This repository provides source data for our paper:

A History-based parametric CAD sketch dataset with advanced engineering commands

HPSketch is the first history-based parametric CAD sketch dataset to support advanced engineering commands.

A gallery of HPSketch dataset is shown above.

The vector format of HPSketch is in the folder of ./data.

Visualization and Export

We provide an online website to visualize CAD models.

http://whucad.l2.bb1a.cn/

Through the above web interface (without the need to install industrial CAD software), WHUCAD vector files in .h5 format can be processed. These may include vectors from the WHUCAD dataset itself, or vectors predicted/generated/reconstructed by AI systems based on WHUCAD vectors through relevant vector computation—for example, new vectors generated via GAN or Diffusion networks.

Three representative types of geometric models are supported (CAD / CAE / Visualization):

• stp (Brep) – CAD geometric models in boundary representation (B-rep) format.
• stl (Mesh) – Visualization geometric models in mesh representation.
• icem (ICEM) – Pre-processing geometric models compatible with CAE software such as Ansys.
