2-Rail Sweep 1 - Add (Each
feature is numbered and includes the Transition Type)This tutorial explains the basic setup and general process to create an Emboss 2-Rail Sweep using BobART.
When creating a 2-rail sweep you must first define the stock. This stock defines the area in which you can create an emboss. The next step is to create 2 rails inside the stock. These rails can be open or closed shapes such as two parallel lines, or two offset rectangles; and they can be 3-dimensional. The two rails must share the same chain direction. After creating two rails at least one cross-section geometry is needed. The cross section (width) must be drawn horizontally along/parallel to the X-axis.
IMPORTANT: You cannot use a cross section that is drawn vertically in the Y-axis. So, the start and end point of a cross section cannot share the same X-value. The width of the cross section is taken from the change in X-values and the height is taken from the change in Y-values.
When using more than one cross section the chain direction should also be shared among all cross sections. The start point of the cross section is connected to rail 1 and the end of the cross section is connected to rail 2. Once all of these items are created, the cross-section geometry is swept along the two rails to create an Emboss 2-Rail Sweep from the stock surface.
1 Open BobCAD-CAM and click File, New.
2 In the BobART tab, right-click Emboss Model, and click Emboss 2-Rail Sweep.
Because no stock is defined the Stock Parameters dialog box appears.
Set the desired stock parameters and click OK.
The 2-Rail Sweep dialog box appears. Click OK. The stock is displayed in the Workspace.
The following items are added to the BobART tree below Emboss Model:
2-Rail Sweep 1 - Add (Each
feature is numbered and includes the Transition Type)
Rail 1-Geometry
(Stores the geometry for the first rail)
Rail 2-Geometry
(Stores the geometry for the second rail)
Cross-Section Geometry-1
(Stores the geometry for the first cross section)
3 Draw the first rail and the second rail inside the boundary of the defined stock.
Draw one or more cross sections in the Workspace either inside or outside the boundary of the defined stock.
4 Right-click
Rail 1-Geometry, and click Re/Select. In the Workspace, select
the appropriate geometry, and click 
OK.
Right-click Rail 2-Geometry, and
click Re/Select. In the Workspace,
select the appropriate geometry, and click OK.
Make sure the chain direction of each rail is the same. To view the chain-direction
arrow, click the Rail Geometry
item in the BobART tree.
Right-click Cross-Section Geometry-1,
and click Re/Select. In the Workspace,
select the appropriate geometry, and click OK.
Make sure the desired chain direction is achieved. The start point of the cross section is connected to rail 1 and the end of the cross section is connected to rail 2.
5 Right-click 2-Rail Sweep 1 - Add, and click Edit.
The 2-Rail Sweep dialog box appears.
Select the desired parameters that are explained
in the Emboss 2-Rail Sweep help topic. Click OK.
6 Right-click Emboss Model, and click Regenerate. The Emboss 2-Rail Sweep is finished.
NOTE: Remember that every time a
2-Rail Sweep parameter is changed, you right-click 
Emboss Model, and then click Regenerate to see the changes reflected
in the model.
