Action radio buttons - specifies the primary action of this function:
Create Hole radio button - a perfect hole will be cut at a location that you select on the object in the Viewing Area.
Fit Hole radio button - a jagged hole that you select in the Viewing Area will be refined to a round hole. Typically, use Fit Cylinder instead.
Fit Cylinder radio button - this function converts a jagged hole with or without cylindricity to a perfectly round hole with no cylindricity, or changes the radius of a round hole with or without cylindricity to a hole without cylindricity. This function is the same as Fit Hole, but also accomodates holes with cylindricity.
Radius field (a parameter of Create Hole, Fit Hole, and Fit Cylinder) - specifies the radius of the resulting round hole.
Adjust Normal checkbox - restores the normal of the hole to its previous position.

Datum Name field - specifies the name of the Axis Datum. This name will appear in the object’s Datums subfolder in the Model Manager
Create button - creates the datum. Datum Name appears immediately in a Datums folder under this object in the Model manager, even if you never press Execute to create or fit the hole.
Clear button - (clickable after you select the location of a new hole or click an existing hole in the Viewing Area, and before Execute is pressed) removes the selection of a hole or hole location and prepares for the creation or fitting of a new hole.
