    I think it is easier to fill up a hole than to make holes, isn’t it? (I am kidding.)

    So now, you have a point or node as the center, and the diameter or radius. And I assume you wanted to make a hole on 2D mesh, not 3D mesh. What you can do is, make a circle which is a line. Then find an element most near the node, find it’s adjacent, and another layer of adjacent, etc. until the area is big enough than the hole. Then you re-mesh the patch with the line. Then you delete the elements within the circle.

    Test it interactively, and then open the command file to see what happened. Please let us know the method works.

    I think there is command to trim a hole in a mesh. If I remember correctly, look in the nastran panel. In the HM help look for 'Trim Hole Macro'
