Sectional & Orthographic Views

Pick a solid, tilt the cutting plane and slide it through the shape. See the truncated solid in isometric, the top, front and side elevations, and the true shape of the section — all updating live.

Isometric (perspective) view

Section: Section = an ellipse (minor axis = 2R; major axis grows with angle).

Orthographic projections

Top view (plan)

Solid lines = visible edges · dashed = hidden edges · amber = the cut (section) outline. All three views share one scale.

True shape of the section

The cut face rotated flat to the page — its real, undistorted shape.
