I do have a VBA routine that may make the process marginally easier. I say “marginal” because it can only deal with Iso geometry aligned to one of the three orthographic planes(XY, XZ, YZ). The routine will convert this geometry back to its orthographic counterpart for subsequent use with the Solid Modeler. There is some additional overhead as the iso geometry must be converted to “Regions” to be compatible with the routine. Regrettably, the routine will only convert isocircles to ellipses with a Radius Ratio of 1. Damn, perhaps I should have used a phrase less impressive than “marginally easier”.
In any event, the attached drawing is an example of the general idea.
