Hi

If I create a sketch pattern, is there a way to keep its definition (in the form of constraints) after it's been created?

For example, when I create a circular pattern I specify the centre of the circle.  Once I've finished creating the pattern, the patterned elements can be dragged/moved such that the circle of the pattern is no longer at the point I specified when I created it. 

Is there a way to constrain the centre of a circular pattern in the same way that you'd constrain the centre of a circle, for example?

(I realise that there are workarounds - e.g. I could create the pattern manually using construction geometry and dimensions - I'm just asking specifically about the Circular Sketch Pattern command though).

Thanks a lot
