Thanks again, JD,
Any tip that is related is welcome of course.
For just moving a polygon and leave anything else untouched, you have good results with the Toolmove, while the snapping point is not along the selection axis. Maybe I miss something, but in the moment I move the axis to the Polygon center to pick up that point, I have problems to move the Polygon along the axis previously chosen, and then catch a point in distance to that axis. With the demoed above, I don’t have that hazzle. I use a tablet with a pen set for the RMC.
If it works for you, great! Again, I might miss something. I don’t get always the results as with the snapping method discussed in the help menu, I guess the flipping axis arrow (when the axis is very close to the polygon) throws me off.
My best wishes
