# 1) 3D houses 2) curved surfaces

• posted

Hi everyone!

I need some general advice on drawing 3D houses. What is the best (and fastest) method? What do You use more, surfaces, solids...? How do You create doors and windows? I know the theory on drawing in 3D, but simply don't know where to start with complicated models.

And second, how to create curved surfaces. For example, the body of an acoustic guitar. I don't know how to make top and bottom with surfaces. The only way I could think of is extruding a fited pline, shell it and exploding, so I can assign surfaces (i. e. bodies) to different layers for material assignment. But this is pretty hard for more complicated models, and leaves surfaces where you do not want them. Is there some simpler way by using 3D surfaces after tabsurfing a polyline?

Thank You!

90% solids. the only stuff I use faces for are square to round type surfaces

if you can draw the face of a guitar in 2d , made an extra copy of it., extrude one the thickness of the face (1/8") , offset the other the thickness of the wall (1/8""??), extrude those the thickness of the guitar (5"??) . subtract the inner from the outer & make a copy of the face to become the back, subtract an extruded circle for the whole in ther front. place them all together & union. now add the neck & strings ..ect. now add materials, select your lighting & render away. good luck

You left out the ultimate purpose of the model. How will it be displayed? What kinds of views are you going to use?

I can't, that is the problem. When you look at guitar from above it is curved, and I don't know how to make curved faces (2D faces, not solids, I know how to make it with solids).

Back, front and sides of a guitar are almost always made of different materials, why I wont to draw it with surfaces (3 surfaces, 3 layers,

3 materials - exactly same can be made with solids but it seemed easier with faces), and why I can't use uni>You left out the ultimate purpose of the model. How will it be displayed?
3D views (SE, SW...) and variations on same. Why is that important for faces?

can you draw a front view of the guitar body? make it a polyline & extrude it 1/8" ..

what can't you draw the curved sides? it's simple a section profile extruded.

other wise I have no idea what your question is.

Hi

Now you shuld know how to make the basic Solid as a hollow object, ----- what you need to se, is that if you don't want the same hight all way around, all you need to do, is to make another Solid that shape the first one by subtracting the new. This way ,and by creating a few other Solids , you will end up with a model much more accurate, than one in mesh. You need a curved bottom ------ make another solid with a concave top, subtract exactly those parts of it that you want to form the bottom. P.C.

When you extrude a 2D object it becomes 3D solid. I wanted to know is there some way to draw curved 2D faces (again, 2D not 3D, witch solids always are). But don't worry about it anymore. I give up on idea of curved 2D faces.

Hi You are correct about the guitar, but it is arduous.

3D houses are not in themselves difficult, the key is to have layer control (although you can use planes) to turn off walls and floors etc. The method I use (and which I find quickest and easiest for me) is to have an angled view showing and create objects in the margin/on a sketchpad area. Once I have created the object I need (door, wall, chair etc), I check they layers are right then make it a block.

Objects as block makes assembly a sinch in the angled 3D view - just drag the block into position!
