How to Change Placement Face of Existing Feature 1

[Drkwing]

Suppose, we have an extrusion feature already defined... The sketch of the extrusion is placed on a previously defined Datum Plane.

After a while, we wanted to change the placement face of the existing extrusion to another datum plane defined later on. How can we do this?

Thanks in advance?

Drkwing,
The first thing you need to do is to open up your model navigator and either move the newly defined datum plane prior to the creation of the sketch, or move the sketch and all of it's child features to occur after the newly defined datum plane. Once this is done, you can easily re-attach the sketch to the desired datum plane. The key is that you can't attach a sketch to a later feature in your model navigator... because in effect, the feature doesn't exist yet.
The first method is probably easiest, unless the new datum plane is associative to a face that's dependent on one of the sketch's children (you created the sketch, made and extrusion, and attached the new datum plane to a face of that extrusion for example)... in which case your kind of hosed unless you re-define the datum plane back to the datum csys or some other NON-child feature of the sketch.
Hope this helps...
