Per Nick Sonders’ and others suggestion, I create my models over a few different files, pulling them altogether into one “master” file / model at the end. In order to keep everything in the correct location across these several model files, I create a reference plane for each XYZ direction. I create these in the first file, then copy / paste in place across the other files for the aspects of the model that I need. Everything gets positioned through reference to these planes.
When I create a component, I use component attributes to lock its position in the XY (and sometimes) Z planes. However, if I copy this component and then paste in place in another file, these locked attributes are no longer locked. I go to the component attributes dialog and the X and Y coordinates still exhibit the equals sign at the start that typically locks them in place, but the component can still be moved.
Anyone know why these components don’t stay locked in place in this manner?
