Hello Kelvin ,
Thanks for the immediate response.The problem is that , for the easy movement of parts as a whole , I have a set of three planes , which are referenced to the standard planes , as a template , when I start my sketching . Now, whenever I create a new plane with reference to these customised planes I have created , they do not match the size of parts . But , of course, yes, when I reference the plane to a certain side of the part , they are fine. But I usually dont reference planes with any part features, but with custom planes only . Is there a way to tackle this ? Or is it too much of an asking?
