is there a way to get the dimensions (bounding-box scale) of a selected part of a mesh? Right now I have to do the following steps to get that information:

  • duplicate the selected part of the mesh
  • part it
  • switch to object mode
  • select the new object
  • finally read the dimension in the right bar
  • delete the object (cause I don't need it anymore)
  • select the other object again
  • switch back to edit mode to continue work ...

Since I have to do this very often I would welcome a shortcut or something ...

EDIT: the addon presented here comes close to what I'm looking for. Unfortunately the panel closes every time I change the selection and has to be reopened via menu ... Many thanks

  • $\begingroup$ just write a script that does exactly what you do and output the dimensions in console. $\endgroup$

I think this should help. when you are in edit mode, turn on this edge/face infos from the N key menu. this will show the scales of the parts you select.

  • $\begingroup$ Hello Ashok, thanks for you help but this shows the individual edge-lengths. I guess I wasn't precise enough. The information I'm looking for is dimension of the whole selection (the bounding-box for the selection). $\endgroup$
