Hi,
in v8 latest src
try to offsetsrf (solid sharp corners) these polysurfaces by 2cm outwards and see why it fails. it seems like a simple shape to fail.

I believe this is a tolerance issue. The offset polysurface is closed after changing the absolute tolerance from 0.0001 to 0.00001 units. File units is meters…
0.0001 units would be 0.1 mm
And you are 1371 km away from W0,0,0

Those surfaces don’t even render in shaded mode for me.
yeah my rocket landed right there 
. most of the time i dont have problems far from origin but sometimes i do. especially in this “simple” case i would say the offsetsrf could work even far from origin. sometimes i have to move it to 0 then do the work and move right back.
Display mode is set to Object…

they are set to wireframe mode, just set display mode by view

Hi @ftzuk
They have SetObjectDisplayMode activated - Run it with the UseView switch to return them to “normal”.

when moved to world 0 it seems to work well. it was said above that tighteing tolerance also helped. how is far from origin intertwined in this case? maybe simple solution is for the command to tighten tolerance when it fails or give you a prompt asking about it ?
devil lies in details. try distance 0,02 which is 2cm

Yeah sorry 
0.02 offset does indeed create open polysurface.
