Newbie question re Pcbnew version (5.1.5)-3 release build
I have a complex board shape on which I need to position mounting holes and several headers that will engage with other stacked boards in a very tight-fitting enclosure. It is essential that I position them exactly and then don’t accidently move them. Googling, I find people describing how to lock footprints in older versions (for just the reason I want to do it) but I can find no way to do so in the above referenced release. Is locking not the right approach? Is the terminology changed? How can I ensure my mechanical components stay locked in position with respect to the cut edges?
