I've activated the Mesh-3D printing Toolbox in Blender. But the tab doesn't show up in the tool shelf. Please help, a bit urgent.

Thank you

  • $\begingroup$ I refreshed, saved user settings, disabled, enabled again (nothing disappear, or appeared), saved user settngs again, everything. Also, when I close and reopen the program, the addon is still enabled, but no tab in the toolshelf. $\endgroup$ Nov 26, 2016 at 17:24

The panel for the 3D printing tools is only visible when the active object is a mesh object. The active object is the one highlighted in a slightly lighter colour (depending on the theme used).

There are times when an active object can be deleted or deselected without a new object being set as active, usually this happens using the outliner or a script.

Change your selection or ⇧ Shift select one of your selected mesh objects to make it the active one so that the panel shows up.
