So there is a solution for the disturbed curves. Glad to here!shoogen wrote: ulrich1a wrote:Your picture from the last post is a Draft-Projection or a Drawing-Projection?
Drawing
I compared a Drawing projection from
OS: Debian GNU/Linux 8.0 (jessie)

with

Python version: 2.6.2
Qt version: 4.5.2
Coin version: 3.1.0
SoQt version: 1.4.1
OCC version: 6.5.1
The projection with OCC 6.5.1 has not the much visible hidden lines, where as the projection with OCC6.7.1 looks like yours except that it has also the disturbed lines.
Was there a change in the api for the projection function between those OCC releases?
