polyline for shell tool

[Anonymous]

Hello,
I want to make a shell at two ends of curves, but only spline can make it (but spline seems unable to draw straight line),
how can I use other line tools (pline, fill etc) to make shell?

PS now I used morph fro one end to the other, then drag point by point (not a direct way)
regards

and an recommendation about workflow-speed in Archicad with huge ammounts of complex shapes: Always make GDL-Library-parts of it - they react much faster in Archicad than the original shapes of the Archicad-tools.
