how do I create offset hatches?

An utter deja-vue experience...

is made with Qcad 2, following the instructions from the old post.
Open it in Qcad 2 and you see what is meant.
Just in case, here is a screenshot:

Opening it in Qcad 3 does not yield a usable result, neither did fiddling around with patterns, scales and angles.

So... How do I do that in Qcad 3?

Pattern offsets are not supported by QCAD at this point. The best solution I can think of is to use two different patterns that are defined as being offset by 50% from each other.

That is what I wanted to do, but I found it impossible to add a pattern.
I researched the .pat file format and created these two (named _general.pat and _general_offset.pat) in the D:\QCAD Professional\3.1.2\patterns\metric directory
Code: Select all
*_general,general purpose solid line
0,   0,0   0,5
and
Code: Select all
*_general_offset,general purpose solid line with offset
0,   0,2.5   0,5
but even after a restart of Qcad3 these do not show up in the list of available patterns when creating a hatch...
What am I missing here?

*edit:
:idea: COMMA's, seperating the line offset from the line origin parameters.
:oops: I knew it was something blatantly obvious...
