Feature Relationship Question

Feature Relationship Question

Feature Relationship Question

(OP)
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.

RE: Feature Relationship Question

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?

RE: Feature Relationship Question

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.

RE: Feature Relationship Question

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.
