  1. Sorry for the delayed response on this. Point clouds can be challenging to work with, and on that project, the generated mesh was very dense and difficult to read. The mesh provided a very general idea of geometry but wasn't especially useful beyond that. The specifics of the site and the scan likely contributed to the challenges. The project was a massive industrial facility with many pipes, tanks, and decaying/irregular shapes/forms. The point cloud scan did not include color information. The scan included multiple buildings, with complex section properties. I recently had experience working with Matterport OBJ files, and have had much more success. The integration of Matterpak files in VW is fantastic. The obj files import quickly into VW. The color scans help tremendously since the OBJ files include renderworks textures. The files import to scale. Matterport2 cameras, however, have different limitations. They don't scan high spaces well, and they work best in interior settings.
  2. I figured out how to fix. When you set up the column, you deselect "Use Capital" and "Use Base" in the architectural settings.
  3. I created a new structural column in VW2022. When I copy and paste the column, I get an error message saying that the Capital Height must be greater than 0" What can I do to fix?
  4. I downloaded and learned it after somebody on the VW site recommended it. I was able to successfully convert a complex point cloud scan into a mesh. The software takes a long time to process. I followed these instructions. https://blogs.gre.ac.uk/designsupport/3d-realisation/laser-scanning/meshlab-point-cloud-to-mesh/
  5. In many ways, Vectorworks tries to look and feel like Sketchup, but then it's so weirdly illogical at times. I've always wondered what technical issues prevent CGS Solids/Extrudes from receiving color and transparency like the image shown below. To generate this image in a shaded model space, I have to assign a texture with the correct color and opacity, and then duplicate the object and turn off the fills to show edges. Curious as to why.
  6. Thanks! For now, my workflow will be to trace the point cloud in an annotation viewport and copy the linework back to a 2d drawing layer. VW 2022 does appear to have made some progress with "drawing" in 3D. In the latest version, one can indeed draw on a working plane and project the information back to the active layer plane (which accomplishes flattening the vector information), but the point cloud sections don't render. VW2022 also crashes whenever one combines shaded render backgrounds and hidden line foregrounds. I reckon somebody also knows about this bug. I hope SP3 fixes some of these issues. *
  7. I would love to bring the whole project into VW 2022. But I think point clouds don't render in shaded section viewports. In 2022 are 2d objects layer plane?
  8. I am having issues getting dwg backgrounds out of Vectorworks after drawing over sections of a point cloud. I am working in VW2020 due to issues with rendering in future versions. As you can see from the attached screenshots, I've been able to section the point cloud, create working planes, and draw over the section in the active working plane to trace the outlines of the objects. In the model, some objects are 2d, and others are 3d. When I export the viewports from the sheet layers, only the 3d objects show up. What should I do to get 2d vector-based output so I can share this work with others and continue developing the drawing details? Maybe this is fundamentally a question about the relationship between 2d and 3d objects in Vectorworks. I would be fine, flattening the vector stuff so I can draw. But it would be better to continue to work in 3d so I can develop a model of the facility. Any thoughts as to best practices?
  9. Point clouds seem not to render correctly in VW2022, viewports. I had to backsave all my models on my project to VW2020, for me to work with them. Not sure what is going on. I assumed it was something to do with the switch to the new Shaded Renderer that replaced Open GL.
  10. That makes sense. But not seeing them at a glance, makes them harder to find.... Any downsides to turning Unified View off from a performance perspective?
  11. Just curious... Without disabling unified view, where do you do draw 2D details in the 3D workspace, especially if they are at different scales? We make layers just for 2d Details, various scales. This enables things to more easily move from file to file... One option is to make everything a symbol. But making everything symbols is a little confusing for the average user.
  12. Interesting.... If the walls are on the same class, one can either duplicate or "copy and paste in place" and they will purge. If you switch classes or layers the walls won't purge.
  13. @zoomer You probably know this.... On a test file, the command does seem to delete walls if they are duplicated in place. Probably when some slight modification is made to the wall, they are no longer exactly the same, and that is when the command fails to purge.
  14. In the purge command you can delete the Coincident Duplicate Objects. Not sure how smart this will be and I would save your drawing beforehand....
