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

If you are connected to the Internet, the part file for this example can be downloaded automatically by clicking the following link: Pig Art EmbossExample.bbcd

Once you download and saved the zip file, extract the files on your system in an easy place to remember.You can then open the file to use with this tutorial.All files for the tutorials in this help system available for download can be found by clicking on the following link: http://www.bobcad.com/helpfiles.

Part 1) Open the Example File

  1. in the File menu, click Open.

    The Open dialog is displayed.

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

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

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

Part 2) Define the Canvas

  1. In the BobART Manager tab, right-click Emboss Model, and click Create/Modify Canvas.

    The Canvas Definition dialog opens.

  2. By default the UCS is set to Top(X/Y) which is the desired UCS for this example.

  3. In the Model Size group, set the Xvalue to 9.00, and set theY 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. At this point, as an option, you can also select the Remove Non-Emboss Area check box.

    This will remove any area of the canvas that is not being utilized by a BobArt feature.

  2. Click OK.

    The canvas appears in the graphics area.

  3. Click Cancel.

    The Canvas Definition dialog disappears.

Part 3) Regular Emboss 1 - Body

Create the feature and set Attributes

 

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

    The Emboss Regular dialog opens.

  2. For the Name, add Body to the front of the text so our feature name reads Body Regular Emboss 1.

  3. Click the drop down next to Color,and select More Colors....

    The Select Color dialog appears.

  4. In the vertical color spectrum bar, click on the pink area, or you can use R 250, G 125, B 200 values, then click OK.

    The Select Color dialog disappears and the color is set to pink.

    By default the Application Type is set to Add and the Selected Geometry list has focus.

 

Select Geometry


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



    The geometry is added to the Selected Geometry list.

 

Define the Cross-Section


  1. Click the Cross-Section option to access the drop down list, and select Convex Ellipse.

  2. Set the X Axis Radius value to 4.00.

  3. Set the Y Axis Radius value to 0.50.

  4. Click OK.

    The body is now embossed and appears as shown next.



  5. Click Cancel to exit the dialog.

Part 4) Regular Emboss 2 - Nose

Create the feature and set Attributes

 

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

    The Emboss Regular dialog opens.

  2. For the Name, add Nose to the front of the text so our feature name reads Nose Regular Emboss 2.

  3. Click the drop down next to Color, and select More Colors....

    The Select Color dialog appears.

  4. In the vertical color spectrum bar, click on the darker pink area, or you can use R 255, G 0, B 255 values, then click OK.

    The Select Color dialog disappears and the color is set to pink.

  5. Set the Application Type to Merge High.

 

Select Geometry


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



    The geometry is added to the Selected Geometry list.

 

Define the Cross-Section


  1. With Convex Ellipse still selected as the Cross-Section, set the X Axis Radius value to0.750.

    Leave the Y Axis Radius value at0.500.

  2. Click OK to update the canvas.

    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.



  3. Click Cancel to exit the dialog.

 

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.

 

Tip: To hide or show the stock, you can click in the graphics areaand press E, or 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.

Part 5) Regular Emboss 3 - Face

Create the feature and set Attributes

 

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

    The Emboss Regular dialog opens.

  3. Click the drop down next to Color,and select More Colors....

    The Select Color dialog appears.

  4. In the vertical color spectrum bar, click on a slightly different pink area, or you can use R 255, G 128, B 192 values, then click OK.

    The Select Color dialog disappears and the color is set to pink.

  5. The Application Type should still be set to Merge High which is what we want for this part.

 

Select Geometry


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



    The geometry is added to the Selected Geometry list.

 

Define the Cross-Section


  1. Click the Cross Section still set to Convex Ellipse, update the X Axis Radius value to 1.000.

  2. Set the Y Axis Radius to0.250.

  3. Click OK.

    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.

     

Update the Base Height

 

  1. In the Base Height field, enter0.500.

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

  2. Click OK.



    The result should look as follows.

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

  3. Click Cancel.

 

Update the Nose Regular Emboss 2 - Merge High feature


  1. Right-click Nose Regular Emboss 2 - Merge High, and click Edit.

    The Emboss Regular dialog opens.

  2. In the Base Height field, type 0.375.

    This adds a 0.37500 inch foundation to the nose feature.

  3. Click OK.



    The model should appear as follows.

  4. Click Cancel.

Part 6) Regular Emboss 4 - Nostrils

Create the feature and set Attributes

 

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

  3. Click the drop down next to Color, and select Black.

  4. Set the Application Type to Subtract.

 

Select Geometry


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



    The geometry is added to the Selected Geometry list.

 

Define the Cross-Section


  1. Set the Cross-Section to Convex ARC.

  2. Set the Radius value to 0.250.

  3. In the Start Anglefield, enter 60.00.

  4. Confirm the End Angle is set to 90.00.

 

Update the Base Height


  1. Set the Base Height to 0.00.

  2. Click OK.

 

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.
