What it can do

Creates native, parametric Creo features such as sketches, extrusions, revolves, holes, rounds, shells, sheet metal, blends and airfoils, keeping dimensions and references editable.
Builds assemblies and drawings, edits parameters and relations, and queries the feature tree.
Saves a new .prt or .asm version after each change, reloads it from disk and compares features, dimensions, volume and parameters.
Rolls back failed changes and protects against stale requests with revision checks; runs no arbitrary commands.

Limitations

Needs Creo's Toolkit SDK and the MSVC x64 C++ build tools to compile its executor, plus a PTC licence.
Documentation is in Chinese.
Not suited to free-form surfacing or full coverage of specialist Creo modules, per the author.
