This module allows you to:
- Perform pit optimization on a block model.
- Visualize pitshells generated by the optimizer.
- Project a polyline at a given anle and height
- Draw a ramp from toe polyline to another toe polyline
- Offset the ramp 3D polyline
- Make the crest polyline of a ramp
- Set the top cone point according to the pit top surface
- Fit a polyline to the topography.
