Feature Relationship Question

[Jindy]

I have a first plane. I want to create a second plane by rotating/offsetting from first plane. Now I want to delete/modify first plane, but the changes I make on First plane should not affect the second plane that I created. Basically, I want to break the associtivity or reference for the second plane from plane-1 and make second independent. Can I do this ? Thanks.

I don't believe that you can. Essentially, you'd have a parent/child relationship that you'd be trying to break.
The question I have is, what are you trying to accomplish in the end?

You can change the definition of Plane2. If you change it such that it does not use Plane1, then you are fre to delete Plane1.

o.k. I make several concept part designs and assemblies. In some situations, when I change a design feature in a part, I end up loosing some of my parent features (like a plane). In some cases, I don't have alternate plane(s )to redefine the plane's reference (unless I create one). So, I was wondering whehter I can make SW understand and define the location of a current plane (from origin, etc) before loosing the parent plane from which it is referenced. Hope the question makes some sense. Thank you both for the immediate reply.

It sounds like the "parent" features you're loosing are actually children of other features. This is why you're loosing them. The only way I can think of to prevent that from happening, and this isn't guaranteed, is to only create new planes via the three standard planes and some type of construction sketches/points that are located on the standard planes. If you use concept geometry to define the location of an inserted plane, you'll lose it if you delete the geometry.
