sdds Posted September 6, 2007 Share Posted September 6, 2007 quick couple of q's chaps, 1) how would you go about modeling stepped flashing in autocad, extrude or using the 3d face tool? 2) When modeling complex roof lines I currently use basic lines and fill with faces then export to max or c4d (thanks to strats tips)... but can these faces be converted into a solid in AC to take advantage of the solid editing tools? thanks guys.. simon Link to comment Share on other sites More sharing options...
JamesTaylor Posted September 6, 2007 Share Posted September 6, 2007 1. i'd draw the outline and then extrude to give it the required thickness. - getting the outline steps to match the steps / line of mortar between a brick material applied in another app is a different task all to gether tho! 2. if you are using a newer version of CAD (2007 / 08) i'm pretty sure you can use the PressPull Tool to extrude a 2d face / poly mesh into 3D. I think what actually happens is that the edge loop if the face is extracted and then extruded, leaving the original 2d face as it is. Link to comment Share on other sites More sharing options...
gfa2 Posted September 6, 2007 Share Posted September 6, 2007 Yeah, I'd definetly use extruded solids and not faces....for just about everything. Link to comment Share on other sites More sharing options...
sdds Posted September 6, 2007 Author Share Posted September 6, 2007 thanks, will have a go at that.. Gary you say using just solids for most things but wouldn't a complex roof be a slicing nightmare with solids alone? I am not very experienced though lol.. Thanks for the help Link to comment Share on other sites More sharing options...
gfa2 Posted September 6, 2007 Share Posted September 6, 2007 Boolean operations aren't really recommended in max, but in Autocad you can subtract and union all day long and be just fine. I've done some pretty intense roofs with solids. In addition to subtract and union and all that, you can hold the Control key down while you pick the grips of the solid and actually move them around and modify them. Kind of like vertex or edge modifications in max. That can be helpful. Link to comment Share on other sites More sharing options...
STRAT Posted September 6, 2007 Share Posted September 6, 2007 in acad i'd personally face 99% of my work. not solids. Link to comment Share on other sites More sharing options...

sdds Posted September 6, 2007 Author Share Posted September 6, 2007 Thanks guys had a play... PS. Strat sorry about the pm ramble, felt a bit down at the time.. Link to comment Share on other sites More sharing options...
STRAT Posted September 6, 2007 Share Posted September 6, 2007 hey, any time mate. havent had time to reply yet as i've been out on green-screen location duties the last day or so and havent had much pc time. but i will Link to comment Share on other sites More sharing options...
Hazdaz Posted September 9, 2007 Share Posted September 9, 2007 NEVER EVER use anything besides Solids in a CAD program.* When are architectural-types going to learn that basic law of the CAD world? Us mechanical/engineering-types have known this rule for ages now. Geez guys, welcome to the new millennium. Next you guys are going to be touting parametric modeling as the "new" fangled way to model. *ok, well maybe ONLY if you need to do highly organic shapes, but that doesn't exactly come up all that often in architectural CAD.

sdds Posted September 10, 2007 Author Share Posted September 10, 2007 that seemed a bit unnecessarily bitter.. Thanks for clarifying it paul. When you export a faced model out of acad its vertexes are welded anyway. Think I will use both solid and face modeling. Link to comment Share on other sites More sharing options...
