crushdrive Posted May 14, 2007 Share Posted May 14, 2007 Hi..CG Guru, I need help on how to model in cad with out solids to lessen the file size of my model. i usually model veritcal structures with curved modules e.i irregular shapes but i wanted not to use solids on them because of the file sze issue. 1. Is there any commands in cad that i could model aside using extrudes or solids. 2. I hve tried using Poly mesh but some of them dont show when i import them in 3Dmax. 3. Is the any Plugin or apps to model (In detailed) without no solids at all. 4. Polyface mesh in CAD how do they do that? what commands to use for is curves & irregular composite shapes. I appreciate any help to learn more on modelling, anyway in using Rhino+Cad for Modelling+3DMax for rendering. Tutorials links is much appreciated. Thanks in advance.

louis.cho Posted May 14, 2007 Share Posted May 14, 2007 Why not model in Max, what kind of model it is to be so huge? I don't think using 3d faces will be better. I think polymodeling is the best way Link to comment Share on other sites More sharing options...

I think polymodeling is the best way completely agree. if file size is the issue, model in max. besides, you won't have problems with unwanted lines in booleans. edit poly is The Way eduardo Link to comment Share on other sites More sharing options...

ipxstudios Posted May 14, 2007 Share Posted May 14, 2007 When you model in Max the file size is going to be much smaller Link to comment Share on other sites More sharing options...
mskin Posted May 14, 2007 Share Posted May 14, 2007 I was very reluctant to begin modeling in max after bociming so comfortable with it in acad, but i am sooooooo glad i did. I have more control over geomtry and poly counts etc and i model much much quicker. i still do a lot of line work in acad. Take some time to become more comfortable with modeiling in max - I think you will be pleased. Link to comment Share on other sites More sharing options...
neil poppleton Posted May 14, 2007 Share Posted May 14, 2007 solid modeling in cad and file linking is the perfect system in my humble opinion, the accuracy and more important easy change and update when everything changes as it always does, is a great workflow.

Guest nazcaLine Posted May 14, 2007 Share Posted May 14, 2007 in your opinion of course yup. i started modeling in cad, but changed my mind when i discovered that if a room had to grow , say, 50 cm, all i had to do in max is just move vertices. in cad, i would have had to slice, move, extrude faces, and weld the two parts. unless i missed something...maybe there's another way to do that and i never knew...i'm talking about cad 2002, 2004 and 2006 of course.

Hazdaz Posted May 14, 2007 Share Posted May 14, 2007 I have to say that if you aren't using Solids in CAD, then you really aren't modeling in CAD at all. I also have to question the reasoning behind this - I use Solids exclusively in AutoCAD and work on some complex assemblies and in general file size is not a huge issue... yea, files can get big, but it's not like they would be that much smaller if exploded down to faces, and they would be dramatically less useful. After all, mathematically defining a cube with 8 points has got to be more efficient than defining 6 faces, each with 4 points of their own.

3DEXTRUDE Posted May 15, 2007 Share Posted May 15, 2007 completely agree. if file size is the issue, model in max. besides, you won't have problems with unwanted lines in booleans. edit poly is The Way eduardo That also depends on your knowledge of CAD. Since i know jack about cad programs, i use 3ds max for all my modeling in my office and it works out just fine. cheerz.. Link to comment Share on other sites More sharing options...
allwhiz Posted May 15, 2007 Share Posted May 15, 2007 what cad? GOOD DAY! I'm still practicing 3d max, Can you help me how to import .mtl or .mat extension ,material library? Coz i have material library from previous max versions and it cant be loaded when i open my files THANKS! Link to comment Share on other sites More sharing options...

alfienoakes Posted May 15, 2007 Share Posted May 15, 2007 Modeling in CAD with no solids, is about as hard as you can get.. By no solids, I am also assuming there are no mass elements, AEC etc.. I use ADT 2007, and do 90% of my modeling using the ADT objects. Mix that with the mass elements, and then into VIZ for any trickier shapes.. The file sizes can get large, but once you bang the ADT file into max / viz it handles it really well.. so no real problems.. Max / viz native file format is smaller and more compact than ADT /ACAD.. but it depends how big your model is, and how old your machine is as well.. Dont dismiss all the good tools at your disposal just because the files my be getting a bit too large.... it would be easier and cheaper in the long run to buy a new machine..!!!

crushdrive Posted May 15, 2007 Author Share Posted May 15, 2007 I have to say that if you aren't using Solids in CAD, then you really aren't modeling in CAD at all. Yeah i agree with you Hazdaz its aren't modeling in cad at all..i've read one thread before that he model with autoCad 99% with no solids & im just wondering how he model. i guess everyone is right, its better to model in 3DMax and get acquinted with it. Thank you all. Satisfied & agreed! "crush" Link to comment Share on other sites More sharing options...
STRAT Posted May 15, 2007 Share Posted May 15, 2007 i guess everyone is right, its better to model in 3DMax and get acquinted with it. no no no no no!!!!! dont get hoodwinked i model full 3d in max, cinema and autocad. each is utillised differently. thinking like that is most arrogant and naive. and what of those who dont have max? are they on a hiding to nothing? and if you cant figure out how an artist who doesnt use solids can model in autocad atall then you aren't in any position to give out advise. i choose not to model in solids yet you class me as someone who cant really model 'properly' ? sorry to sound off here, only this single minded advise just isn't good enough. peeps who are in the know can make up their own minds. Nubes follow these boards for career making advise. Link to comment Share on other sites More sharing options...
crushdrive Posted May 15, 2007 Author Share Posted May 15, 2007 no no no no no!!!!! dont get hoodwinked "you aren't in any position to give out advise. i choose not to model in solids yet you class me as someone who cant really model 'properly' ?" i did not at all say that i class you that can't model properly, & im not giving advise at all. Im just saying that i myself has to get use to 3Dmax in modeling too & not concentrating in Autocad & Rhino. As you have said that artist should not use only one medium but use what he thinks is better. Link to comment Share on other sites More sharing options...
