new to 3d

I'm starting to do a 3d model of the house I've drawn. Is it best to extrude walls or just give the wall line thickness as a start. I just give them thickness and thats what I do with the window mullions, doors etc. too.

How you create a 3d model affects the rendering in the final stage, doesn't it?

Hope i'm making sense. Just new at this and I want to do something more. Been stuck in 2d for soooo long. Thanks.

Better make the walls solid. it has more advntages over just putting thickness to the line. hollow walls will have problems later when youll be placing doors and windows.

Here's a sample of a model I did back then. most entities are solid. started with extruding the exterior walls of the plan, then used subtract for the fenestrations.

attaching materials will also be a lot easier when your entities are solid.

You should use to make wall for "polysolid" command.This will be easy to make your hit.

I use the press pull command in acad. Its so easy. I think that it is only in versions 2007 +

Thanks guys....at least I know how to start modelling correctly. I understand polysolid, 3dpoly, extrude, regions, union and subtract. I managed to do the walls and window mullions using all those commands.

So when you do those details on the windows, railings and roof , is that when you play around with the UCS. Having problems understanding UCS too. Any simple explanation please....

When working on a window for example it helps to reposition the UCS to somewhere on the window itself. You should work off the UCS toolbar. It will allow you to, among other things, rotate around the X, Y and Z axis and reposition the Origin.

No simple explanation for that, but just a hint. In 3D, manipulation of the UCS is the key to moving around 3D. you will from time to time be rotating the UCS in order to reposition your crosshair to the proper orientation. im not in front of my CAD pc, but will give a quick tip after the weekend. try to browse also the tutorials at the home page.
