PRIMER 22.1
Exclude Part
Exclude
By default PRIMER will apply the cutting plane to all the Parts/Part Sets in the model.
This option can be used to exclude individual Part/Part Sets from the cutting plane so they can be seen on either side of the plane regardless of the +ve and -ve action settings.
Here is an example showing some structure cut by a section.

By selecting some parts to be excluded from the cut section they can be made visible.
