Hi Earl,

The error message you are getting is usually a result of a parameter that causes SketchUp to attempt to draw a circle in space (where there is no face). Most often it is because the user made the depth of the cabinets more shallow but failed to change where the back shelf holes are drawn. If you send your .skp file to me at jpz@srww.com I will look at the problem and tell you what you have done wrong.
