Real value placement failure (iFeature debuging)

[Maxim-CADman77]

I'm keep getting error on attempt to apply iFeature that was extracted from real model and I want to know how to debug such situations.

Detailed description of the error

Window Title:

Autodesk Inventor Professional - Place iFeature (Consolidated)

Window content:

(!)Failed to place iFeature

   (!)Variable name contains invalid characters.

   (i)Real value placement failure

Any ideas?

PS: Just in case iFeature is attached (almost same as in standard tutorials).

Space char in Feature name occured to be root of the issue
