Hello everyone,

Trainee Here! Im trying to simulate a slit lamp illumination design which is used in slit lamps.

But im having problem in 2 subjects: 

Firstly, I cannot add the STL CAD part -which is imported from solidworks-, on the center of the lightpath. Im having a geometry error.

 Attachment 1 demonstrates it. There are 4 lenses and 1 detector. Slit is between object 2 and 3 .

The error I get when i set the Y axis position to 0:

Attachment 2 :

Secondly, I cannot import the human eye model which is a ZOS file . Attachment 2 .

Waiting for feedbacks. Have a nice day !
