@David.Nguyen Thank you so much!

I think the key point is, if there are two identical and symmetrical lenses set (or doublet, triboulet) in the system,
when replacing them, make sure that they are also identical and symmetrical lens combinations.

In this condition, you can only replace the left one to stock lens, and just copy and flip for the right one. 

Maybe it is not easy to examine the system has identical and symmetrical lenses set.

For example, try to find if there are two surface has the same parameters but only radius has opposite sign, then we can say they are identical and symmetrical.

Please see the KBA for the detail informaion.

Great news @Yihua Hsiao 


It looks promising. Do we know the shape factor difference range?

a shape factor difference within a certain range


Looking forward to trying this new feature.

Take care,

@David.Nguyen  The shape factor difference range is not a open information in the help file.But I think it’s just a range, looks like 10%, 20%.
