I am having a hart time doing a spline Mask with a clone object. Here is how i set it up. I created a clone object with about 25 squares. I then created a circle, place both the circle and the clone in the 'Spline Mask" then selected "A subtract B" and nothing happens. I have to convert the clone to a spline, select all the splines, do a connect and delete then it works. In short can a clone work in a spline mask?
