Hi

circular reference loops, is that bad to have in a assembly.

I get the notification but dont know how to solve.

1 CIRCULAR REFERENCE LOOPS FOUND
LOOP # 1
Depth of loop is 3
Feature number 6 (SKETCH_1, id = 107)
in model ACHTERPLAAT_KRK refers to:
Feature number 5 (PROTRUSION, id = 39)
in model BUIS-ACHTERKLEP_KRK refers to:
Feature number 6 (SKETCH_1, id = 107)
in model ACHTERPLAAT_KRK - circle closed.

This is what I found in the crc file of the assembly.

I found bach all of the id numbers.

Now what to do?

Hear you

Chris

You need to look at your sketch_1, id=107 and see what references the protrusion feature in the other model. Could be a constraint, a dimension, or a use edge. You should not have external references to other models. I am guessing you created the sketch in an assembly and referenced something in the other part.

Christiaan,

Just adding a bit to what Dennis said about references. In your case it looks like you need to do this checking twice, since you have A depending on B depending back on A. Yes, it is a bad idea to have circular references, in particular, and any external references that aren't necessary or desired. So called top-down design techniques can take great advantage of external references, in a large variety of ways, but you really need to know what you are doing and what the resulting dependencies will mean for model independence, document management systems, etc.
