RLCAD: Reinforcement Learning Training Gym for Revolution Involved CAD Command Sequence Generation

Understand

A CAD command sequence is a typical parametric design paradigm in 3D CAD systems where a model is constructed by overlaying 2D sketches with operations such as extrusion, revolution, and Boolean operations.

• Although there is growing academic interest in the automatic generation of command sequences, existing methods and datasets only support operations such as 2D sketching, extrusion,and Boolean operations.
• This limitation makes it challenging to represent more complex geometries.
• In this paper, we present a reinforcement learning (RL) training environment (gym) built on a CAD geometric engine.
