It's a zoom level bug, normally i zoom in max and 1 step out again, and then it is about 90 % to big in X and Y, Z is correct i believe.
It is fixed in the latest builts of TC, but the problem is they have not published an update or something of the Plugin itself, so until they do the tool is more or less useless.
