I am not sure why it is being complicated that much!!!
Beams and Column (Namely concrete ones) Join automatically as you draw them (an innate property Revit give to these elements). If you want it to join elsewhere or differently all you need to do is:
- Set your reference planes Horizontal and vertical to create an intersections to refer to in the 3rd step
- Use Unjoin to remove the Join envoked by default to the beam and column
- Drag your beam to the intersection where you need it to join/cut
- Re-apply join to columns and beams
Note:
The beam needs to be withing the bounding box of the Column... if it is too high above the column; the Join tool will not extend neither the column nor the beam. You need to adjust that using the handle controls or by adjusting Hight of the column in the properties palette
