10. Click OK to generate the grill.
The grill is the most flexible feature for plastic parts. A wide selection of sub-
features allows you to pick and choose the elements you want to place.
Embossing or Engraving
The rules for creating an embossed or engraved feature, such as the product logo,
are the same as if you were going to extrude a solid feature. You can use a closed
sketch or text to define the feature's geometry.
1. Verify that the 2013 Essentials project file is active, and then open
c09-09.ipt from the Parts\Chapter​9 folder.
2. Position the model so you can see the text in the sketch above the
grill feature.
3. Start the Emboss tool from the Create panel of the 3D Model tab.
