I'm making a template for a 3D printed jig for engraving parts repeatedly. I've created an outline of my part on one layer and I have my design I want engraved on a separate layer. Is there a way to “position lock” the layer with my part outline so I can not accidentally move it while adjusting my layers with the design into place. Similar to how you can lock layers in adobe illustrator/photoshop. It takes a bit of time to get the part outline into proper position and can be bumped so easily.
