pybullet: The collision shape problem of hole object

[haha58768]

Dear Bullet developers,

I want to check a collision problem between hole and shaft in pybullet. When I convert the 3D model to urdf style and import into the Pybullet, it could show the features but can't detect the hole. Following the instruction, I use V-HACD tools and create a nes obj file. It shows no hole.

My question is that can I add the hole in the urdf file and make the shaft in to the hole?
