3D Roof

Can someone give me a few ideas on how to create a sophisticated 3d roof in AutoCAD. I have different pitches, levels and dome roof.

ADT or plain vanilla?
Personally, I've avoided using AutoCAD for complex roof designs because it doesn't do them very well. You'd be better off getting Sketchup and importing into AutoCAD.

The post clearly asked about AutoCad. Not what software should I convert to, you silly goose.

I answered the question, and I'll do it again: AUTOCAD SUCKS FOR SOPHISTICATED ROOFS. I DON'T USE IT FOR THAT REASON.
I've got many years of 3D modeling experience. I got my start in 3D in AutoCAD. I abandoned it quickly for BETTER software.
So, maybe it can do sophisticated roofs, I don't know because it's crummy software for doing sophisticated roofs. I made a suggestion on how to make the roof using DIFFERENT software because it will be easier to do. You came looking for free advice, then insulted me when I told you what I thought.
So, I'll repeat it again (I think this is the 3rd tim): Autocad doesn't do sophisticated roofs without extreme pain.

Now this answer tell you how to do this in AutoCAD -- see I even spelled it right -- ,but it do not follow convensions , how things are expected to be done, still if what you want is a reliable 3D drawing of something that acturly can be build and want a complicated roof construction to put up with no foults or impossible places , then there are one method that allow just anythingm still if you are a rigid minded builder who say "what we allready can do, is good enough " then I am sorry as this ask you to open your mind and realise the vision . Anyway take a look how this system involve the intire building foundation structure, and remember that also with tradisional rigid wood beam structure the rain will enter untill you cover the basic structure ;

Now if you are interested I can post roofs in any form to show hoe any roof form can be generated with this system , just remember that it is just one material you need, sheet materials and please be prepared the responses bound to come , that this is strange and new and not "as we use to make it". Still this method challance anything.

I'm going to try to answer, but the first thing to do is to decide what kind entities are required to do the job. Domes are easy, of course: use a SPHERE or REVSURF.
Rectangular flat sloping planes can easily be done with a LINE with THICKNESS, once you've set up the UCS properly. A 3DFACE works without the set up of the LINE approach but you have to know the coordinates of the corners.
Warped planes and other types of shapes are trickier.
Your question is very general, but if you are just starting out, manipulating POINT FILTERS, UCSs, VIEWs and even VPORTs is crucial to success. I suggest you study the help on these topics, and repost in an AutoCAD group.
(I have some little custom LISP routines that make some of these things easier on my CAD webpages. One of them is specifically for pitched drawing roofs, and holes in them.)

If you need to model the interior as well as the exterior, then solids are not for you.

3DFACES are pretty simple things, so the basics is all there is. The help file will tell you everything you need to know about using UCS, if you are patient.

AutoCAD is still a royal pain to use for building roofs... Sketchup really might be the trick. The real program for building complex interior roofs is HOK's defunct drawVision. That was the BEST program for building complex models (but you had to build them polygon by polygon...still a great piece of software).
You could also try http://www.gehrytechnologies.com/products-designer.html - I've never seen it in person, or used it, and it seems terribly expensive

So that's what he does with those fees.

I've seen that in the warez groups in days gone by and it is a HUGE download. No, I didn't grab it. I'm quite capable of wadding foil and throwing it in the corner without software assistance, thank you.

True --- then you just need a craftsman with two hands and a jigsaw, someone who can read the numbers on the paper drawing -- that is case the parts have been processed to be flat on the ucs or in other way's prepared to be made. See this is what I find so fun about it, architects can draw utopia and deliver that drawing as if this deliver innovation and newthinking, the CAD drawings still is finished when there are a few solids to show the form still, --- wasn't this about engaging the intire process, deliver some new tools , not just display something as how it will look finished on a screen , nomatter how refined the rendering calculations are that do not deliver even the old-fasion works drawings ; do it make sense when the craftsman then have to look at the drawing and fiddle from the math. perfect 3D drawing ? Realy I hardly call it progress.

I'll mention that AutoCAD has its own news server with all sorts of groups with *specialists* on them that are quite capable of answering just about any question. Just watch out for that one dood that chastizes everyone for having not upgraded to the most recent release. LOL I don't have that server loaded on this machine so I can't say what it is called, perhaps someone else here knows what it is.
