True Plan of a sloped Triangle

[tgray]

I have to create a cutting schedule for stone cladding capping on a sloped 3 sided wall.

I have a non true view of the plan and elevations to match but for the life of me I cant figure out how to get the true plan of this

What exactly do you mean by true view?

Looking at the slope at a perpedicular/parralel angle.

Draw the 1115 distance, then draw 2 circles with the length of the slopes next to it and connect their intersection point. You can also draw it in 3D if you have full autocad.
