Issue Description
You have edited the angle of a Roof and the junction has not been updated in your Section.
Solution
When using Single Plane roofs, keep in mind that you will have to adjust and rejoin them whenever you make a change.
Follow these simple steps:
1. Move back to the floor Plan
2. Select the pitch line and using the Offset command, move both roofs' outlines away from each other to create a 'gap'.
3. Select one of the roof planes and then Ctrl-click (win) or Cmd-click (Mac) on the ridge line of the opposite plane.
4. Now do this in reverse; select the roof plane that has just moved into position and then Ctrl-click (win) or Cmd-click (Mac) on the ridge line of the opposite plane.
5. Both planes will now have adjusted themselves and the section will look clean again.
