The -p option sets the mirror point. By default, this is the global origin (0,0,0), as you noted in your mirror.txt writeup. You mirror across a plane, which is defined by a point, a direction, and a offset distance. Specifying the -x/-y/-z options is simply a shorthand for the corresponding -d direction vector. If you specified a -p point that was the geometric center of the object, the object would effectively flip "in place" in the direction you specified (assuming you don't specify a -o offset)." Ok, I summarized this into the man page and converted it to the xml using template and some other man pages (attached). Nevertheless I think there is something wrong, or I do not understand it correctly. See attached database mirror.g. The center point of the reg.r is at 15 5 0 (top view, ignoring z coordinate). When trying to do the flip you just described I would use command "mirror -p {15 5 0} -d {1 1 0} reg.r reg.r1", but resulting object is not rotated around the 15 5 0 point. " > Also I have noticed, there is no man page*, so I created raw concept (attached) which I would like to get done a convert to standard man xml. (If it is desired of course.) Desired? That's awesome. There's a blank template you can follow in the source tree (mged_cmd_ template.xml) that might help, or you can follow any of the existing examples. Cheers!
