Thanks Tig, adding the Font took care of the problem.

The item is a group.

I just installed v5.11 and cant get the plugin to slice anything. I checked the folder locations of all the files and everything is in order. I have SU v8, and tried slicing a simple solid box as a test, but no success. The Slicer menu shows up with all the commands but it doesnt work. Any help would be appreciated.

Once I click on the Hole on solid button I cannot selet the items. The selection arrow is shown but nothing gets highlighted or selected upon clicking. SU version Im using is 8.1.16.
