NX Unable to specify a gap of the extension line for sketch dimension

After upgrading NX series, it is not possible to specify (change) the gap setting of the dimension extension line in the legacy sketch creation because it does not exist. Existing legacy sketch created in NX before upgrade can be set/changed. Is there any way to set it?

This is because the "Fixed Text Height on Screen" setting is set to OFF.

Not depend on new sketch or legacy, the availability of the Gap and Overhang settings in sketch dimension depends on the setting "Fixed Text Height on Screen". When this setting is ON, the Gap and Overhang will not be available in the dimension’s settings because the dimension’s text height will change as the view’s zoom factor is changed (Zooming in or out) and the gap and overhang are relative to the current dimension text height. When this setting of OFF, the dimension’s gap and overhang can be changed.

Not depend on new/legacy sketch, can be set with below.

1. File > Utilities > Customer Default > Sketch > General > Sketch Settings

2. File > Preferences > Sketch > Sketch Settings
