Description

The entities could be:
- Lines, including parallel lines
- 2D polylines, excluding parallel polylines
- All edges of a selected 3D solid
- Rays, including parallel rays
- Infinite lines, including parallel infinite lines

Note:
- Press and hold the Shift key when select the second entity to create a corner (radius = 0). The selected entities are extended or trimmed at the intersection point. The selected part of the entities is kept.
