Description
This tool creates an arc of parabola by focus, vertex and endpoints.
How to use
- Press the
Create an arc of parabola button. - Click in the 3D view to define the focus point (labelled 1 in the picture above).
- Click in the 3D view to define the tip of the arc of hyperbola (labelled 2 in the picture above).
- Click in the 3D view to define the first end point (labelled 3 in the picture above).
- Click a fourth time in the 3D view to define the other end point (labelled 4 in the picture above).
