Properties
Opens the Properties dialog for the selected geometric construction. This option is only available after selecting an existing geometric construction.
Geometric Construction
Displays the current geometric construction interface. You can also select:
A different, recently-used interface.
More
Opens the Select Geometric Construction dialog. For a new geometric construction, all interfaces delivered with the software are available. For an existing geometric construction, only similar interface types are available. For more information, see GeometricConstructions.chm and CMNSTRGeometricConstructions.chm in the [Product Folder]\Programming\Help folder, available when Programming Resources is installed.
1
Specifies the profile or member system.
2
Specifies a plate system, profile system, or reference plane used as a sketching plane intersecting profile or member system 1.
Specifies a coordinate system. If no coordinate system is selected, then the main coordinate system is the default. This value is optional.
Creating
For a new geometric construction, you can identify the status of input items by the background color of the step:
- No background when no input is selected.
- Yellow background when an input is selected.
- Blue background when an input was selected from the previous geometric construction
and can be used for the current geometric construction.
Selected inputs appear highlighted in pink in the Workspace Explorer and as pink dotted lines in the graphic view:
Editing
When modifying an existing geometric construction to a different definition, the colors are used differently:
and 
- No background when the value of the original geometric construction is retained.
and 
- Yellow background when you change a value.
and 
- Blue background when the software changes a value to a new suggested value.
Multi-editing
When modifying multiple existing geometric constructions and an input or parameter is available for all selections:
- Blue background when the input is the same for all selected geometric constructions.
- No background with pink underline when the input is different for all selected geometric constructions.
- Blue background with pink underline when the input is different for some selected geometric constructions.
- Yellow background with pink underline when all inputs that were originally the
same have been changed. Remaining values have not been changed.
- No background and no text displayed when the value of the parameter is different
for the selected geometric constructions. Each value, along with the applicable geometric
constructions, are available as selections in the box, as shown in the following example.
Reject
Clears the current selection.
Accept
Accepts the current selections, and displays a preview.
Finish
Completes geometric construction definition. The ribbon is still displayed, and parameters for additional geometry can be defined.
Name
Specifies the name of the geometric construction.
Parent
Specifies a parent for the geometric construction. Select one of the following:
-
The current model. This is the default value.
-
More - Select a system in the model.
The New GC Set option is not used for topological points.
KeyPoint
Specifies a key point by index number. Every cross-section has 27 Key Points, although some are combined for cross-sections with simple geometry.
Select Value in the 3D Graphic View
Allows key point selection in the graphic view. Key Points display as preview geometry, key point numbers, and the local u-v coordinate system.
U Offset
Specifies the offset of the geometric construction point from the key point along the local u-axis of the cross-section. See Key Points.
V Offset
Specifies the offset of the geometric construction point from the key point along the local v-axis of the cross-section. See Key Points.
Offset 0
Defines the distance that the point is offset from the sketching plane 4.
Face Reference
Specifies the profile face to use to create a sketching plane. Select Web or Flange. This option is only available when a profile system is selected for sketching plane 2.
Direction
Specifies the direction of Offset 0, using the axis normal to the sketching plane. Select Positive or Negative.
