Description

When you try to add allocation forms to some cut, you cannot do it and get the message:

Or (after Smart Normalize):

Possible reasons

Cuts, not belonging to the "Base Cuts" category, usually have a limited set of parameters. For some of them, the Goodwind cut engine is applied which extends the set of parameters - adds slopes. Thus, you can control more parameters for these cuts. 

There are some limitations to such cuts:

• Goodwin only accepts when 3 facets with 4+ vertexes converge at one vertex - more than 3 facets of such type are not accepted.
  
  
  
  Note Facets with 3 vertexes do not cause limitations.
  
  
• Facet types should be correct.

How to solve

1. To solve the 4+ vertexes problem, try running Smart Normalize. If this does not help:
2. Check facet types of your model.
