You can constrain a pattern using a geometric reference of the pattern relative to another geometric element or another pattern.
For example, we want to constrain the pattern of square pockets so it is parallel with the front face of the part.
|
|||
When we create the relation, we first select the pattern and a face, edge, or vertex on the pattern. We selected the green face.
We then select any face, edge, or vertex. We selected the yellow face.
The pattern’s position will be determined by the relation between these two faces.
|
|||
We created a parallel relation. When we update the relation set, the pattern moves so the Reference is parallel with the yellow face.
Follow
these instructions to create this type of relation.

Creo Elements/Direct Modeling cannot constrain a geometric reference of parts of a pattern.
|
You can also define the pattern’s position by constraining its origin.
|
|||
First we set up two relations to constrain the origin with a certain distance to the planar side faces.
Follow
these instructions to create this type of relation.
|
|||
Because we only constrained the origin to position the pattern, we can also constrain other pattern values.
We increase the length of the part using the distance relation for the length defined between the two faces shown in yellow. Another square pocket is added because we increased the length far enough.

This is our modified part after we update relations.
