheet (but the acetate should ideally be matted to differentiate it from glazing). On the one hand a good, robust, polyurethane-core foamboard is invaluable as a lightweight baseboard .. but if a cheap polystyrene-core one is used it is liable to warp badly over time and ends up showing every finger impression! These are quite strong, but also suitable for delicate cutting. There is never any advantage in being able to cut right through in one go even if that is relatively easy. Another example of the illustrative quality of white card models from Edwina Camm, also showing the importance of including the ceiling in this context. Such experimentation can directly pool into what I call our general ‘creative matrix’ as designers. Unfortunately the UHU tube nozzle, the consistency of the glue and the way it comes out, are not designed for really precise control .. such as is needed when trying to apply the glue to a thin edge of card for example. It is usually made once the design has been finalised, most often incorporating the detailed technical drawings created for the construction of the set. The ground level (at least the visible set floor) should also be represented in white rather than bare wood if this is used. secure enough to be a good support, not only when transporting the model but also for resting it down even where there are no totally free table-tops available. The 300gsm is roughly 0.5mm thick and the 600gsm 1mm thick. Just cut enough to be able to bend it backward. However if the foamboard is warped (and the cheaper polystyrene core foamboards often are) this must be first corrected by firm bracing on the underside. When the ceiling becomes a feature of the design it should definitely be included, but again detachable. with a 24 gram blue wonder and a 800 mAh LiPO. To cut foam board straight, start by making sure you measure and mark a straight line. The best advice I can give (apart from the points above) is to spend a little time getting acquainted just with what it feels like to press the scalpel blade firmly against a metal edge and move along evenly. Be sure to select boards with fairly straight grain and no knots so they can bend without breaking. There now follows a short list of the most significant individual points worth noting: The base on which the model is mounted should be flat and stable i.e. the underside to make it so) and positioned so that the main light source is falling into the cutting edge, so that the marked line is not obscured by shadow. Towel Ring Height and Other Fixtures: Proper Measurements, Homemade Paint Removers for Every Surface. Windows which are meant to be seen through (or any transparent surfaces) need to allow just that in the model, and need to be cut out, and also surfaced on the back with thin acetate to make it clear if they are going to be glazed (this for example is something both the lighting and sound crews will need to consider). It is more solid in the center, which is why it is sometimes referred to as rigid foam insulation. Interesting process for easily getting a beautifully curved shield. Another form of glue which styrofoam seems to accept is spraymount, especially effective if sprayed lightly on both surfaces like a contact adhesive. Foam board insulation is often used in garages, work sheds, or other spaces that may not require interior finish or wall trim. The best way to keep foamcore from curling is to frame it, but if this is not practical, there are a couple of alternative methods. Above is an illustrative ‘sample’ of white card model, simply made to convey a few of the typical things mentioned above .. and not outwardly expressing any aesthetic! As a general rule when cutting anything by hand with a knife it is always better to take things carefully and slowly. Matte is definitely better to choose (there are some semi-glossy types), and avoid white card which has a noticeable layering inside (a bit like plywood) because this is likely to be the toughest to cut! If you’re unlucky and part of the floor sinks below the common ‘0’ level, this is another good reason for using something like 10mm Kapa-line foamboard as a base. And a terrific companion to my Roman Gladius sword project. Then, clamp the rigid board to a flat surface with rubber clamps so it's held still and you can cut it … One should, for example, look at how small a figure is (average male actor 1.75m high), how high a door might be (average 2m high), but just as importantly how thick a piece of card is needed to represent 5 or 10cm reasonably accurately. I’m going to answer all of the questions I had when I started researching so I hope this isn’t a beat down of info. If you do a large amount of foam board cutting regularly, you could also consider investing in a foam cutting saw. This type of card is also known as ‘oiled manilla’ and is meant for making very fine-cut stencil shapes. The manilla card has been impregnated with linseed oil which prevents it from fraying or breaking so easily. The scale 1:20 is a ‘larger’ scale than 1:25 but many people also get confused because, from the way it is written, it appears a smaller value. these models, together with the thinner mountboard. Products provide superior insulating properties; R-value (5- in. Even at the later stages of design development it pays to be truly creative with the model, to be inventive with methods of representation or ‘simulation’. This is the normal size sheet (20 inches by 30 inches and 5mm thick). A kitchen knife or a pocket knife can work well if it is sharp enough and if you have a grindstone or file to keep them sharp as you cut. The best option is undoubtedly a utility knife with an X-Acto knife being a close second. Digital insertion via blue or green screen, or even old-style back projection, may solve a number of problems .. but these also should be planned for earlier in the design process. Bending Generally 5mm foamboard will suffice for an A2 size model and 10mm foamboard for A1 and is often a better option than choosing heavier plywood or MDF! Neither a scalpel nor Stanley knife will go very deep so often a sharp penknife, fruit knife or serrated bread knife will serve better. The material may also be familiar from exercise or camping mats. Although very soft it can be cut quite cleanly with a sharp scalpel though it can’t be sanded. A dull blade will make it impossible to cut without getting jagged edges since the tiniest variance in the blade can affect it. Save my name, email, and website in this browser for the next time I comment. One can’t mark on acetate with a normal pencil so either the shape to be cut needs to be drawn on paper and used as a template underneath or the surface covered with masking tape and lines marked out on that. Usually the minimum quantity one can order is an 8x4ft sheet (1220x2440mm) which can be