  1. I'm pretty sure that STL files don't contain units. For most applications I think its assumed to be mm and software usually does the conversion during import/export. I use them a lot for 3d printing and I've never had any issues with scale from Vectorworks. Can you set the unit system of your other software temporarily to mm, do the import and then switch back? You could shrink everything before exporting from Vectorworks, but this may not be possible if your model uses architectural PIOs. There was a wishlist item to give more control the STL export function in VW, including scaling, but its never been implemented. Kevin
  2. Thanks. I can identify where the issue is in the geometry and provide two workarounds. I've attached the file. I still can't answer why this area is a problem. The first workaround is to reduce the number of points at the top of the back. It gets you a little bigger radius. The second workaround changes the top of the back to have corners and then fillets off the corners first before applying the other fillets. Kevin Fillet Tool V2020 KM.vwx
  3. 3d Fillet is definitely less robust than it was in earlier versions. I would guess changes were made to allow it to become part of an object's history. @JuanP is there someone from engineering who worked on this change and could speak to changes with the 3d Fillet tool? @MHBrown are you able to post an example extrude and what radius you're trying to achieve on it? I was fighting with it myself earlier in the week and applying smaller fillets to get the fillet to take, editing it's radius afterwards in the OIP. Kevin
  4. Subdivision is probably the answer if you're skilled with it. I tried revolve around rail and it got me close but overall the fillet method above gave the best likeness. Kevin
  5. Lots of good ideas here. If you have a floor that this is sitting on there will always be Z fighting unless one is offset from the other. I think reducing the shell thickness to something like 1mm is likely the solution. Whenever I put something on the floor that has no thickness (eg. a NURBS surface "rug" that has texture but not thickness) I float it about 1mm above the actual floor for this very issue. Kevin
  6. Here's an attempt at the shape. Its not as simple as it appears... which is true of most things that come out of industrial design software. I essentially did it with fillets and solid sections in the end. I tried using lofting but the tools in VW aren't quite up to this shape. The front face isn't completely accurate (you can see the polyline guide I left in) but the footprint and side view are very close. The front face is actually part of an oval in their drawings while the back end is based on arcs. Its the blending of the two that isn't so easy. Kevin RoccboxV1 KM.vwx
  7. You could use the Extrude Along Path method you're proposing if you build the floor separately and add solids. Here's an alternate approach that's much more flexible - Extrude a rectangle that represents the bounding box of your space. Use the 3d Fillet tool to add the fillet curves at the corner and floor. You can do it all at once or they can each have different curves. Using the Shell tool, select the three sides you need to remove and set your thickness as required. Using this method you get nice clean geometry. Kevin Studio Cyc.vwx
  8. It used to be that you could control the export polygon resolution using your current rendering resolution. If you export while your scene is in wireframe it uses the default setting instead. I haven't used the VW>C4D workflow for a while so I'm not sure if that's still true. It might be worth a try. Kevin
  9. Yes, but only if the curves are arc segments and you break them up into individual pieces. Use cylindrical mapping and scale the cylinder to the diameter of your curve. Kevin
  10. I'm not sure you have any control over this. I believe the date format is driven by the system running VW. All the cloud renderings are done on virtual Windows machines. There may be a cloud option to turn off auto-updating of plugin objects but that is not an ideal solution. Kevin
  11. Is this in wireframe or OpenGL? 3d objects usually display as unfilled in wireframe.... Kevin
  12. That's a very good question and something I've asked before. Not sure if there was ever an answer. For years, extruding a line to make a plane was a normal workflow. At some point it changed and was inconsistent (open polylines would become closed shapes instead of just a plane for example). Now I regularly work around it just to be sure. Kevin
  13. In newer versions extruded lines don't behave as well as they should. I always extrude and then convert to NURBS. Alternately I use the Extract tool to extract the surface. Kevin
  14. Unfortunately there doesn't seem to be anyone at NV who is as invested in the community board as JimW was...... Kevin
  15. If your curves are in the correct orientation then you need to use the Fix Profile checkbox in the EAP dialog. You may need to switch the "direction" of one of your curves if the creation fails once you activate the checkbox. Kevin
  16. You can use (Model>3D Powerpack>Unfold Surfaces) but as noted above, it just piles all the pieces on top of each other so you need to sort them out manually. Kevin
  17. Most of the challenge will be file organization, since the Vectorworks users will have access to both layers and classes and you will only have access to Autocad layers (which normally convert to Vectorworks classes). In my experience geometry transfers pretty well. I would stick to solids geometry where possible. Kevin
  18. Another useful workaround is to use the Align/Distribute command along with a 3d locus to accurately align objects to the ground plane or any other boundary. Kevin
  19. Is the object custom built geometry or created using a PIO? I've noticed that some PIO's generate facetted geometry because their code generated 3d polygon geometry not solids geometry, meaning that the facets are baked in by the PIO. Kevin
  20. ^ Don't we all wish the "3D Grabber" interface for the Subdivision tool was available for this step ūüėĀ Kevin
  21. Here's a slightly different take on how to approach this - I started a 2d rectangle as my boundary in Top/Plan and quickly drew a bunch of lines to form a variety of triangles (Far left). Next I used the paint bucket mode of the polygon tool to quickly "draw" the triangles themselves. Then I selected the triangles (polygons) using the Magic Wand tool, used Cut to get them out of the way, deleted the foundation guidelines (rectangle and lines) and paste the triangles back in place. Next I converted the triangles to 3d polygons. Next I converted the 3d triangles to a mesh (second from the right, highlighted in orange). Finally I selected individual join points and moved them in the Z direction. The advantage to this approach is you can use the joined property of the mesh to your advantage. Even if you place 3d depth loci first so you have something to snap to, the mesh is the way to go. Note that I've drawn the panel on its back and it would need to be rotated into its vertical orientation once its complete. Kevin Facetted Surface.vwx
  22. ^ I think a lot of us work this way..... This is a pretty important wish. Kevin
  23. I have this problem all the time. I'm not sure why the sheet layer list in the Publish dialog isn't exactly the same as it appears in the Navigation Palette (stacking order etc.). Its frustrating to have to reorder sheets. Kevin
