I want to put a cutting plane line through a feature. This will be generic/template drawing, so when the feature moves, I want the cutting plane to move with the feature. When I start the section view, it asks me to click to place the cutting plane. If I click to anchor it to geometry, it only lets me select solid vertices. But I want the section to go through the middle of the feature, and not the edge. More importantly, there's another feature that comes and goes, and when it goes it wipes out the vertex that I had selected for my cutting plane.
It doesn't appear that I can put a section through reference geometry. Is that correct? Are there other ways to accomplish this?
