ST-Developer Merged CAD Library

Sample Programs

UPDATED! Now creates simple Brep boxes! Create a product with the common STEP structure needed to get started with geometry.

Construct an assembly relation between two products, relating the product structure and geometry.

Analyze the products, shapes, and relations in a file to identify the assembly structure. Walk assembly and print key objects.

Read an existing data file with geometry for a block and hole, then apply dimensions, datums, and tolerances to the faces.

Create a round hole feature with the parametric description (circular profile swept along a linear path) and a flat bottom condition.

Create a product with the common STEP structure needed to add descriptive and measure properties.

The ST-Developer Merged CAD Library makes it simple to build one program that can read or write any STEP CAD model. The library has C++ classes for everything in the original AP203, AP203e2, AP214e3, and the most recent version of AP242. Your programs can read files from any AP and switch between APs when writing. The library automatically handles deprecated entities for APs and needs no support files.

The Merged CAD library is called stpcad, and is installed as shown below:
