Fusion
The following picture shows the corner of a actual house with the horizontal plane cutting through the brickwork just below the window frames. How do I draw the two vertical red lines representing the measured distance to the ground at two locations, one being the corner point and the other a bit further along the wall. The third red line joining the two vertical lines represents the slope of the ground (going down towards the corner).
I created the two ground points using the move/copy command from the two points immediately above using the z-axis movement.
Fusion 360 will let me add dimensional constraints anywhere in 3d space, but when I use the line tool it doesn't allow me to position a line end above or below the plane. I looked at numerous tutorial but they focus on extruded shapes for manufacture. This is just old school surveying where I'm trying to make a picture that reflects an actual thing that already exists.
