I had the realization that a python script could take all your strike and dip data, project the strikes out some distance from each point, intersect a cross section line, find the apparent dip using the dip attribute from the S/D feature class, and provide distances along that section line to each projected strike along with apparent dips in a table. I do believe that a QGIS plugin that does this would be extremely handy. Heck, it might be handier yet to allow extracting a topographic profile along that section line too.
Sounds like a good winter project. And it would save a load of time later on.
