Sets of 2D sections, called contours, can also be derived from solid or surface objects in any orientation, with a single click of the mouse. These contours are always parallel to each other and parallel to a reference plane, which can be any of the Cartesian (orthogonal) planes or any other plane having any orientation in 3D space. This unique feature of form·Z makes it possible to subsequently use the contours derived from one object as profiles or control lines for the execution of other modeling operations.

Two sets of vertical (parallel to YZ and ZX) and one set of horizontal (parallel to XY) contour lines are derived from the model of a cup.

Contours derived from a small bulding. Center: parallel to the XY plane. Right: parallel to an arbitrarily positioned reference plane.
