[LDCad] Part Snapping missing/errors

[Philippe Hurbain]

6587 (axle 3 with stud) snapping currently uses an axle meta with round section to make the stud. But this is wrong since the axle meta forces orientation of plate/tile placed on stud (moreover the hole in stud is not modeled).
Correction:

Code:

0 !LDCAD SNAP_CYL [gender=M] [caps=none] [secs=A 6 58   R 8 2] [center=true] [slide=true] [ori=0 -1 0 1 0 0 0 0 1]
0 !LDCAD MIRROR_INFO [baseFlip=Z] [counterPart=self]

instead of

Code:

0 !LDCAD SNAP_CLEAR
0 !LDCAD SNAP_CYL [gender=M] [caps=none] [secs=A 6 58   R 8 2   R 6 4] [center=true] [slide=true] [pos=2 0 0] [ori=0 -1 0 1 0 0 0 0 1]
0 !LDCAD MIRROR_INFO [baseFlip=Z] [counterPart=self]
