Line drawing and T-Splines

[Antoine]

When running the Create Line Drawing command on a hull made with T-spline, the isocurves show on the drawing. The only way to get rid of them is to convert the surface back to Rhino Nurbs.
Is this a normal behaving ?

Hello,

We have confirmed the behavior and are working on a fix for the next release.  It is caused by the way TSplines are stored; it sees the isocurves as edge curves.

As you noted, you can either convert the surface back to a regular nurb surface for creating the lines drawing, or you can delete the isocurves from the drawing once it is made.
