[LDCad] Part Snapping missing/errors

[Stefan Frenz]

I have problems with part-snapping of roller coaster tracks on top of other parts, i.e. 25061 (90 degree), 26561 (ramp), 34738 (S-shape), 26599 (S-shape lower)... They snap perfectly "under" another part, but not on top of it - so I let them snap below and move 2 plates (16 LDU) upwards. I don't know if this is my fault or if the parts are missing snapping info.
