Click Calculate Hoopings to evaluate the hoopings that will result from the current hoop layout. Bear in mind that a calculated 'hooping' is not necessarily the same as a 'hoop position'. The same hoop position may be repeated, depending on the object sequence.
Hoop placements which follow the object sequence will reduce the number of calculated hoopings.
The time taken to calculate hoopings depends more on number of objects and hoop positions than actual stitch count. Even with native EMB, if the design is complex, large, and contains many hoop positions, calculation can take time.
Designs converted from EXP, PES, HUS, etc, will generally result in a larger number of objects than native embroidery designs. These will take longer to calculate.
