When importing a runner (or channel) as an iges curve/spline it is divided in many segments
hence many beam elements - which basically does not follow meshing rules.
The workaround is to manually create overlaid lines on spline/curve in CAD - time consuming.
I would like to see an import option added, where you can set a division and/or chord height for spline.

The imported iges file as:
1) curve/spline
2) lines
