I have a few questions about the LDCad shadow library and the snap metas:
1. Grid with 6 parameters
I found this line in 71861.dat:
According to the docs, Xcnt would be 1 and Zcnt C 2. After that, there are still four numbers left (1 0 46 0), but there should only be two.
In LDCad the cylinders are moved in the Y-direction (along the axis of the cylinders), but I did not find any documentation about this. What does this additional parameter mean exactly? Is there an undocumented alternative [Xcnt Ycnt Zcnt Xstep Ystep Zstep] format?
2. Default of SNAP_FGR.center
According to the docs, SNAP_FGR.center is the same as SNAP_CYL.center. There, the default is false. But in LDCad it seems like the default of SNAP_FGR.center is true. Which is correct?
3. Matching of SNAP_GEN bounding shapes
How are SNAP_GEN bounding shapes matched? do they only match when they are the same type? In which cases does the orientation matter? How the groups work is clear, but the docs are very vague about the rest.
4.SNAP_CYL.mirror.cor
According to the docs, one of the radius axes must be flipped if the transformation matrix contains a mirroring and SNAP_CYL.mirror is set to "cor". How does that work exactly? Flipping a cylinder on any axis doesn't change its shape.
Thanks in advance for answering and have a nice day!
