Contour Manager (NC) > By Criteria Selection

The Criteria selection dialog displayed in the NC environment (the Sets - Create and Edit dialog) is very similar to the dialog displayed in the CAD environment. However, in NC, some parameters are not displayed, while additional parameters may appear in the dialog, depending on the type of geometry being selected.

Criteria dialog for selecting Part/Check/Overlap surfaces:

Criteria dialog for selecting 2D Bounding contours:

Criteria dialog for selecting Spun Silhouette contours:

Criteria dialog for selecting Contours:

Criteria dialog for selecting Contours for the Chamfer Open Contour and Chamfer Closed Contour procedures:

The By Criteria creation method is very similar to selecting multiple geometric entities manually, the only difference is the way the input is gathered. Using the By Criteria method, the input is automatically selected according to the criteria definition.

The following additional parameters are displayed in the NC "By Criteria" dialog (these are very similar to the same parameters in the Multi Contours Selection):

Boundaries (of faces)

This parameter appears in Contour selection By Criteria. Create contours from faces that meet the criteria, based on one of the following dropdown list of options (this is very similar to the same parameters in the Multi Contours Selection):

None

Do not create contours from faces.
This is the default option.

Outer Only

Create contours from the outer boundaries of groups of selected faces.

This option also appears when creating Automatic Boundaries. See Automatic Boundaries for additional information.

Inner Only

Create contours from the inner boundaries of groups of selected faces.

This option also appears when creating Automatic Boundaries. See Automatic Boundaries for additional information.

Outer and Inner

Create contours from the outer and inner boundaries of groups of selected faces.

This option also appears when creating Automatic Boundaries. See Automatic Boundaries for additional information.

From Vertical Walls

Create contours from the boundaries of the vertical walls of groups of selected faces. The system automatically applies Z-Top and Z-Bottom attributes to each contour, which can be used or refined. The Z Values Source parameter enables you to use the same Z-Top and Z-Bottom parameters for all contours or to use varying heights for each contour.

This is the default option for all 2.5 Axis procedures. For additional information on the automated machining of vertical walls using these Pocket and Profile procedures, see the Z Values Source parameter explanation.

2D Bounding

See here for additional information.

 

Spun Silhouette

Chamfer Detect

When the Chamfer Detect option is selected, additional parameters are displayed; see Chamfer Detect Parameters for details.

A group of faces may have one or more faces.

Faces Grouping Max. Gap

Contours Creation Max. Gap

Half / Full

  • The above parameters are saved together with the criteria conditions definition so they are applied each time the contours created by a criteria definition are recalculated.

  • See Creating Sets By Criteria for a description of the remaining parameters of this dialog.
