Hole pattern - symmetric about center hole in two linear directions

Ok...I thought I could do this, but I keep getting two holes in the center.

I've created the center hole and am trying to pattern one to the right, horiz, 100mm, and one to the left, the same distance, in the same command. I can pick the two directions and offset, but keep getting a duplicate hole in the center. Number of members in both directions must be two or I get an error.

I would think this can be done without getting a duplicate hole in the middle, but maybe not? If someone could shed some advise I'd greatly appreciate it!

There are a few things you can do with this. The first for the method you are using is to select the duplicate black dot at the center to remove it from the pattern. The only one that can't be removed is the pattern leader which has a circle around it. Other things you could do although they may not necessarily be what you want are a pattern table, diameter pattern, radial pattern, and pattern by point.

Well, since it's the pattern leader in two directions, I can't select the black dot.

There is only one pattern leader which is the one you select to make the pattern. You should be able to select the second one. Another note is that for a direction pattern you are not required to have a dimension specified in the dimension tab. It can make it easier for you to de-select the instance that is overlaid on the pattern leader though.
