Creating a Beam Using Point and Limit

	This task shows how to create a beam using point and limit.
	1.	With your 3-D session open, click the `Beam` button . The `Beam` dialog box displays with the `Geometry` tab selected.
	2.	Select from the `Category` drop down list. (This task uses `Beam` as an example.) You can select `More` to display the `Class Browser`, and select from what is available in the catalog. The name of the beam is assigned automatically, using the object naming rules. If you want to assign your own name to the beam, uncheck the `Automatic` box and enter a name.
	3.	Select `Point and Limit` from the `Type` drop down list.
	4.	In the `Point` field, select points where you want to create beams. You can do any of the following: Select the extremities of existing beams. (The extremity nearest your selection point is the one selected.) Select a point in your 3-D session, or a point on the plane system grid. (Make sure the `Selectable` `Points` checkbox is selected on the `Plane System Grid` dialog box.) Right-click and select from the list of GSD stacking commands. You see the beams display as you make your selections (limited by the deck).
	5.	When selecting points, you can click alongside the `Point` field, and the `Point` dialog box displays. The `Point` dialog box lists the points you selected. You can use the dialog box to replace a point with another point. Select the point you want to replace from the list, and click the `Replace` button. Select a point in the 3-D session, and this point displays in the `Point` dialog box list in place of the original point. (The corresponding beam moves to the location of the point on the grid.)
	6.	You can also remove points from the list in the `Point` dialog box. Select the points you want to remove from the list, and click the `Remove` button. The selected points are removed from the list, and the corresponding beams are deleted in the 3-D session, and in the specifications tree. Click `Close` when you have made all the necessary changes. NOTE: If the points you removed from the list were selected on the plane system grid, or were created using the list of GSD stacking commands, the points are removed from the 3-D session. If you used the `Generative Shape Design` workbench to create points, these points are not removed from the 3-D session.
	7.	In the `Limit` field, select a plane in your 3-D session to limit your beams, or you can right-click and select from the list of GSD stacking commands.
	8.	In the `Direction` field, select a line or plane in your 3-D session to select the direction for the beam, or you can right-click and select from the list of GSD stacking commands. NOTE: The `Direction` field displays `xy plane` as the default selection. If you clear the selection and right click, only the GSD stacking commands beginning from `Create Line` are available.
	9.	You can click the `Reverse` `Direction` button to change the orientation of the beams. Click `OK` on the `Beam` dialog box when you are done.
	10.	You can change the values of a beam by double clicking on the beam in your 3-D session. The `Beam` dialog box displays. Change the values as required. Some fields are not available, and cannot be changed (such as `Category`).
