zoomer Posted October 2, 2014 Share Posted October 2, 2014 (edited) How to deal with DWG Meshes ? Is there any way to convert them into anything useful ? Like Parasolid Solids ? I mean the don't get the nice red clip caps and are difficult to select as a whole and to edit. Edited October 2, 2014 by zoomer Quote Link to comment
zoomer Posted October 2, 2014 Author Share Posted October 2, 2014 I see that I can do a Solid Addition and then convert that to a Generic Solid Would like to convert Meshes directly to Generic Solids. Edit : Oh, I think I expected to much from Generic Solids, can't f.e. asign a Material to one Face. Beside that they are great for the 3D Modify Tools. OK, I see that I can do everything with a Mesh that I can do with a Generic Solid plus assign materials in Subobject Mode. (Had experienced strange things in 2014 so I didn't think that would be possible) Quote Link to comment
zoomer Posted October 2, 2014 Author Share Posted October 2, 2014 (edited) I recapitulate : Meshes are fine. 1. Wish : It would be nice if Meshes could get the beautiful red Clip Caps when using Clip Cube like other Solids. 2. Wish : Would be fine if I could convert Meshes directly into Generic Solids though. Generic Solids are fine too in most cases too but they don't export well as DXF. They lose solidity and fall into single non welded faces. 3. Wish : It would be very helpful if GS would be exported in welded Faces like Meshes. If needed to be edited on face level, each can be easily converted back to meshes. Edit : 4. Wish It would be very helpful if I could select more than one GS and to Convert them into Meshes - not just into one Mesh. Edited October 2, 2014 by zoomer Quote Link to comment
zoomer Posted October 3, 2014 Author Share Posted October 3, 2014 I see I'm probably in the wrong Forum, should be better in DXF/DWG or Solids Modelling :blush: Meshes from VW export really well in DXF and come nice into Modo. I am really happy with that. But beside Generic Solids and their Faces not welded, the biggest Export Problems I have with all Architectural Objects. Windows and Floors missing Polygons, Stairs have miss aligned Polygons. Quote Link to comment
zoomer Posted October 3, 2014 Author Share Posted October 3, 2014 As you can see, WALLS : are fine now in 2015 STAIRS : have all Faces but many of them miss aligned DOORS have all Faces but many of them miss aligned Quote Link to comment
zoomer Posted October 3, 2014 Author Share Posted October 3, 2014 WINDOWS : Faces are missing. (Front and Back sides) As long as you do not set export to triangulate. (the Missing faces have 4 edges but 5 Vertex Points therefor they come in as 8 2-point Polygons) SLABS : There are most Faces missing. Faces that are there are missaligned. Quote Link to comment
zoomer Posted October 3, 2014 Author Share Posted October 3, 2014 This is what it does in Rendering. If have a normal version with a 1-sided material and a second version with a2-sided material A 2-sided material will help to show miss aligned Faces but it makes it a) much harder to select these Faces and b) leads to problems in OpenGL and errors in GI calculations. A 2-sided material will not help in case of missing faces though. If I reimport the DXF to VW which works fine in 2015 (but needs hours in 2014) Even in VW you will miss the corrupt/missing faces. (WINDOWS and FLOORS) Miss aligned Faces won't attract much attention in VW as it Volume Modelers don't care for Faces Orientation. Even Cinema as a Polygon Modeler does show them but I have seen problems in GI though. But any other Polygon Modeler like Modo or 3DSMax etc. do care about face orientation. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 3, 2014 Vectorworks, Inc Employee Share Posted October 3, 2014 To clarify a few things: Where are these DWGs coming from? You're exporting to DWG with meshes from Vectorworks or you are importing DWGs with meshes in them into Vectorworks? Are you using DXF or DWG format, or both? It seems to alternate in the descriptions. Quote Link to comment
zoomer Posted October 3, 2014 Author Share Posted October 3, 2014 (edited) Sorry Jim, these were to pairs of shoes Part I of this thread is about an very old DWG file I found on my disk. It's Le Corbusier's Villa Savoie I imported as a test. Don't really remeber where it is from, I think this could have been done in Microstation Architekt many years ago. This is about Meshes from DWG which is fine now for me except the wishes I listed. In Part II I re-checked if there are any 2015 imperovements of how Architectural Elements can be brought into Modo for Visualization. (The one whith the images) It's a completely different File. This was done completely in VW 2014 doing some BIM modeling. Walls are fine now in 2015, Each Component Class on its own Layer, Faces aligned. Just there are some problems with Faces in the other Plugins as shown by the images. Edited October 3, 2014 by zoomer Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 3, 2014 Vectorworks, Inc Employee Share Posted October 3, 2014 Gotcha, if you could please send those vwx files to tech@vectorworks.net I can test here and get the requests put in. Quote Link to comment
zoomer Posted October 4, 2014 Author Share Posted October 4, 2014 Done. The VWX is the whole building with 7 floors. What you see on the screen shots is only the second floor (1_OG-LEVEL ZEICHNUNG) You can have my DXF too if you want (zipped 30+ MB) Quote Link to comment
zoomer Posted October 6, 2014 Author Share Posted October 6, 2014 OK, I see that I can do everything with a Mesh that I can do with a Generic Solid plus assign materials in Subobject Mode. (Had experienced strange things in 2014 so I didn't think that would be possible) I can't ! I have to convert to a group first - strange. Quote Link to comment
zoomer Posted October 15, 2014 Author Share Posted October 15, 2014 Any news on the export DXF Competition ? I am wondering that by the new FBX export, (2014 didn't work) there aren't any faces missing in Windows or flipped ! Is it just an export issue with DXF, not a geometry issue ? Just for the stairs only. and I can't really explain myself why the faces are oriented in a random manner for a single part. (The stair body had just different orientation for the side faces vs the rest in DXF) Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 15, 2014 Vectorworks, Inc Employee Share Posted October 15, 2014 None so far, I was not able to determine the source of the problem myself and I haven't heard back yet. Quote Link to comment
zoomer Posted October 15, 2014 Author Share Posted October 15, 2014 Ok, thanks. Quote Link to comment
zoomer Posted November 26, 2014 Author Share Posted November 26, 2014 Seems like it starts with the Extrude or Loft System itself. I think there should be flipped one of the Ground Faces, Start or End Cap. At least for me in DXF there was always one of the horizontal Faces flipped vs the Side Faces and other Ground Face.
