I'm trying to sketch a concrete stair where one side is parallel to the run direction and the other side is at an angle (aligning with the reference line). I've tried to enter sketch mode, but I keep getting errors. Plus I can't find any tutorials on the steps to follow. I want the bottom of the stairs to be smooth, not stepped.
- Is there an issue with the family type or run type?
- What are the steps for sketching this type of custom stair boundary?
