PiQ Lang

Programming with PiQ Lang

PiQ Lang is the language ParametrIQ designs are written in: a short, line-by-line language of values, variables, points and drawing commands. Every ParametrIQ CAD drawing is a PiQ Lang program, so anything you draw with the mouse can also be written, read and changed as text, and anything you write can be opened and drawn on.

It is declarative: a variable or a point keeps its definition, not a fixed value. Define a box's flap as FLAP=D/2, and it is half the depth however deep the box becomes; define a point from other points, and it moves when they do. That is what makes a design parametric.
