Cesar R Posted July 25, 2003 Share Posted July 25, 2003 I have imported my model from archicad via 3ds in to ACAD. However the model is poly (faces) I think , ut not solids. Is there a way to convert them into solids via a command or tranlator?. The person I am working with will like to have the model in ACAD solids, but to me it is much easier to model in archicad, not mention making revisions is a breeze those "coookie cutter" apps.

psyanide Posted July 25, 2003 Share Posted July 25, 2003 I really don't think so. The best you are likely to get will be a lisp that will join all the faces together into a mesh. (AutoCAD solids are not particularly good anyway and the filesize is just plain ridiculous) Link to comment Share on other sites More sharing options...
Hazdaz Posted July 25, 2003 Share Posted July 25, 2003 Ain't gonna happen. Ya better start extruding and basically starting from scratchif you want solids. Link to comment Share on other sites More sharing options...
Kerry Thompson Posted July 25, 2003 Share Posted July 25, 2003 Hi Cesar I don't think there is any way of converting the mesh to solids. I would attach the mesh model to an AutoCAD file as an xref and use it as a guide to rebuild the model in ACIS or (ADT mass elements if you have ADT) Kerry Thompson Link to comment Share on other sites More sharing options...
Cesar R Posted July 25, 2003 Author Share Posted July 25, 2003 wow... ok , what a shame its not possible.... well, I am not redoingt this model luckily, but in the future I will just model I ACAD if I want solids. What other programs can you model in and have them open in ACAD as solids? anything, or are solids and autocad thing? (I dont mean to sound ignorant, but someone told me that Rhino produces solids?)

Wojciech Klepacki Posted July 26, 2003 Share Posted July 26, 2003 I dont mean to sound ignorant, but someone told me that Rhino produces solids? Actually the answer is: YES, Rhinoceros 3D makes solids, but u can't import them directly to Acad. U may use dwg export type with faces or use ACIS file format. rgds, Wojciech Klepacki Link to comment Share on other sites More sharing options...
Kerry Thompson Posted July 26, 2003 Share Posted July 26, 2003 Hi Wojciech So – can we take a mesh file, generated in ArchiCAD, exported to AutoCAD, imported into Rhino, and then exported to dwg in ACIS format? Kerry Link to comment Share on other sites More sharing options...
Cesar R Posted July 26, 2003 Author Share Posted July 26, 2003 What is ACIS format?? btw, I am looking to buy rhino any comments on the modeler and work flow? Link to comment Share on other sites More sharing options...
Cesar R Posted July 27, 2003 Author Share Posted July 27, 2003 Ok, I am still not sure what the ACIS format is, however I know this.. Kerry... I created a solid in rhino (demo version btw) and exported as ACIS ACAD. Inported it into ADT and was a solid and was able to subtract an auto cad solid from it. I am pretty sure that if import an archicad model and do the same it will work. I will try it and let you guys now... ... ok, I imported a 3DS file and tried to save it as ACis and i got the following error "Meshes can not be exported to ACIS SAT files".. ok we're almost there help anyone?

Kerry Thompson Posted July 27, 2003 Share Posted July 27, 2003 Hi Cesar ACIS is the solids modelling kernel used in AutoCAD though I understand that they are in the process of developing their own called shape manager ???. I can see that a Rhino solid can export to an AutoCAD solid but I am sceptical about a surface mesh being able to be converted to a solid. Somebody prove me wrong.

Wojciech Klepacki Posted July 27, 2003 Share Posted July 27, 2003 Hi Kerry, So – can we take a mesh file, generated in ArchiCAD, exported to AutoCAD, imported into Rhino, and then exported to dwg in ACIS format? Sure u can do it, but I wonder why? Becouse acis format will not give u solids by itself. rgds, Wojciech Klepacki Link to comment Share on other sites More sharing options...
Cesar R Posted July 27, 2003 Author Share Posted July 27, 2003 Sure u can do it, but I wonder why? Becouse acis format will not give u solids by itself. Then what else would it give you? I got a solid on my test Link to comment Share on other sites More sharing options...
Wojciech Klepacki Posted July 27, 2003 Share Posted July 27, 2003 Hi Cesar, I mean, that ACIS will not automatically convert faces to solids. In Rhino u can do it manually (glue or stick it) or try to use this: http://www.npowersoftware.com/ I don't know this software (I don't use it personally - 550USD for Viz/Max), but I've heared a good recommendation. rgds, Wojciech Klepacki Link to comment Share on other sites More sharing options...
G Posted November 24, 2003 Share Posted November 24, 2003 you could try the m2s.lsp on the following link. it claims to convert any mesh to solid. goodluck G http://www.accustudio.com/marketplace/freeware.htm Link to comment Share on other sites More sharing options...
Cesar R Posted November 25, 2003 Author Share Posted November 25, 2003 hi, thanks, i will look into it and give it a try Link to comment Share on other sites More sharing options...
kid Posted November 25, 2003 Share Posted November 25, 2003 If you do choose to go the Rhino route...if you're importing polygonal data into Rhino, exporting to ACIS .sat format will not give you ACIS solids. Only closed poly-surfaces will export as ACIS solids. However, you can use the Smurf plugin for Rhino which converts polygons to nurbs that can then be joined to create closed poly-surfaces.

Antisthenes Posted October 4, 2006 Share Posted October 4, 2006 use RHinoceros command MeshtoSolid. it will create a nurbs face for each mesh face but it will be closed polysurffaces and there for a nurbs solid. ya or use smurf or other 3d party mesh to nurbs simplfiers or just remake curves on your mesh to use to create new solids from.
