As the title says, I don’t know if there was an update or what but I’m having solids completely deleted after I deleted a few lines from the 2D seed of those solids. What is going on? I tried to unlink the drawing but nothing works. Help?

Feature change with the addition of parametric modeling. Bodies are dependent on the sketches from which they’re created, so editing those sketches will affect the bodies. It’s a powerful feature once you get used to fully utilizing it, but if you want to disassociate the sketch from the body, you have to merge history.
