How to clip shapes out of outlines

Question

Hey guys, so, I have a stroke of a circle, and I want to clip a shape out of the edge:
When I use the parallelogram as the mask, I get this:
When in fact, I want the inversion of that:
I mimicked that by just making the parallelogram white, but how would I do that using clipping masks?

Answer 1

theorange,
To do it with a Clipping Mask, you will have to do it in reverse; you may:
1) Create an object at least as large as the object to be clipped (a large rectangle will do);
2) Select the large object from 1) and the shape you showed in the OP image, then Object>Compound Path>Make;
3) Use 2) as the Clipping Path for the Clipping Mask.
The Opacity Mask is somewhat easier for a case like this.
This is because the Clipping Mask can only show what is masked, whereas the Opacity Mask can both hide and show, and even make transitions in between the two.
Hi Peter. Still no show here.
