PythonSCAD v0.16.0 Released

Hi everyone,

We're happy to announce the release of PythonSCAD v0.16.0! Here's what's new:

2D Object Properties

The .size, .position, and .bbox properties now work on 2D objects (square, circle, polygon, spline, etc.) -- not just 3D solids. For 2D objects, .size returns [width, height] and .position returns [x, y], while .bbox returns a translated square matching the bounding box. 3D behavior is unchanged.

s = square([10, 20])
print(s.size)       # [10.0, 20.0]
print(s.position)   # [0.0, 0.0]

c = circle(5)
print(c.size)       # [10.0, 10.0]
print(c.position)   # [-5.0, -5.0]

Colormap Support for GCode Export

GCode export now supports colormapping, allowing you to map colors to laser power and feed rate parameters. A new machineconfig() function lets you configure machine parameters directly from Python, and the pymachineconfig library provides a convenient interface for this. The release includes example scripts for both constant and dynamic colormapping. This also fixes an issue where color() would incorrectly overwrite the alpha channel with the default value when no alpha was explicitly passed.

Concat Works for 2D

The concat() operation now supports 2D objects, not just 3D. Internally, this came with a nice cleanup -- the separate ConcatNode was removed and the logic was consolidated into the existing CSG infrastructure.

Stability Fix: Member Function Segfault

A segfault that could occur when using member functions has been fixed. The member function dispatch was rewritten using a cleaner bound-member-object approach, replacing the previous trampoline-based mechanism. Thanks to Matthieu Hendriks for helping track this down.

Downloads

Pre-built packages are available for Linux (AppImage, .deb for Debian/Ubuntu, .rpm for Fedora/RHEL), macOS (DMG), and Windows (installer and zip):
