# pyoccad
A geometrical modeler based on the wrapping of `occt` (OpenCascade) open-source CAD package and helpers for a simplified use.
# History
## v0.6.0
*2024-07-12*
- Changed
- add `CreateCircle.from_radius_center_normal` and fix and deprecate `CreateCircle.from_radius_and_center`
- fix the `make_edge` helper, taking a single curve
- expose optimal algorithm to create a bounding box (`measure.shape.bounds`)
- refactor `create.solid` submodule and split surface creation helpers into `create.surface` submodules
- improve rendering by re-using the existing mesh (only update the buffers) and detecting object copies (using the `IsPartner()` method)
- add capability to do trimmed revolution in `create.primitive.revolution.CreateRevolution`
- fix unwanted copy when moving an object, to keep its existing tesselation and improve rendering
- Chores
- improve formatting and imports sorting using `black` and `isort`
- add `flake8` configuration
## v0.5.0
*2022-09-13*
### BREAKING
- Fix import errors due to API changes in `OCCT` `7.6` release (thus also `pythonocc-core`) (MR [#10](https://gitlab.com/cosapp/pyoccad/-/merge_requests/10))
- remove deleted handlers
- support API change to iterate over `Poly_Triangulation` nodes
- set dependency to `pythonocc-core` >= 7.6
## v0.4.2
*2021-08-31*
- Set dependency to `pythonocc-core` >= 7.4, instead of exactly 7.4.0 (MR [#2](https://gitlab.com/cosapp/pyoccad/-/merge_requests/2))
- New factory `pyoccad.create.CreateCylinder` (MR [#3](https://gitlab.com/cosapp/pyoccad/-/merge_requests/3))
- Replace `conda` by `mamba` in CI scripts (MR [#4](https://gitlab.com/cosapp/pyoccad/-/merge_requests/4))
- Minor refactoring pass (MR [#5](https://gitlab.com/cosapp/pyoccad/-/merge_requests/5))
