Some problems with using convertGeometry().

[jiangxiaoyuyu]

Sorry to bother you, but I found some possible errors with the convertGeometry() function while using ifcplusplus. In my understanding, this part is to find the set of grids that should have holes, and then subtract the set of holes to generate a new mesh.

1. Should m_meshsets be replaced with m_meshsets_open? 2.CSG_Adapter::computeCSG Performing grid subtraction does not seem to work.

On the left is the bim model and on the right is the obj file created with carve

It could be a bug in the obj export. It could be a bug in Carve. To find out, you can debug the code with Visual Studio for example. Or check the file with the example Qt Viewer.

This is the txt format of the ifc file，The part that performs csg compute doesn't seem to work example.txt

The order of the points was incorrect. After modification, the test passed successfully.
