Can I wirecut or use another tool to cut multiple identical shapes into my object at the same time

Hi @jamesc, usually you would extrude all curves with Solid=On to your desired depth, then boolean the resulting boxes from the main object. To make this in a single step, move the curves to the desired depth, select them and start the _Boss command. Then click on the front boundary surface to extrude and cut out in one go.
