When trying to use some sketches as the profile for a (loft)/(sweep)/(boundary Boss/Base) SolidWorks sometimes automatically selects the entire sketch (Figure 1) without showing the pop-up window (Figure 2) that would let you select only a portion of that sketch if you wanted to. How do I force SolidWorks to show that popup window?
I'm on Windows 10, SolidWorks 2017 service pack 2.0
