Additional details on Slots
Slots and Open Slots
SA Supports the use of rounded slots, square slots, and open slots (or mid-planes) in the evaluation process. In order to use slots to define datums and checks they need to be manually identified in the annotation in order to be recognized in the evaluation process.
Marking a check as a slot triggers SA to search the surrounding sur- face faces for a representative slot feature. Only a single associated CAD face is necessary and additional face selections will only slow the search process.
