Select
Selects an existing geometric construction object, such as a curve or surface, to edit or delete.
Add
Selects geometry that defines a new geometric construction. This option is used with the numbered step options listed below.
Delete
Deletes a selected geometric construction.
Cancel
Cancels the macro, closes the geometric construction ribbon and the Geometric Construction Palette dialog box, and then returns to the main command ribbon.
Close
Verifies the validity of values selected for the options, closes the geometric construction ribbon and the Geometric Construction Palette dialog box, and then returns to the main command ribbon. The selected values are still available when you click again on the main command ribbon.
Geometric Construction
Displays the current geometric construction interface. You can also select:

A different, recentlyused interface.

More  Opens the Select Geometric Construction dialog box. For a new geometric construction, all interfaces delivered with the software are available. For an existing geometric construction, only similar interface types are available.
Geometric constructions displaying only in the Select Geometric Construction dialog box are not intended for general usage. You should first consult your Intergraph support representative before using these geometric constructions.
1
Specifies the first curve.
2
Specifies the second curve. This curve must be connected to the first curve.
3
Specifies the surface onto which the curves and the fillet are projected. By default, this is the surface of the plate selected for the main command.
Reject
Clears the selections for the current step.
Accept
Accepts the current selections and displays a preview.
Continue
Completes the geometric construction definition. The ribbon continues to display so that you can define parameters for additional geometry.
The geometric constructions are not created and saved to the model until you click Finish on the main command ribbon to create the model object.
Radius
Specifies the radius of the fillet curve.
Projection Method
Specifies how the curve is projected to the surface. Select one of the following:
Normal  Projects the curve normal to the surface.
Along x  Projects the curve along the xaxis of the selected coordinate system.
Along y  Projects the curve along the yaxis of the selected coordinate system.
Along z  Projects the curve along the zaxis of the selected coordinate system.
