How to Use Revolved Surface

Example 1 (Enter the Revolve Axis)

This example will demonstrate how to use the Revolve Surface function.

NOTE:      In the images below, the Show Axis X-Y toggle has been disabled in the Axis X-Y group of the Settings Part > Display dialog. The Gnomon has been used to show the axes of rotation.

 

1      In the File menu, click Open.

2      In the Open dialog box, navigate to C:\BobCAD-CAM Data\BobCAD-CAM V**\Examples.

NOTE:      This is the default install location. If you performed a custom install, navigate to the location in which you installed the software.

 

3      Select revolved surface example.bbcd, and click Open.

The file opens.

 Leave the file in the ISO 2 view.

4      Open SurfaceRevolve.png Revolve by selecting the function from Surfaces menu.

The Revolve Surface parameters display in the Data Entry tab of the Data-CAM Tree Manager.

5      Deselect the Preview check box.

NOTE:      This step is not necessary to the creation of a Revolve and is used in this example only to allow us to see the result of the chain selection easier.


6      In the graphics area, hover over the entity shown below, and press and hold Shift, before clicking the entity to chain-select the entire chain.

NOTE:      Notice that the direction arrow is now displayed on the geometry. When you chain select an entity for functions that have a direction, the nearest snap point of the entity that you select is defined as the end of the chain. Alternatively, you can click an entity to define the start of the chain, and then hold Shift and click the end of another entity to define the end of the chain. The steps in this example eliminate the extra selection. When you are selecting a closed chain to revolve, the start and end location of the chain are not important.

7      Select the Preview check box.

The Preview displays.

8      In the Rotation Angle box, enter a value of 90.00 and press Tab.

The Preview Updates

9      Select the With Caps check box.

The Preview updates to show the Revolve Surface being created as solid instead of a single revolved surface.

10  To create the geometry as shown in the CAD preview, in the Data Entry tab, click OK. The profile is revolved 90 degrees around the X-axis and a SurfaceRevolve.png Revolve feature is created in theCADTreeIcon.bmp CAD Tree.

11  To end the function, click Cancel.

 

 

This concludes Example 1. Leave the file open and continue to Example 2 to learn more about Revolve Surface.

Example 2 (Pick the Revolve Axis)

1      After completing Example 1, press Ctrl+Z to undo the last revolve. Or, in the Edit menu, click Undo.

2      Open Rotate.png Rotate by selecting the function from Utilities menu.

The Rotate parameters display in the Data Entry tab of the Data-CAM Tree Manager.

3      Hover over the an entity in the chain, then hold Shift and click that entity to chain select the entire chain.

4      Right-click and select OKCheckmarkIconWhite.png OK to confirm the geometry to be rotated.

5      For the Angle Around Axis group, enter:

 

For the Origin group, enter:

 

The Preview updates for each entry. With the values entered, the preview should match the one seen in the image below.

6      Click OK to finalize the rotation.

The Preview updates to show the results should the current values be applied again.

7      Open SurfaceRevolve.png Revolve by selecting the function from Surfaces menu.

The Revolve Surface parameters display in the Data Entry tab of the Data-CAM Tree Manager.

8      Click the entity shown in the image below to set the start point and direction of the Revolve Curve.

The Start arrow appears.

9      Hold Shift and click the entity shown in the image below to set the end point of the Revolve Curve.

The Preview appears.

Notice it is not the result obtained from Example 1. Since we have rotated the wireframe, it's intended rotation axis is no longer parallel to the X Axis.

10  In the Rotation Axis group, click Pick Axis. This will allow us to select the rotation axis for the function from geometry in the graphics area.

The preview disappears.

11  Click in the Rotation Axis list to give it focus.

The Rotation Axis list highlights to allow us to select the Rotation Axis.

12  Click the entity shown in the image below.

Once selected, the Preview displays.

13  Click OK to finalize the Revolve.

The surface is created in the graphics area  and a SurfaceRevolve.png Revolve feature is created in theCADTreeIcon.bmp CAD Tree.

NOTE:      Notice, even though we have With Caps selected, we have not created a solid. To create a solid that does not revolve a full 360 °, a closed chain needs to be selected as the Revolve Curve.

 

 

14  To end the function, click Cancel.

 

 

 

 

This concludes the examples.
