Surface Flatten: Increase number of mesh elements to enhance accuracy

Question asked by Jakub Kwiecinski on Mar 29, 2018

Hello!

 

I am currently using the Surface Flatten feature to 'unwrap' various cylindrical surfaces.

 

SW controls the number of elements used to execute the cylindrical -> planar transformation during the operation via the "accuracy slider".  Higher accuracy = more elements added to the surface.

 

Unfortunately, the surface models I am working with are sufficiently large with tight features such that I lose the desired accuracy as the model (surface) size increases.  (note that for some models, reducing to a generic 'repeating unit' is not possible due to its uniqueness).

 

So, I would like to know if is possible to increase the accuracy of the surface flatten procedure beyond what is possible with the accuracy slider?  (i.e. somehow modify the SW defaults).

 

A few screen-grabs below.

 

Looking forward to your feedback.

 

Thanks,

JK
