Recently I do some test in rotation in GDML format and find some different between in Physical Volume and boolean solids . In Physical Volume, the rotation was defined as clockwise by the axis from plus to minus . But while in boolean solid, the rotation seems to be anticlockwise which was different with the rotation in PV.|
The example was as following. In GDML, a tube solid was define as rmax=3, z=300, and the related PV was defined in pos=0,0,0, rotate=14,0,0 (deg). For check the result, a box (2,2,2) was placed in (1,41,151). In this way, the tube was nearby the box . In another way as boolean definition, a intersetion solid was define as a big box and a tube rmax=3, z=300, placed in pos=0,0,0, rotate=14,0,0 (deg). Then a PV related to this boolean solid was defined in pos(0,0,0) and rot(0,0,0) . For check the result, a box (2,2,2) was placed in (1,41,151). In this way, the tube was far away the box which the tube seems to be anticlockwise rotated .
Is there any different between the rotation in PV and the boolean solids ?
PS: I am very sorry for not upload the pic and the GDML file, but I think the related data had been listed clearly.
