      Ah yeah, that is a restricted area for license holders.

      Anyway, it's drop.rb. πŸ˜‰

          Hello,

          After importing the bmp, I've adjusted height, width, etc. The program then follows through by indexing points and generating a mesh. After that I'm attempting to export as a vrml and the program continues to crash at 49%. I'm sure doing something incorrectly but not sure what. Any suggestions?

          Thanks,
          Jeff

            Hello,

            Are further steps needed prior to exporting as vrml after height, width and depth adjustments have been made along with point indexing and mesh generating? All of these steps have been completed but SU is crashing at the 49% mark while exporting as vrml. Any help will be greatly apprecaited.

            Thanks,
            Jeff

              VRML? What are you using to export that?

                If SketchUp crashes when you export then I'm afraid I can't help, as this plugin has nothing to do with the exporter.

                  Are there further steps needed (other than the ones mentioned) prior to export or should the file theoretically be ready for export?

                    No additional steps. Once it has created the geometry it's done its job.

                    You're problem appear to be with the exporter.

                    You're exporting to a 3d printer? Isn't there a different format then VRML you can use?

                      Yes. I can use other file types such as a 3ds or stl. However, I've tried exporting as a 3ds as well and again, the program crashes at 49% for some reason. Very strange.

                        How big is the geometry you export?
                        Did you use a large bitmap to create the mesh from?

                        Maybe SketchUp.exe is running out of memory.

                        Can you give an example of an image you converted to mesh, which you try to export?

                        Does it happen with all meshes you've generated?

                          In sketchup format (after converting to mesh) the file size is 13megs. I've attached the image for which I'm creating the "bitmap to mesh" from. Its size prior to converting to mesh is 44kb. I think you might be on to something as far as SU running out of memory. Possible work around?

                            First verify it's a memory issue. open Task Manager and monitor the memory usage of SketchUp.exe when you export.

                              That mesh I got from that image you posted was pretty dense. 85K triangles.
                              I ran CleanUp on it afterwards, resulting in 34K triangles.

                              If SU is running out of memory, I'd suggest you try with a smaller bitmap. Also, try to run CleanUp before exporting to get rid of co-planar faces.

                                Thanks very much for the help. The cpu usage is at about 250,000k when the export process hits 49% then climbs to 270k and the program crashes and closes. Is this beyond SU capabilities?

                                  No - it'd be at about 2GB. (Unless you have a 64bit OS and SU8M1 with more than 4GB RAM installed - then it can use up to 4GB.)
                                  It must be something else.

                                    Is the "cleanup" process a function of SU?

                                        Great. I will get this installed as well. Did you have a chance to take a look at the photos of the model I emailed you yesterday? If so, can that be achieved with this program?

                                          Well, it generates the mesh. And I'd think that if you closed that mesh into a solid it should be possible to 3d point the model.

                                          The problem seem to be the exporting. I also see the crashes. I even ran CleanUp on the mesh and it crashed.

                                          Try to scale down the bitmap to half the size and see if it still crashes then.

                                            Scaled down and unfortunately still having the same problem. You mentioned closing the mesh into a solid, is SU capable of completing a task like this? If not, any recommendations as far as a software program that may be capable of creating such a model?
