| Knitting tolerance |  | Controls which gaps are knitted closed and which remain open. Gaps sized below the tolerance are knitted closed. | 
| Show gaps in range |  | Displays only gaps within the range.   Drag the sliders to change the gap range. | 
| Knit  all gaps less than Selected_gap_value |  | When selected, closes the gap and all smaller gaps.  Closing a gap increases the tolerance.  | 
| Keep all gaps greater than Selected_gap_value |  | Indicates a closed gap. | 
| Decrease Tolerance to Selected_gap_value |  | When selected after right-clicking a closed gap  ,   decreases the Knitting tolerance to the gap value.  Gaps of value larger than the selected gap are opened and smaller gaps remain closed. | 
| Increase Tolerance to Selected_gap_value |  | When selected after right-clicking an open gap  ,   increases the Knitting tolerance to the gap value.   Gaps of value smaller than the selected gap are closed and larger gaps remain open. | 
| Zoom to Selection |  | When selected after right-clicking a listed gap, zooms in on the gap in the graphics area. | 
| Gap |  | When selected from the gap list, indicates the gap on the part. The value of the gap is the maximal separation.
