Since I was having trouble with the engrave operation (I'll explain that shortly) I decided to use the profile edges operation, and select the edges of each letter manually. I selected the interior of each letter and created a pocket so I had selectable edges. Now that I had edges, that was resulting in a huge list, so I broke it into groups, 1 per word, to make it manageable.
Engrave operation problem: I created a shapestring in the draft workbench, and used the 'convert between draft and sketch objects' to create a sketch that could be selected when creating the engrave toolpath. However, I get an error: 'Document.cpp (3462): Failed to recompute unnamed engrave: Part.BSplineObject has no attribute 'Axis' so I am stuck.
By the way, I can't copy text out of the report view
I hope this clarifies why I did what I did.
Thanks for your help and advice,
