It seems that with a recent update to Fusion 360 something changed in the Manufacture section. I select Cutting 2D. Then select Razorcut45A from the library. All good, Next I try to select Contours under Geometry and go to the drawing and nothing highlights. The new version has geometry Selections, Chain Face Contours, pockets etc. Chain will allow me to select just a short line on the drawing but not the entire cutout. None of the other choices highlight anything on the drawing. Without contours selected I cannot generate the machine code needed to run the machine.
Is this something you have cut before? If not do you have a open line?
Good catch…It was a complex design and each cell and the perimeter had both or either very small gaps or double lines or small t’s off of the cut lines. Thank you so much…problem solved.
