Part 1) Open the Example File

  1. in the File menu, click Open.

    The Open dialog appears.

  2. Select the folder in which you saved the example file.

  3. Select Pig Art Emboss.3dm, and click Open.

 

The file is opened and the geometry is displayed in the graphics area.



Part 2) Regular Emboss 1 - Body

Insert the Feature and Define Stock

 

  1. In the BobART Manager tab, right-click Emboss Model, and click Emboss Regular.

    The Stock Parameters dialog box opens.

  2. In the Model Size group, set the X value to 229.000, and set the Y value to 305.000.

  3. Click OK.

 

The Emboss dialog box opens.

 

Edit the Feature Parameters

 

  1. Click Color, select pink, and click OK.

  2. Click the Cross Section arrow, and click Convex Ellipse.

    In the Major Axis box, type 102.000.

    In the Minor Axis box, type 13.000.

  3. Click the Application Type arrow, and click Add.

 

The Add application type adds the emboss to the stock surface.

 

Click OK.

 

Select Feature Geometry

 

  1. Under Regular Emboss 1 - Add, right-click Geometry, and click Re/Select.

  2. In the graphics area, select the geometry that represents the body of the pig as shown next.

 

 

To confirm the selection, click OK.



 

Generate the Emboss

 

  1. Right-click Emboss Model, and click Regenerate.

 

The body is now embossed and appears as shown next.

 

Part 3) Regular Emboss 2 - Nose

Insert and Edit the Feature

 

  1. Right-click Emboss Model, and click Emboss Regular.

    The Emboss dialog box opens.

  2. Click Color, select pink, and click OK.

  3. Under Emboss, click the Cross Section arrow, and click Convex Ellipse.

    In the Major Axis box, type 19.000.

    In the Minor Axis box, type 13.000.

  4. Under Application Type, click the arrow, and click Merge High.

 

Click OK.

 

Note: Most, but not all of the nose geometry overlaps the body geometry. Merge High is used to create the nose with one consistent height. If the Add application type is used, then the area of the nose that does not overlap the body geometry would not be the same height as the rest of the nose (this is shown at the end of Part 3). Merge High leaves only the highest area of intersection between two embossed features.

 

Select Feature Geometry

 

  1. To hide the embossed model, right-click Emboss Model, and click Blank/Unblank.

  2. Under Regular Emboss 2 - Merge High, right-click Geometry, and click Re/Select.

  3. In the graphics area, select the geometry that represents the nose of the pig as shown next.

 

 

To confirm the selection, click OK.


 

Tip: To hide or show the stock, right-click Emboss Model and click Blank/Unblank. This is helpful when you have already created an Emboss feature but need to select geometry that is hidden within (or behind) the stock model.

 

Generate the Emboss

 

  1. To show the embossed model, right-click Emboss Model, and click Blank/Unblank.

    (You can also click in the graphics area and press E.)

  2. Right-click Emboss Model, and click Regenerate.

 

The nose is now embossed and appears as shown next.

 

 

For comparison, an image of the same feature is shown using the Add application type as mentioned previously.

 

Part 4) Regular Emboss 3 - Face

Insert and Edit the Feature

 

  1. Right-click Emboss Model, and click Emboss Regular.

  2. Click Color, select pink, and click OK.

  3. Click the Cross Section arrow, and click Convex Ellipse.

    In the Major Axis box, type 26.000.

    In the Minor Axis box, type 6.000.

  4. Click the Application Type arrow, and click Merge High.

 

Click OK.

 

Select Feature Geometry

 

  1. To hide the embossed model, right-click Emboss Model, and click Blank/Unblank.

  2. Under Regular Emboss 3 - Merge High, right-click Geometry, and click Re/Select.

  3. In the graphics area, select the geometry that represents the face of the pig as shown next.

 

 

To confirm the selection, click OK.


 

Generate the Emboss

 

  1. To show the embossed model, right-click Emboss Model, and click Blank/Unblank.

  2. Right-click Emboss Model, and click Regenerate.

    Notice that the face emboss does not show. This is because the height of the body is greater than the height of the face, and the Merge High application type is used.

  3. To edit the feature, right-click Regular Emboss 3 - Merge High, and click Edit.

    In the Base Height box, type 13.000.

    This adds a 13.000 mm foundation to the base of the emboss feature which can now extend up through the body.

    Click OK.

  4. Right-click Emboss Model, and click Regenerate. The result should look as follows.



  5. Notice that the face now covers the nose. This is not the desired result. To resolve this issue you add a base height to the nose emboss operation.

  6. Right-click Regular Emboss 2 - Merge High (nose), and click Edit.

    In the Base Height box, type 10.000. This adds a 13.000 mm foundation to the nose feature.

    Click OK.

  7. Right-click Emboss Model, and click Regenerate. The model should appear as follows.

 

Part 5) Regular Emboss 4 - Nostrils

Insert and Edit the Feature

 

  1. Right-click Emboss Model, and click Emboss Regular.

  2. Click Color, select black, and click OK.

  3. Under Cross Section, select Convex ARC.

 

Confirm the Radius is set to 6.000.

 

In the Start Angle box, type 60.00.

 

Confirm the End Angle is set to 90.00.

 

Tip: Notice that the Start Angle is changed to 60 degrees, instead of 0 degrees. The embossed model now starts 60 degrees into the defined Cross Section. The result is that the edge of the model has a more gradual slope in relation to the stock. The following image shows two identical Regular Emboss features with the first starting at 0 degrees, and the second starting at 60 degrees.



It is important to explore the various settings of the Emboss features. Changing one setting can create a substantial difference in the result. By experimenting with the different settings, you can find multiple ways to accomplish the same task, with variations in the result. Knowing these variations helps you greatly when creating embossed models.

 

  1. Click the Application Type arrow, and click Subtract.

 

The Subtract application type removes material. This makes the nostrils recessed into the nose.

 

Click OK.

 

Select Feature Geometry

 

  1. To hide the embossed model, right-click Emboss Model, and click Blank/Unblank.

  2. Under Regular Emboss 4 - Subtract, right-click Geometry, and click Re/Select.
