Follow your advice and the folder is now in .eteks.
I have to explain how this come about.
After you help me with plugins>AdvancedEditing.sh3p all was right the “Connect Walls” was
working until the other day after starting SH notice “Connect Walls” was shaded, try to find
why was unsuccessful I fill a new thread that was not answered, continue to find the problem change from ver. 4.5 to ver. 4.4 still the same, as I understand SH generates the folder sweethome3d from .eteks decided to delete the folder and reinstall SH this is the cause I fill a new thread.
To continue I would prefer with your guidance please.
Thank you
