Description Regina Henschel 2012-12-17 00:15:56 UTC 
Created attachment 80028 [details]
custom shape with U-command (ANGLEELLIPSE)

The attached document has one modifier. It is used directly by its reference $0 as start angle in the U-command (=ANGLEELLIPSE) in the enhanced-path, and as angle parameter in the handle. But the resulting shape has the handle and the start of the arc at opposite y-positions. The end angle in the enhanced-path is set to 330°. 

In addition the arc is not drawn "clockwise".
Comment 1 Regina Henschel 2012-12-20 16:46:29 UTC 
I have examined the existing predefined custom shapes. It seems, that the problem has not been discovered yet, because all shapes with U command use a fixed angle from 0° to 360° (The cloud-callout has a fixes angle from 0° to 23592960°, which is surely an error.)

Marked is as comfirmed.
Comment 3 Regina Henschel 2013-02-03 13:23:34 UTC 
Tested in PowerPoint 2013: The shape itself is drawn wrong. It is not suitable as reference.
Calligra: The shape is drawn as in AOO, but Calligra has not implemented handles.

I have reworded the command U and T implementation for LibreOffice. https://cgit.freedesktop.org/libreoffice/core/commit/?id=3abe1e83c18c5778d60252092e9cc70c4c63268b
