Detaching Elements without resetting Normals?

Description

Hallo everyone,

I am currently working with CAD files and everytime I detach an element the normals reset themselves and look like a mess.
So I am in desperate need of a script that detaches Elements without resetting the normals. Does one already exist or could anyone here give this a try?

Thanks a lot for any help!

I use the following method: duplicate object, then delete selected polygons in first object, and invert&delete in second one. And all normals are safe.
I can share the script if you need.

maybe this helps (it helps usually after importing from rhino or Cad):

1. add normal modifier (to flip normals)
2. collapse to edit poly
3. select all faces and flip normals
