R@nSiD, I did what you said...but I have some questions.
First, why do you need to use the Freeze Transformation? What does it do?
After I used Freeze Transformation, I duplicated the polygon, set my value to -1, and then clicked combine...but my polygons didn't touch still...aren't they supposed to automatically connect?
Finally I went ahead it clicked merge, thinking they'd connect where I needed them to...only they turned white, and had yellow points all around them (I guess they're showing me their vertices?), but they still don't connect.
Am I using the Combine and Merge correctly? If so, then why aren't they connecting where they should? There's still a gap.
