Contour a Massing Model

This tutorial presents a process of contouring solid models to extract 2D profiles. This is often useful for such applications as computing building metrics such as internal/external areas as well as various prototyping methods such as mold making and building complex shapes from laser cut contours.

Technique

  1. Compute the total number of slices required to fully contour the imported solids by extracting the total massing height from a bounding box and dividing by the slice size.
  2. Create planes along the vertical direction and stepping factor (origin z-coordinate) proportional to the slice size.
  3. Intersect each solid with the generated plane, collect and emit the multiple curves of intersection.
