The tool list only includes tools that are valid for the step.| | To show tools for the current step and the active head on the machine tool, set the INCLUDE_ALL_TOOLS_IN_LIST option to YES. |
Alternatively, right-click in the graphics window and select Tools.
5. To preview the cutting tool and its orientation in the graphics window, click 
to the right of the tool list box. The button becomes available once a tool is selected.

To exit the tool preview, right-click the graphics window and select Cancel tool preview from the shortcut menu.
6. To change the coordinate system that defines the orientation of the step, click the collector adjacent to 
and select a coordinate system. If the operation coordinate system differs from the step coordinate system, right-click the collector for the following commands:
and select a coordinate system. If the operation coordinate system differs from the step coordinate system, right-click the collector for the following commands:◦ Default—Replaces the selected coordinate system with the default reference. The default is the orientation that is copied from the previous step or from the operation.
◦ Information—Displays the information of the selected coordinate system.
| | After you specify a coordinate system for an NC sequence, it remains in effect until you change it. |
Alternatively, right-click the graphics window and select Orientation from the shortcut menu.
7. Select any one of the following machining references using the References tab. The machining references collector in this tab enables you to collect only a single type of reference based on your first selection. For example, if you select a Cosmetic Groove feature, all the references that you can select following the first reference are only Cosmetic Groove features. The same rule applies to Datum Curves and Reference Model Edges.
◦ Cosmetic Groove Feature—Select a reference Groove feature. You can select multiple Groove features by holding down the CTRL key.
◦ Datum Curve—Select a curve. You can select multiple curves by holding down the CTRL key. You can also click Details below the machining references collector to open the Chain dialog box that enables you to gather segments of curves or rule-based segments.
◦ Reference Model Edges—Select the edges for the tool to follow. You can select only one open or closed loop of edges. You can also click Details below the machining references collector to open the Chain dialog box that enables you to select chain of edges.
◦ Normal Surface—This option is available only for 4- and 5- axis engraving steps. It is applicable only when the first collected reference is an edge of the reference model or a datum curve.
Select a surface that the tool axis will be normal to. If the machining reference is a reference model edge, you can select surfaces of the same reference model adjacent to the selected edge as the Normal Surface. If the machining reference is a datum curve, you can select any type of surface from any model within the same assembly as the Normal Surface.
Alternatively, right-click the graphics window and select Machining References or Normal Surface from the shortcut menu.
8. On the Parameters tab, specify the required manufacturing parameters.
You can also click 
to copy parameters from an earlier step or click 
to edit parameters specific to engraving. By default, the required parameters are defined by relations that you can modify from the Relations dialog box.

9. On the Clearance tab, optionally specify the following:
◦ Retract—Specify the Type, Reference, Orientation, and Value for the retract definition
◦ Start and End Points—Specify the Start point and End Point for the step tool path.
Alternatively, right-click the graphics window and select Retract. You can also select the Start Point and End Point of the cutting tool from the shortcut menu.
10. On the 4-axis Plane tab, select any flat surface except a surface parallel to the retract plane. You can also select a plane to which the tool axis will be parallel. This tab is available only for 4-Axis Engraving sequences.
11. On the Options tab, select a part or assembly to use as a cutting tool adapter.
12. On the Tool Motions tab, select the options to create, modify, and delete tool motions and CL commands for defining cut motions. For details on all the tool motions, see the topics under Related Links.
Alternatively, right-click the graphics window and select Tool Motion Options.
| | With the Return to Step Options option on the shortcut menu in the graphics window you can switch from editing tool motions and editing step references. This option is available only when all references for tool path computation are successfully defined. |

15. On the Properties tab, optionally specify the name or comments for the step.
◦ Name—Displays the name of the step. You can type another name.
◦ Comments—Type the comments associated with the step in the text box or use the following options:
▪ 
—Read in an existing text file containing step comments and replace any current step comments.
—Read in an existing text file containing step comments and replace any current step comments.▪
