At the moment I’m partnering with a mechanical engineer who uses Spaceclaim as the main design tool. He has worked with another industrial designer who would send him Rhino files. He then just import the Rhino file and start building features on the model in Spaceclaim (which is a very efficient workflow if you have seen it you know that) due to the fact that the two software has a “Round Trip Integration” thing established from many years ago.
THE PROBLEM: The models from me always end up being recognized by his Spaceclaim as “spline faces” while it’s 100% closed polysurface in my Rhino. He claims that the Rhino files he received in the past rarely had this issue. The files he received in the past also contain freeform surfaces, but Spaceclaim can at least recognize the geometric shapes like plane or cylinder. But from my files, even the planes are recognized as “spline face”.
So we’ve been trying different import/export options from both sides, smaller or bigger tolerance. Nothing worked. We called up the other designer he worked with before, that guy didn’t have any special trick. Now we’re stuck at the painful workflow that for every iteration of every part I deliver to him, he will need to spend quite some time, sometimes hours, on stitching the surfaces into an editable solid before he can do his work.
Please share your experience or guess. I tend to believe that my Rhino experience is all right, but please do point it out if by your experience this is related to surfacing technique. Thanks in advance!
FYR, here is the screenshot in his Spaceclaim showing the raw imported surfaces with the message announcing this model is not solid.
