For strapless garments, the armhole gape dart, the neckline gape dart and the Center Front gape dart are all rolled into one big gape dart. Note that this is using the Sleeveless Block. If you are using the Sleeve Block, you will also have to include the armhole gape dart.
If you are unsure how to merge these three darts (or any number of darts) into one, see the Manipulating Darts section of the Principals Menu.
See the image below for an example of the three gape darts merged into one.
