When you import a STEP file to Creo Elements/Direct Modeling from another CAD system, the information about the features, like drill features or hole patterns, is lost. Creo Elements/Direct Part Library allows you to identify the missing features and add them to the Structure Browser.
To identify a drill feature,
1. In Creo Elements/Direct Modeling, click Part Library and then, in the Drill group, click the arrow next to Create.
2. Click Identify. The Identify Drill Features dialog box opens.
3. Click Part and select the desired part either from the Structure Browser or in the viewport. Creo Elements/Direct Part Library defines all faces that contain drill features in the Faces box.
4. To exclude a drill feature from the feature identification process you can do one of the following in the Exclude section:
a. Click Axis and select a cylindrical face to exclude the drill features along the axis of the selected face.
b. Click Faces and select the face to be excluded.
5. Click Machining Feat in the Exclude section to exclude the machining feature from the feature identification process.
6. Click Analyze. Creo Elements/Direct Part Library searches for all the available drill features and displays the results in the Structure Browser.
• If you click the Create check box in the HolePattern section, the hole features that have identical geometry, identical dimensions, the same direction, and have a co-planar start points are created as one hole pattern in the Structure Browser. If the start points of otherwise-identical holes lie on different planes, different hole patterns are created in the Structure Browser.
• If you do not click the Create check box in the HolePattern section, only drill features, and not hole patterns, are created in the Structure Browser.
