Linetype diplay with joined curves

Serengeti (Rhino WIP)

When I join some segments of curves that have been pulled onto a surface, the linetype starts over at each"join":

If I remove a control point, sometimes two, the linetype is displayed correctly:

There’s a setting that controls that, if I’m not mistaken. On my phone now, so I can’t check.

LinetypeDisplay, then the command line PatternBySegment Yes/No option. Unfortunately it’s a global setting, not per object

Thanks Matt, I’ll try this

I can’t find a way to get this to work…
Here’s my test file. In the perspective viewport we see a polysurface with two curves pulled onto. These curves would have an alternating pattern as the lines showing in the Top viewport.
Any help would be very appreciated!
