This has been like practicing self dentistry - specifically a root canal.
OK where things stand right now. First off a huge thanks without the help I would have given up.
The problem is/was me. I didn’t realize I had to work with closed shapes, hence no adjustment with the many test cuts I made. 30 or 40 with small adjustments. The is a problem with my C01 layer - more in a moment on that. When I tried to duplicate the example above I used lines not noticing the pieces were rectangles, I am going to reconstruct that tomorrow, simply because I want to learn.
I mentioned above I had this working than I went in again and it didn’t work. That was because I changed the closed shapes which opened the shapes. I continued to use the open shapes with a huge amount of testing resulting in a total waste of time/material.
The acrylic I am using is 2.97mm, the kerf being 0.22 and the setting for each piece is 0.11 resulting in a very tight fit.
… If I combined both images on on 1 layer and set the kerf to 0.11 (1/2 of Kerf) would the result be the same as cutting on 2 separate layers with the setting at 0.11?
… Would the kerf work if I joined the two pieces as a single image with separation line/cut ending up with 2 pieces. The kerf setting would be set to 1/2 (0.11).
Problem with layer CO1. The odd shapes I showed above, rounded corners and tabs was caused by some setting(s) in my C01. Every rectangle I create has rounded corners when I preview the image.
Is there a way to reset a layer to LB original settings? It would appear I have set the current (wrong) settings to be default.
