Is there no way to create a linear fit hole pattern in SW. That is, place the first hole, define where the last hole is and fit a number of holes equally spaced in between. These images show this in another program to help illustrate.
In the example you have shown a Fill Pattern would probably work. Another option would be to create a Global Variable linked to the length of the dotted line, then use that Global Variable in an equation for your number of instances. See attached. If the length of the extrude changes then the spacing of the holes will change.
