How to disable NORMAL constraint

How to disable NORMAL constraint

Hi, everyone, I found the Normal constraint in the Creo assembly very annoying, I don't want to use it at all, but seems it is the default Constraint, everytime I choose two surfaces, Normal constraint comes out, so I would like to know if it is possible to disable the Normal constraint, or change the default constraint to Concident?Normal constraint.PNG

There are is a config option related to the angle for which a normal constraint applies by default which can help, though just picking Coincident first will avoid it.

see:

comp_normal_offset_eps

Specifies the angle epsilon such that if the desired surfaces are equal or less than the epsilon (in degrees), then a normal constraint will be created (default is 10 degrees)

I expect that when you first add the model you will see that the surfaces start close to normal in the default orientation.

Perhaps a negative value will disable it?

Hi, dschenken, thanks for your replying, it worked unless the angle is 90 degree.

Hello zhihong li

l´m almost sure, there is some hidden config.pro option for this demand. Try to search following link with all hidden options.

Search Pro/ENGINEER config.pro options

Personally have found nothing useful for you

Let us know if you will find some config.pro options.

I haven't seen the normal constraint in years.

  Re: Assembly constraints

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

As l discovered, there are 3 config.pro options familiar with this problem.

1. auto_constr_always_use_offset --- control whether auto constrait should create offsets.

     YES - Auto canstraint always creates offsets

     NO - Auto constraint snaps align or mate if surfaces are within tolerances

     NEVER - Auto constraint never creates offsets

2. comp_angle_offset_eps --- Specifies the angle epsilon such that if the desired surfaces are equal or greater than the epsilon (in degrees), than angle offset constraint will be created.

3. comp_normal_offset_eps --- Specifies the angle epsilon such that if the desired surfaces are equal or less than the epsilon (in degrees), than angle offset constraint will be created.
