This is not correct. Functions can be redefined by (re)loading Lisp files. So it is the function definition from the Lisp file that was loaded last that will be used.

If I wanted to do this somewhat predictably, I might do something like this. Draw a rectangle or other polygon in Modelspace to essentially frame the view or Objects in question. If you later move or create a new viewport, double click inside of it to activate it, then use the ZOOM command with Object commandline option, and choose the frame which you created. It will zoom to fit, don't forget to check your viewport scale and lock the viewport. As long as you move the frame with the object, you should be good.

Don't misunderstand, I wasn't telling you not to try it. I don't know enough about your scenario to have an opinion about that. Someone else here may have a better, more elegant solution that does exactly what you want.

It is possible to create a view object that is linked to a viewport. It is possible to add various objects to a group. If you grouped a view with your block, you might be able to do what you want. Just spitballing here. Of course, this gets hideously complex in a hurry. What happens if there are two blocks and you move one? What if the items aren't coplanar? How do you manage viewport scale? Good luck.

how about .PSLTSCALE (note the . at the beginning) to get the non-translated command? Or _.PSLTSCALE which should do the same. I recently had to work on a French AutoCAD - had to use dots before every command!

Donuts dont exist long I just ate the last one. Oh yeah a donut is a Lwpolyline.
