Hello,
In my project I have a multitude of circular pattern features (about 20). The problem is that one of the circular pattern features has an error in it where it does not show a small section of the circular pattern. I am not quite sure why it is happening because I have edited the feature, changing the number of features to pattern and also double checked to make sure that there are no “instances skipped”. I am sure it is just a computer fault but is there anyway I can make it show back up?
Thank You
