Strange Crashing Problem


We us 2017Pro a lot for generating STL and DXF/DWG files to output to cnc (via VcarvePro). We are currently trying to generate some mesh that are basically like a hand print in concrete. We take a bitmap image into VcarvePro and do a bitmap trace to generate a vector/line drawing of the perimeter of the print. I use a function in Vcarve to fit curves to the vectors which cleans up most of the un-needed nodes. We then export those vectors from Vcarve in a dxf file and bring it into SU for skinning. I have been trying to use soapskinbubble to skin each closed vector (palm, thumb, index, etc). I have been using settings of 25 on the skinning and then bulb with a pressure of 250. Heres where the problem comes in.

No mater what order, and no matter what sequence I seem to go, farthest I ever get is skinning 2 or three (of the six to eight total) closed loops in the drawing and then SU splats. I have tried welding all the polylines prior to skinning to make them one single line instead of segments, I have tried saving after each skin (it will most always crash on save). And several other attempts at a work around.

The funny thin is, I think it may have something to do with the incoming DXF because for the heck of it I generated dozens of wildly shaped closed loops within SU, all in the same drawing, and skinned them all and SU and Soapskin worked flawlessly.

When I get the splat I get re-directed to the forum thread about Intel graphics card issues (4400). Im pretty sure thats not the issue but I went through the paces of updating my drivers, un-installing and re-installing SU (royal pain in the butt). And no change.

Im only able to export the line drawing from Vcarve in dxf, svg, eps, and AI. I wish there was a plugin for SU to generate an automatic outline from an image. That would be handy.

Sorry for the length but thought maybe someone would have some input.

add a sample bitmap file and maybe @jimhami42 can test it on his bitmap import plugin…



If you can generate “clean” artwork as color BMP files, this plugin might work for you:


Thanks for the input guys. No offense but was looking to a solution to the problem with our current capacity. It seemed there was clearly a problem with the DXF import and then upon reading a different post from the wizard Dave Richards we found the solution. We are now able to generate skins with no problem what so ever. Thank goodness.

Thanks again,
