In this section:How to create a Feature Point on a Surface? How to create a Feature Point on a Cylinder (Pin/Hole)? Other Parameters and Functions |
[Fast Point Creation]: Allows the user to create points simply by clicking on a surface. (See Fast Point Creation).
One Point: Create a Feature Point by specifying the U and V values (0-1). Feature Points associated with a surface have a U and V value which define their relative location on the surface. The U and V direction indicator will show on screen while points are being created. These Feature Points will have associated vectors that are normal to the surface.
Note: Feature Point vector directions are defaulted to follow the material direction, or normal to the surface. When Feature Points are created on a feature, 3DCS automatically determines the "outside of material" direction and defaults the Feature Point vectors accordingly. The user may still reverse the vector directions if desired using the Switch Directions check-box in the Feature Points dialog.
•As a Feature Point/Coordinate Point is created or modified, it is automatically displayed graphically while that point is active, regardless of whether 
Show Points is on or off.
Grid Points: Create a grid of Feature Points on a surface or cylinder by specifying the number of segments with the U Segment # and V Segment # input fields.
Center: Create a Feature Point on the axis of a pin or hole by specifying the V value (0-1). The V value defines the relative distance of the Feature Point from the base of the pin or hole.
Note: When a Feature Point is created at the center of a hole (internal feature) or pin (external feature), 3DCS decides whether the feature should be treated as a hole or a pin based on the nature of the feature itself.
In U-Dir: Create a set of Feature Points along the U direction line by specifying V Segment # input field (1-100) and the U value (0-1). The V Segment # defines the number of segments in the set of Feature Points and the U value defines the relative distance of the set of Feature Points along the U direction line.
In V-Dir: Create a set of Feature Points along the U direction line by specifying U Segment # input field (1-100) and the V value (0-1). The U Segment # defines the number of segments in the set of Feature Points and the V value defines the relative distance of the set of Feature Points along the V direction line.
[Select Feature]: Prompts the user to select a feature to be used in the Feature Point dialog. The selected feature may be renamed in the field next to [Feature].
Note: The user may select a feature before initializing the Feature Point dialog. When the user selects 
Feature Point with a feature already selected, the selected feature becomes the active feature for creating or modifying Feature Points.
[Create Point(s)]: Create the active point(s) from the Feature Point dialog. The user can then continue to create points, or [Close] the dialog.
Note: If a Point already exists at the UV location, creating another point at the same location is .
[Delete Points on Feature]: Delete all Feature Points on the active feature.
[Create Points on Mesh]: Create Feature Points at all of the intersecting points on the surface mesh.
[Create Surface Center Point]: This option will quickly create a point at the center of a surface, or along the axis of a Cylinder. This is the only option when creating a point in the center of a planar surface. Using the UV values at 0.5 and 0.5 will not apply a point at the center.
[Select Point]: Prompts the user to select a Feature Point/Coordinate Point to be used or modified in the Feature Point dialog. The selected point is now active and may be renamed in the Type-In field next to [Point]. The U and V field will display the values for the selected point.
•Users can use the Window selection (selection trap) to select multiple points.
•Users can use Shift+Mouse click to select 1 or more points in the Model Navigator.
•All of the points will be shown in the list below [Select Point].
[Project on Feature]: Projects all the Feature and Coordinate Points in the drop-down list onto the active feature
Note:
•If the Move Original Point option is unchecked, new Feature Point(s) will be created on the active feature with no links to the MTMs (Moves, Tolerances, and Measures) of the points they were projected from. Any Coordinate Points in the drop-down list will be converted to Feature Points.
•If the Move Original Point option is checked, the Feature and Coordinate Point(s) in the drop-down list will move to the active feature as Feature Point, maintaining links to MTM’s. Any Coordinate Points in the drop-down list will be converted to Feature Points.
[Convert to Coordinate Point]: Convert all the Feature Points in the drop-down list to Coordinate Points.
[Apply Changes]: Apply the requested changes for the point selected in the drop-down list. These changes include Feature Point Parameter, U and V values, point name, etc.
[Summary]: Displays the coordinates and information about the currently active point or feature.
•Material: Reverses the vector of the Feature and all Feature Points on the selected feature. This also changes the Material direction of a Pin or hole.
•Axis: Switches the direction of a cylindrical feature and the Feature Points created on the cylinder's axis (Center).
Best Practices - Project Feature Point: Update or Edit a Feature Point.
1.Select Feature Point on the 3DCS Model Creation Toolbar or navigate to it in the 3DCS drop-down list (Features -> Feature Point).
2.Select [Point] and select the Feature Point/Coordinate Point to be projected.
3.Select [Convert to Coordinate Point] to convert the Feature Point into a Coordin5+ate Point.
4.Select [Feature] and select the new surface on which the point will be projected.
5.Make sure the Move Original Point option is selected to move the original point onto the new surface.
6.Select [Project on Feature] to project the point onto the new surface.
Switch Direction Procedure:
1.Select [Feature] and then select a feature in the Graphics window or Navigation tree.
2.Select either [Material] or [Axis].
a.If changing a Pin to a Hole, select the [Material] option.
b.If changing a planar feature direction, select the [Material] option.
c.If changing the direction of an axis of a pin or hole, select the [Axis] option.
Feature Locator Point: When a feature is selected in an MTM or GD&T, the function will be using the Feature Locator Point associated with that feature. The Feature Locator point is not a user-created point and does not appear in the Points dialog. By default the point is at the center of the feature (calculated from the average of Mesh Nodes), but its location can be modified with the X and Y input fields when the feature is active in the Feature Point dialog. The Feature Locator Point location is represented by a red x when an existing feature is highlighted (see below.)
