Evaluate Draft Angle wont work right ?

[webeber]

Hi there,

I've a problem with this function.

A plastic part needs analysis:

I've done the following steps:

1. Switch in the controlpanel to surf evaluation

2. Switch to vector > type in Draft angle

3. Pick the vector ( create before, normal to a surface )

4. update from selection  > but nothing changes, the numbers stays the same ?

What's wrong ?

Have anyone a advice for me?

Thanks
