chrisxib posted a topic in Industrial Forumthe pic is from mastercan 2017 lathe finishing parameters using a nurbs spline as geometry. When using mastercam 2018, the Linear Tolerance field window is missing and the spline is interpolated roughly when machined. I solved this particular problem by simplifying the spline to an arc and reposting. But I need to have a better solution going forward. Any help would be appreciated. Thanks Chris
I'm new to Mastercam 2017 (upgraded from X7), and I'm trying to create a lofted surface with multiple curves using the window option for my chains. The files are cranial scans that get saved as .iges files with curves consisting of lines that from a head (see image). In X7, I'd easily click lofted surface, select the window of all the curves, select a starting point and the surface was created instantly. In Mcam 2017, when I match the surface configuration settings as X7 it takes forever and creates thousands of surfaces that wrap from top to bottom. When I change the setting from NURBS to a curve generated surface, the single surface is created similar to X7. The problem is I need to re-save the file as an .iges and 2017 crashes every time when it's curve generated. When it creates the thousands of surfaces (NURBS setting) I can save as .iges no problem. My goal is to quickly create the SINGLE surface, and re-save just the surface as the new .iges file. Any help would be greatly appreciated!!