quickly delivered, but if one accepts this the price of 1mm or 2mm Palight can work out cheaper than most forms of cardboard. Acetate cuts easily with a scalpel but if need be thicker sheets can be scored and snapped cleanly. Cutting Creating curved shapes with foam board. For starters, it has one side that has ridges or bumps on one side of it, the other side being flat and smooth like a regular foam board. More about what’s achievable with oiled manilla can be found in Working with stencil card which is under ‘constructing’ in the Materials section. It gives an overview for the technical crew responsible for building and furnishing a set (or modifying an existing one) of how much work is required. But the elevations (meaning the vertical faces of walls, structures etc.) As I’ve said 1:50 (or 1:48) is the most practical scale and the master ground-plans are often drawn in this scale. This may directly reflect how the set will be built for filming in which case the so-called ‘floating’ walls will be indicated on the groundplan. This may not always be visible or matter, but better right-angled edges are needed when gluing two pieces together to make a corner. To make the boards even more pliable, we soaked them in hot water in a 10-ft. aluminum gutter. The material needs to be cut half-way through in repeated parallel lines (as little as 2mm apart for a tight curve), making it more flexible. Practicals (i.e. Bending Whether curved walls need to be made in either foamboard or mountboard the method is similar. I’ve written elsewhere that I don’t consider pure white card to be the right medium at all when it comes to representing, or even just mocking up spaces. Although foamed Pvc sheet is not so easily obtainable (at least not from art shops) it has excellent properties, being somewhat easier to cut than even some forms of card while remaining much more durable and resistant to warping. A popular option is to use a fine toothed hand saw. Plug in a small wire cutter until the wire is hot. don’t necessarily need to be permanent, these light, easily-worked, so-called ‘rigid’ foams may be an option. Cutting It is important to make the distinction right now between the ‘white card model’ meant in this case and the other case .. the exploratory, often rough and inexact, sometimes coloured, ‘sketch’ model which is often referred to by the same name, especially in the theatre. Styrofoam, expanded polystyrene and PU foam. Foam boards are also known as foam core boards, the terms are usually interchangeable. If slender structures just as stair balusters or metal railings (although spatially flat) are left as blocked-in drawings they can create a false impression of space and often completely obscure the effect of the stairs. There’s nothing that transmits an impression of carelessness more than a lot of bashed corners! In cases like this the simpler shortcut would be to make the model with the blinds open and make separate inserts to convey the effect of them down if this is necessary. and it maidened at 10 oz. The walls can be surfaced with paper to hide the grooves, but the curve must be secured (in the right curve) before this is done (if done before it will stop it from bending) and it’s better to use permanent spraymount otherwise a thin paper covering will buckle badly. Next to clamp the middle of the blank use two pieces of wood and place them on the top and bottom of the blank. Make a Roman Scutum . cleaner cut is almost always achieved by starting carefully with a very light guiding cut and following through a few times, increasing the pressure gradually. Gluing You should cut this kind of foam board with the ridges on the bottom. Recently though the 4D modelshop in London have started stocking 1mm and 2mm Palight in small (300x600mm) pieces, ideal if you just want to try out a small amount first. Doing so will make sure that the knife can reach all the way through at the angle you are cutting at with length to spare. This rigid foam layer needs a minimum R-value of R-5, and that's impossible with 1/2 inch of foam. This can be visually confusing. .. in how one renders one’s own technical drawings (better still if it actually enhances rather than detracts from the communicative clarity of them!) Other methods include .. if the superior Kapa-line foamboard is used, the paper layer can be peeled off (either from one or both sides) making it much more bendable without having to score the surface. In the case of the materials and techniques recommended, it is really just an overview of possibilities and doesn’t go into full, step-by-step instruction on how to build. An alternative ‘trick’ is to insert a few short lengths of double-sided tape along an edge to be glued so that these hold the card pieces temporarily but firmly together while the slower glue (alternating in between) is taking effect. At an appropriate thickness it can be ideal for curving walls for example, or even for building up a run of curving steps. 5mm at 1:50 scale represents 25cm). However, what if the elevations have been drawn in 1:20 scale and need to become 1:50? Any excess solvent outside the joint quickly evaporates resulting in a very clean joint. Cartwright has published several eBooks on craft and garden-related subjects. It will resist the solvents in glues and spray-paints, though these will still work well to bond or cover it. Rigid PU foam is mainly available from suppliers of resins and fibreglass materials. But the grooves only work for bending one way, so for example an ‘s’ curved wall has to be grooved in alternate positions on both sides for it to bend properly into an ‘s’. The rough edge produced can easily be sanded smooth with coarse sandpaper on a sanding block. ‘Plastic Weld’ or ‘Extrufix’) which has to be brushed onto a joint from outside. The nose and tail ends were tapered using pleats to make the tube’s diameter smaller and result in a slight compound curve. but these things have usually all been worked out by the final stage and here the model made is more of a communicative device than a ‘testing’ tool. I wouldn’t say that elements of colour are totally ‘banned’, but particularly here it is important not to upset the overall balance.

In my experience, as long as the essential proportions are right this figure should be as simply conveyed as possible and flat cut-out figures often look better in this context than 3D ones. Measure for your width. There should be a unity .. or rather, the word is homogeneity .. of colour and treatment throughout the model. But it should show very clearly where the floor is ‘the set’ and where it is not, so sometimes it makes sense for the ‘offstage’ to be differently coloured. Polyurethane foam .. often referred to as ‘PU foam’ .. is usually found in white or beige, and is often a harder, denser rigid sheet foam than the others.
