  5. In the Radius box, type 0.0625.

  6. Confirm that the Start Angle is set to 0.00 and the End Angle is set to 90.00.

  7. Set the Application Type to Add.

  8. To close the dialog box and add the feature, click OK.

Part 3) Select Geometry for the Feature

Part 4) Regenerate the Model

After making changes to any Emboss feature, you must regenerate to add the changes to the model.

When the view of the model is rotated, you can see that the Emboss Swept feature added the 0.0625 arc sweep to the model. The entire sweep is added on top of the previous features. In the next part, you edit the feature so that less of the sweep is added to the model.

Part 5) Edit the Feature

  1. In the BobART tree, right-click Top Emboss Swept 6 - Add, and click Edit.

  2. In the Emboss group, click the Application Type arrow, and click Merge High.

  3. Click OK to close the dialog box.

    The Emboss Swept feature now only keeps the highest parts of the overlapping features.

  4. To add the change, right-click Emboss Model, and click Regenerate.

  5. Notice that the Emboss Swept feature is no longer visible in the model.

    This is because the 0.0625 sweep is less than the 0.2500 Emboss Regular feature.

    The Merge High Application Type only keeps the highest portion of the model.

  6. Edit the feature (as shown in Step 1).

     In the Base Height box, type 0.200.

    This is done to raise the level (in Z) of the swept feature while retaining the specified cross section.

    Click OK.

  7. To add the changes, right-click Emboss Model, and click Regenerate.

 

The swept feature is now at the desired height.

The first Emboss Swept feature is now complete. The feature adds a subtle improvement to the appearance of the model. This adds more detail to the model that can be seen when the model is machined.

Part 6) Add the Emboss Swept Feature 2

The next swept feature is used to add detail to the model in a similar way to the previous swept feature. The same geometry selections from the How to Create an Emboss Regular tutorial are used for the mug body, bottom, handle, and the steam. The result is that an outline of each of these sections is added to the mug. Three of these geometry items receive the exact same emboss, and for this reason, multiple geometry selections are combined into a single feature.

 

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

  2. In the Emboss dialog box, click in the Name box.

    Type Mug at the beginning of the description so it displays Mug Emboss Swept 7.

  3. Click Color.

     In the Color dialog box under Basic Colors, click the black color, and click OK.

  4. In the Emboss group, under Cross Section, confirm that Convex Arc is selected.

  5. In the Radius box, type 0.125.

    Confirm that the Start Angle is set to 0.00 and the End Angle is set to 90.00.

  6. In the Emboss group, click the Application Type arrow, and click Merge High.

  7. To close the dialog box and add the feature to the tree, click OK.

Part 7) Select Geometry for the Feature

  1. To view the geometry that is hidden by the model, hide the model.

  2. Under Mug Emboss Swept 7 Merge High, right-click Geometry, and click Re/Select.

  3. Chain select the following items.

    (To chain select multiple connected entities, you press and hold Shift, and then click an entity.)

    Press Shift, and click the lowest line.

Even though the geometry for the Emboss Swept feature defines the center of the emboss/feature, only the outer portion of the cross-section is what appears on this model. This is a result of using the Merge High Application Type. The inside portion of the sweep is lower than the rest of the embossed model, and only the highest part of the model is kept.

Part 9) Add the Emboss Swept Feature 3

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

  2. In the Emboss dialog box, click in the Name box, and type Steam at the beginning of the description.

    Set the Start Angle to 0.00 and the End Angle to 90.00.
