Cant find relation

[wildmodeler]

Model check is saying I have a relation error:

RELATION_ERRS
Relation errors exist in model: 1

d22 = d15 /* ERROR: Invalid symbol 'D15' found.

It is a small assembly 5 parts. List all the dimensions and there isn't d22 or d15. Cant find the relation anywhere! Any help finding this?
Thanks

My advice:
First, try to identify which part the error is in - the top level, or one of the 5 parts
Then, you may need to look at the relations in each feature, as opposed to just the model relations (first drop-down on the relations viewer allows selection of features)

Unless the features are complicated, I would guess that it would be third or fourth feature.
