Sketch Plane References
When you delete a parent feature that has child features built from
sketches, you have the option to keep the child features and have the
sketch plane references dangle. You can dangle a sketch plane reference
by editing the sketch plane definition and removing the plane definition.
To create dangling sketch plane references:
Select a parent feature that has a child feature.
The child must be a sketch-based
child, and the sketch must be dependent on the parent.
Press the Delete
key.
In the dialog box, clear Also
delete all child features, then click Yes.
A message warns about the problem and prompts
you to ignore the error or stop and repair the error before the software
rebuilds the subsequent features.
Click Continue
(Ignore Error) or Stop and Repair.
The What's
Wrong dialog box indicates that there is a sketch warning.
Click Close.
In the FeatureManager design tree, the part
icon, the child feature, and the sketch used to create the child feature
display warning icons that indicate
the sketch plane is missing.
You can use the Edit Sketch Plane
command to replace the reference plane.
