Let me reiterate, the logo was a logo of mine that I created in Carbide Create. It is nothing more than lines and toolpaths. However, when I created it I was in another file that had a bunch of layers in it. When I imported this into its own file I neglected to delete the layers and they have grown exponentially throughout several files I have imported this into now.
Click on the ellipse (3 dots) for the layer in the show layers dialog and select delete layer. With the large number of layers this file has it took a long time but did remove the first Minnesota layer when I gave it a try. I’d expect the speed to improve as the file has fewer layers.
