Jane,<br><br> The following:<br><br> create vertex 0 0 0 <br> create vertex 1 0 1<br> create vertex 2 0 0 <br> create curve vertex 1 2 3 spline<br><br>should create a curve that includes all three vertices. It does so in Cubit with the Acis engine but with OCC, the middle vertex (3) gets left out. I looked a bit into the code with debug but I didn't come close to having an idea what the problem may be.<br>
<br>Thanks,<br><br> - Boyd<br>
