Hey folks. I imported a stl and scaled it up to 550mm x 3mm. I need to cut this up into 9 smaller pieces. I can’t really find a great way to do it. The best I can come up with is to put a bunch of rectangle shapes down and subtract them from the main mesh body over and over until I get each piece. It’s doable but time consuming. Is there a better way within sharp3d?

Convert your STL in Fusion to a STEP and it gets a lot easier after you import it to Shapr.
