fuccaro Posted September 22, 2017 Share Posted September 22, 2017 (edited) How can I convert the surface of my solids to triangular faces? In the past I did it by exporting to 3DS (if I remember right) and reimporting it, but AutoCAD 2015 doesn’t support any more that format. I tried to export in STL format (it worked), I opened the .STL file in Inventor (it worked too) and I exported from Inventor in DWG format again. But opening that last DWG in AutoCAD gives nothing . I am not up to date with this modern AutoCAD, the last one I used daily was AutoCAD 2006. Ca someone help me please? Yhank you for the welcome!

ReMark Posted September 22, 2017 Share Posted September 22, 2017 I know of a routine that will convert a solid to either 3Dmeshes or 3Dfaces. Would that be of any use? Here is an image of a solid that I converted using the routine. BTW...welcome back fuccaro. Quote Link to comment Share on other sites More sharing options...
halam Posted September 22, 2017 Share Posted September 22, 2017 Couple of days ago I discovered XEDGES which will create a wireframe of a solid on top. This could be used in combination with edgesurf for creating meshes, not regions which will be result of exploding solids. Quote Link to comment Share on other sites More sharing options...
ReMark Posted September 22, 2017 Share Posted September 22, 2017 Nobody suggested exploding a solid. We're talking a straight conversion from solid to triangular faces or at least that is my interpretation which is what I believe I show in the image previously posted.

halam Posted September 22, 2017 Share Posted September 22, 2017 O Sorry than Quote Link to comment Share on other sites More sharing options...
fuccaro Posted September 25, 2017 Author Share Posted September 25, 2017 Thanks for the answers! XEDGES just extracts the edges from a solid, I need something like "XSURFACES". To get the individual edges doesn't help me since I try to use the surface in a Lisp program. ReMark, that program sounds good, may I have it please?

ReMark Posted September 25, 2017 Share Posted September 25, 2017 This is the program description: Sol2Mesh and Sol2Faces - convert 3DSolids to 3DMeshes or 3DFaces (VLX Lisp for AutoCAD 2011/2012). This is where it can be found: http://www.cadforum.cz/cadforum_en/dl_file.asp?ID=1444 This is a copy of the program which, in order to upload it, I had to add the .zip file extension although it is NOT a zip file. Download and rename the file by removing the .zip file extension and you are good to go. sol2mesh.vlx.zip Quote Link to comment Share on other sites More sharing options...
fuccaro Posted September 25, 2017 Author Share Posted September 25, 2017 Thanks, I downloaded it and I will give it a try tomorrow. Quote Link to comment Share on other sites More sharing options...
bjenk8100 Posted September 25, 2017 Share Posted September 25, 2017 Whats the point/advantage of triangular faces? Quote Link to comment Share on other sites More sharing options...
fuccaro Posted September 26, 2017 Author Share Posted September 26, 2017 The program works just fine, thank you again, ReMark! bjenk8100, writing Lisp programs sometimes I need to find out coordinates on the existing solids. If you try ENTGET on a solid, AutoCAD will return a list that only Einstein's brain can understand. Working with triangles or even with mesh objects is much simpler.

ReMark Posted September 26, 2017 Share Posted September 26, 2017 Glad to hear the program met your needs fuccaro. You're entirely welcomed. Quote Link to comment Share on other sites More sharing options...
