Mr.Heliotropic Posted April 23, 2009 Share Posted April 23, 2009 Hey 3D modellers I have a problem extruding 2D lines I have created in Illustrator (DWG) into 3D shapes. It usually only extrudes the line itself creating a ribbon effect. Selecting Cap End, etc appears to do no help. Any advice? Would be much appreciated.. Also Hello i'm from Perth Australia, use a bit of 3D to create images, usually fairly non-realistic. First post. Link to comment Share on other sites More sharing options...
rmccoy Posted April 23, 2009 Share Posted April 23, 2009 you most likely have a broken vertex or two. In the edit tab of your line/editable spline select the vertex sub object level. draw a selection window over your different vertexes and try and weld them. that should solve your problem. also under the utilities tab there is a button called shape check. You can click the shape check button and then select your spline. it should show you a red box around the vertex that is broken. Link to comment Share on other sites More sharing options...
sagartotal3ds Posted April 23, 2009 Share Posted April 23, 2009 May be you should try to attach your model with a max box so that it will take the property of max and his property will be collapse or you can try what senior member is saying Thanks Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 23, 2009 Author Share Posted April 23, 2009 Thanks for that I will look closer at the 2d shapes for any gaps and try the welding option, and report back... Thanks! Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 23, 2009 Author Share Posted April 23, 2009 Ok I have just tried the welding method unsuccesfully. Using the Shape Check utility informs me of where the shape intersects itself? These don't appear to be gaps but still when i fuse around so the shape no longer intersects itself this still creates the ribbon effect when i extrude. Could it be something to do with when i import the DWG file, should a use a different file format instead of DWG? Would posting any pics of the problem help? Thanks Link to comment Share on other sites More sharing options...
DavidR Posted April 23, 2009 Share Posted April 23, 2009 It would help even more if you posted your scene, stripped except for the spline. Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 23, 2009 Author Share Posted April 23, 2009 is there a way i can post it without ten posts...it keeps stopping me posting a web address Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 23, 2009 Author Share Posted April 23, 2009 ive put it on a website kind like www dot members dot iinet dot net dot au /~macleodperth/scenextrude.max Link to comment Share on other sites More sharing options...
Greg Law Posted April 23, 2009 Share Posted April 23, 2009 Have you tried adding a Edit poly modifier to it first before extruding? Link to comment Share on other sites More sharing options...
rmccoy Posted April 24, 2009 Share Posted April 24, 2009 Have you tried adding a Edit poly modifier to it first before extruding? You can not do this. The extrude modifier must be placed before the editable poly modifier. If you select the vertex (in editable spline sub-object level) that has the red box, you can move around the individual bezier handles. Just make them not cross over each other.

Greg Law Posted April 24, 2009 Share Posted April 24, 2009 If you use the edit poly modifier you can use it's extrude function. I don't see the problem with that. It is still in the stack. Link to comment Share on other sites More sharing options...

Point Taken There are some many different ways to do things in max. I checked the file that was posted. I had to delete a few segments and weld the vertexes where the red box showed up using the shape check utility. I uploaded the file I worked on. I'm using Max Design 2009 so if you can't open the file just use the above method to fix the problem. Works like a charm. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted April 24, 2009 Share Posted April 24, 2009 Could it be something to do with when i import the DWG file, should a use a different file format instead of DWG? Did you try bringing it in as an Illustrator file, instead of DWG? Just save back to Illustrator 8, and it will import without a problem. Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 24, 2009 Author Share Posted April 24, 2009 Really appreciate all the help, but i still cannot seem to find a solution When i try and import an illustrator file i get a message "Line in file exceeds 255 characters" followed by... "Improper file format" The extude option within the edit poly modifier seems to have no effect on the shape at all, it's as if it's determined not to extrude! When I use the shape check utility i get two "Shape Self-Intersects" red boxes, i fuse the surrounding vertices (using a much greater area than needed to be sure any problem is removed). Then i reuse the shape check utility and it highlights the exact same locations even though they appear as a completely straight line now. Applying the extrude function after this fusing still continues to produce ribbon. Any ideas? Link to comment Share on other sites More sharing options...
rmccoy Posted April 24, 2009 Share Posted April 24, 2009 can you upload both your current max file and your illustrator file? Link to comment Share on other sites More sharing options...

Mr.Heliotropic Posted April 24, 2009 Author Share Posted April 24, 2009 the scene file is at www dot members dot iinet dot net dot au /~macleodperth/scenextrude.max the illustrator file is at www dot members dot iinet dot net dot au /~macleodperth/backai.ai "...and this was saving back to Illustrator 8 version?" Im using Illustrator version 9, and i dont see any option that specifically states version 8 when saving or exporting....i have just been saving as Illustrator Ai option which again doesnt state a version...but im using illustrator version 9....?

nelpiper Posted April 24, 2009 Share Posted April 24, 2009 I know it sounds strange but sometimes you have two vertices exactly at the same spot and MAX has a hard time seeing that. So, if you're welding the vertices and it's not working, try first fusing the vertices and then weld them together. Hopefully this will solve your "ribbon" effect. Good luck.

Save as you would normally in Illustrator. When the dialog box pops up, drop the version down from 9 to Illustrator 8. Link to comment Share on other sites More sharing options...
Mr.Heliotropic Posted April 24, 2009 Author Share Posted April 24, 2009 ah i get ya....was really hoping that would solve it but no...still the ribbon Link to comment Share on other sites More sharing options...
Scott Dombrowski Posted April 24, 2009 Share Posted April 24, 2009 Your problem is in some vertices on the left side. Clean those up and you'll have a closed spline (confirmed when you select the spline in spline subobject mode). Closed spline = working extrude.

Mr.Heliotropic Posted April 25, 2009 Author Share Posted April 25, 2009 cool, thanks for the pics, and the advice (from everyone!) I will keep trying, Seeing in that second picture where it tells you if the spline is closed could be useful. I remember after fusing some vertices that shape check still suggested they were there, but perhaps i need to weld instead of fuse? Is there a good (quick) method for reduce number of vertices and self intersects? thanks for all the help! Link to comment Share on other sites More sharing options...
rmccoy Posted April 25, 2009 Share Posted April 25, 2009 I remember after fusing some vertices that shape check still suggested they were there, but perhaps i need to weld instead of fuse? Fuse and then weld. fusing will bring the vertexes together and then welding them will make them into one object. Link to comment Share on other sites More sharing options...
