Intergraph Smart 3D


Selects an existing geometric construction object, such as a curve or surface, to edit or delete.


Selects geometry that defines a new geometric construction. This option is used with the numbered step options listed below.


Deletes a selected geometric construction.


Cancels the macro, closes the geometric construction ribbon and the Geometric Construction Palette dialog box, and then returns to the main command ribbon.


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, recently-used 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.


Specifies a coordinate system used to orient the line and define the plane of the line.


Specifies the starting point of the line.

Specifies a reference line. The angle of the line is measured from the reference line. If no reference line is selected, the angle is based on the coordinate system axes. This value is optional.

Specifies a tracking point used to control the direction of curve placement when an ambiguity exists. The tracking point is used with the value selected by Track Flag. This value is optional.

The selected tracking point must be an existing point previously created with Insert > Control Point, Insert > Topological Points, or other geometric construction point interfaces.

Color Coding

For a new geometric construction, you can identify the status of input items by the background color of the step:

  • - No background color when there is no input.

  • - Yellow background when an input is selected.

  • - Blue background when an input was selected for the previous geometric construction. The input can also be used for the current geometric construction.

Selected inputs display highlighted in pink in the Workspace Explorer and as pink dotted lines in the graphic view:

When changing an existing geometric construction to a different definition, colors represent the different value changes:

  • and - No background color when you keep the value of the original geometric construction.

  • and - Yellow background when you change a value.

  • and - Blue background when the software changes a value to a new suggested value.


Clears the selections for the current step.


Accepts the current selections and displays a preview.


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.

Active Axes

Defines the coordinate system plane on which the line is placed. Select (x,y), (y,z), (z,x), (y,x), (z,y), or (x, z).


Defines the angle of the line about the axis normal to the plane defined by Active Axes. If a reference line is selected for , then the angle is measured from that line.


Defines the length of the line.

Track Flag

Controls how the tracking point is used when an ambiguity exists. Select Near to use the curve nearest to the tracking point. Select Far to use the curve farthest from the tracking point.
