Merge Points allows you to consolidate two points into one.
Select the point you want to keep. We will refer to this as the Keep Point below.
The selected point will turn blue. Now select the point that will be merged into the selected point. We will refer to this as the Merge Point below.
You have three options as to where the points will merge.
If you choose Keep Point, the merge point will be moved to the keep point position and merged.
If you choose Remove Point, the keep point will move to the remove point position and merged.
If you choose At Center, the keep point and merge point will be moved to the center between the points and merged.
