Pig Art Emboss Tutorial

Introduction

This tutorial is designed to help you become familiar with the BobART Emboss features. The Emboss Regular, Emboss Swept, and Emboss 2-Rail Sweep features are used to create a piggy-bank BobART model. Follow this tutorial along with the other Emboss tutorials to learn more about the BobART Emboss features.

Example File

The part file for this tutorial is available for download at: http://www.bobcad.com/helpfiles. If you are connected to the Internet, you can click the link provided to download and save the Pig Art Emboss Example.sldprt zip file. After downloading the zip file, extract the files on your system in a place that is easy to remember. You can then open the file (.sldprt) to use with this tutorial.

Part 1) Open the Example File

  1. in the File menu, click Open.

    The Open dialog box is displayed.

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

  3. Select Pig Art Emboss.sldprt, 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 9.00, and set the Y value to 12.00.

Note: The resolution updates automatically as the size is updated. The Resolution will improve the quality of the model, but also increase the size of the file, and the amount of time it takes to regenerate the surface.

The image on the left shows stock with a resolution of 25, while the image on the right shows stock with a resolution of 150.



Normally, since ultra fine details will not be visible on the final machined part, a higher resolution stock is not really needed. However, if it is wanted, wait until the model is complete and adjust the resolution at the end. This will keep regeneration times low during the creation of the model.

 

  1. Select the Remove Non-Emboss Area check box.

  2. Click OK.

 

The Emboss dialog box opens.

 

Edit the Feature Parameters

 

  1. In the Emboss Attributes group, change the Name to Body.

  2. Click Color.

    The Color dialog appears.

    Select pink.



  3. Click OK.

    The Color dialog disappears.

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

    In the Major Axis box, type 4.00.

    In the Minor Axis box, type 0.50.

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

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

  6. Click OK.

 

Select Feature Geometry

 

  1. Under Body - 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) in the Property Manager.


 

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. Change the Name to Nose.

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



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

    In the Major Axis box, type 0.750.

    In the Minor Axis box, type 0.500.

  5. 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. Under Nose - Merge High, right-click Geometry, and click Re/Select.

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

 

 

Click (OK).

 

Tip: To hide or show the stock, you can right-click Emboss Model and select Blank/Unblank.

 

Generate the Emboss

 

  1. 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 Merge High on the left, and Add on the right, as mentioned previously.

 

Part 4) Regular Emboss 3 - Face

Insert and Edit the Feature

 

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

  2. Change the Name to Face.

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



  4. Click the Cross Section arrow, and select Convex Ellipse.

    In the Major Axis box, type 1.000.

    In the Minor Axis box, type 0.250.

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

 

Click OK.

 

Select Feature Geometry

 

  1. Under Face - Merge High, right-click Geometry, and click Re/Select.

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

 

 

Click OK.

 

Generate the Emboss

 

  1. 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.

  2. To edit the feature, right-click Face - Merge High, and click Edit.

    In the Base Height box, type 0.500.

    This adds a 0.500 inch wall to the base of the emboss feature which can now extend up through the body.

    Click OK.

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



  4. 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.

  5. Right-click Nose - Merge High, and click Edit.

    In the Base Height box, type 0.375. This adds a 0.375 inch base to the nose feature.

    Click OK.

  6. 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. Change the Name to Nostrils.

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



  4. Under Cross Section, select Convex ARC.

 

Confirm the Radius is set to 0.250.

 

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. Under Nostrils - Subtract, right-click Geometry, and click Re/Select.

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

 

 

Click OK.
