By "draft mode", I believe you're using the DRAFTING workbench and you want to add a Section View to your drawing.
To specify an Offset Cutting Line with an exact shape, go to the 3D model and add a Sketch of the cutting line(s), and constrain it into position. Add the 34° constraint, along wilth the Horizontal constraint. Add other constraints as necessary, such as center of a hole.
Once the Sketch is defined, switch back to the drawing and create a new Section View. But when prompted to define the section lines, go to the 3D part window and select the Sketch instead. This will bring back your drawing, and you can finish creating the view as normal.
Beside being able to specify the exact shape of your cutting line, another benefit is the Sketch is constrained to your 3D geometry; if you move the hole or change features the cutting line is constrained to, the Section View will automatically update.
