[Gate-users] Gap in Hexagonal LEHR collimator geometry

[Khalid Hussain]

Dear gate users,

There are small gaps in the collimator geometry. The collimator is standard
multi hole LEHR collimator for spect camera. The screenshot of geometry and
script is attached.

Please check and help me where the problem is in geometry.

Thank you.
