Hi,
When a hatch have been offset in the Model then it appears incorrectly when rendered in a Viewport. It seems that in Viewports the hatch Origin value is not taken into consideration. This means that when adjusting a hatch in the Model to look correct (align along a line for example). This alignment is off in the Viewport.

See screenshots and attached test dxf file in this thread on the forum: https://qcad.org/rsforum/viewtopic.php?f=33&t=6742

Edit: After looking more into this issue is seems it is the Viewport's position that is ignored when transforming the pattern into Viewport space. See the following gif:

Above it can be seen that that pattern is always rendered in 'worldspace' since the pattern is static (the pattern is not moved when the viewport is moved around)
