I will try this, the L shape is simply a font I downloaded and I have been using that font to make 3D printed items but sometimes when I extrude logos or random shapes, it rounds edges like above rather than just simply extruding exactly what is there. Almost like it's trying to fix itself or something.
Typically I take a logo or shape and cut out all around it or take a PNG image and just "3D Extrude" layer and it seems to be a gamble whether it will work right or if it will round and re-shape some parts of it. I have never used the "work path" like you mentioned above so maybe that is my problem. Will come back after i try it.
Thanks for the help.
Making a path often works best as you can keep the path nice and clean, which in turn leads to a clean extrusion.
