Antimony

Antimony is a computer-aided design (CAD) tool from a parallel universe in which CAD software evolved from Lisp machines rather than drafting tables

foundations Antimony is built on three mostly-orthogonal axes: A framework for tracking information flow through directed acyclic graphs A geometry engine for doing CSG A standard library of shapes and transforms Graph engine Solid modeling in Antimony is done by connecting nodes in a graph.

Features:

• Dramatic speedup in mesh export
• Added experimental feature detection to mesh export (which finds edges and corners and pushes a vertex to keep them sharp)
• Another major speedup in loading large files
• Made export workflow more flexible:
• In the graph view, create a node from the Export node category
• Attach shapes to its inputs
• Click the small arrow in the upper right of the node to run the export task
• Added 'Jump to node' on right-click (in either 3D or graph views)
• Improved documentation

Bugfixes:

• Fixed a few memory leaks of Python objects
• Cancelling an export with Escape now actually stops the export task
• Changed the way that images are drawn to prevent (?) QGraphicsScene crashes
• Removed multisampling to fix crashes on Yosemite with integrated GPUs.
