Why can't Basic Dimensions be specified manually?
Why do you have to use the Auto Dimension Scheme?
Becuase it's a known issue. SPR 405442 - 'Basic' tolerance type not available when adding dimensions using DimXpert.
Get your VAR to add to the notification of the SPR. The more people let them know, the quicker it will get updated.
In DimXpert you can't just arbitrarily select dimension and designate it as basic, you have to have your datums and tolerances established. DimXpert adds the basic dim automatically. Not the workflow I'm used to. I'm having other troubles trying to DimXpert this part.
