Automatically add cordial constraint when sketching circles?
When adding circles that need to be equal to a past circle (edge or sketch) SolidWorks will snap to that circle but will not fully constrain the circle. The best ways iv'e found around this is to make it slightly bigger/smaller, ctl + click each one and add the cordial or equal relation. Alternatley you can do a convert entities on the old circle, each way involves an extra step... anyone have a better solution?
are you referring to an assembly with multiple parts? is the circle a hole or a boss? id try fully define sketch, maybe hole series. hard to tell, otherwise your way works as well.
note: turn on automatic relations if it is not already, tools>options>sys.options>sketch-relations/snaps
