Inserting short distance nodes creates a “Cannot complete…check min/max constraints” and when you click OK the command finishes and you need to restart it. Once you click OK the inset node should still be active, eg. return to previous state and allow you to choose a different location for the node, that doesn’t create an infringement. I can’t tell by visual inspection if I will create an infringement (especially when working in isometric, perspective) so keep my command active and allow me to choose a different location.
