Side slope annotation

Hello everyone,

I'm having some problems with side slope annotation. So this is what i have done : 

* I created a new plan/linear3d Group Annotation

* I added a Side Slope Annotation entry

* I wrote the feature definitions in the Features text box

* I chosed the new "d annotation group to the proper feature symbology

However, when I tried to annotate the element, nothing appears.

Do you have any solutions ?

Best Regards
