ArchiCAD 9 Polyline offset bug?

[Anonymous]

I drew a simple polyline in AC 9 and tried to copy an offset (nothing selected-polyline tool active-offset active-magic wand existing polyline-specify offset).
Sometimes (i think depending on the screendistance) nothing seems to have happened. But if I do undo and redo the hotspots of the offset polyline appear (polyline itself not) if I change the view (zoom) the "invisible" polyline appears.
Is this a known bug?

Sorry, forgot to mention it was a single (one segment) straight polyline.

Hielke,
Same problem here. Although it is there. Just do a pan or a zoom and it will show up.
But yes it does seem to be some re-draw bug.

Cheers.

There is another.

If you unify linear elements into a polyline, and if they are not all drawn in the same direction, the offset results, especially walls, can be quite spectacular ... and usually are closed polygon.

Reported.
