Opening Types

The Opening type list contains the preparation types that the user can manufacture. Available types include Cut, Tabbed, Bridged, Marked, Drilled and None.

To change a specific cutout's type from the default, select it and then select the desired opening type from the Opening type list.

The Cut type is provided to specify that the selected opening is not to be prepared. Therefore, when Cut is selected for a given opening, no manufacturing feature is created and the opening is no longer shown in the Opening Preparation dialog box. If it is determined that the selected opening requires preparation at a later date, the Add button can be used to retrieve it (as shown in Step 4 above).

For tabbed and bridged openings, additional parameters are provided in the dialog box.

For Tabbed openings, additional parameters are provided to specify:

  • Tab Width (you can see the width change in the 3D viewer as you alter the values in the dialog box)

  • Lead in Length/Lead Out Length: If the length of lead is set to zero, then the burning machine begins its movement from specific point that lies on the contour.

  • Lead Side (you can specify right or left)

  • the Min. number of tab points

  • the Max. distance between tab points.

For Bridged openings, a Width parameter is provided to input the width of the bridge. The Direction parameter specifies the direction in which the bridge should be made.
