- Several bug fixes on reader and PMI
- Several enhancements related to memory leaks and PMI

SolidWorks

## Enhancements

- The HOOPS Exchange API will now avoid splitting parametric surfaces. You can now compute parametric curve that cross periodic surface boundaries. The result is better performance and a better overall model, as the topology of the B-rep doesn’t change (previously, a split could cut a cylinder in two half cylinders).
- There are general improvements in performance and quality with our `AdaptAndReplaceAllBrepInModelFile()` function.
- HOOPS Exchange is now about to detect degenerate surfaces or continuous surfaces. See API functions `A3DSurfIsDegenerated()` and `A3DSurfIsG1Continuous()`.

- HOOPS Exchange now offers a function to compute hidden lines, A3DComputeOrthoHLROnModelFile.
- A new function, A3DMiscGetBoundingBox enables you to compute the AABB of a native CAD file. This function works with the following formats: CV5, NX, JT, SOLIDWORKS, Solid Edge, Inventor.
- HOOPS Exchange now provides the function A3DGetFileInformation to get file information from CV5 or SOLIDWORKS files without the need to perform a full conversion.
- HOOPS Exchange now provides the function A3DExtractFileThumbnail to extract the file thumbnail image from CV5 or SOLIDWORKS files.
