Surface -Surface matting in Constrain Type Automatic picks Normal as default option.

[Yogesh.T]

During Assembly when I pick surface -Surface it should be Coincident automatically not Normal. PTC needs to fix this OR let me know the benefit. 

This is very inconvenient additional multiple clicks which are not needed.

Its a setting you can change. I'm not sure why they would ever make it work like they do OOTB

For eliminating the normal constraint from happening by default:

comp_angle_offset_eps 91

comp_normal_offset_eps -1

Add this option to get it to default to coincident instead of distance:

auto_constr_always_use_offset never

Worked like a butter! Sweet.
