If you suspect that a part may be corrupt, you can check it for problems using the Check Part dialog box. If the part checker detects problems with the part, it highlights the edges of the problem area.
Most Modify3D commands have an automatic Chk & Fix check box option that checks the part being modified and applies command-specific fixes. However, to speed up modifications, you can clear the Chk & Fix check box before starting the modification. Later when you want to check the part, you can do so explicitly using the Check Part command. This part check does not fix the part, except for some minor faults in the internal representation.
Be sure to check your part periodically if the Chk & Fix check box is cleared. The part checker uses the configuration in the System Settings dialog box to select the features that cause warnings to be reported when they are detected in a part. You can temporarily change these settings in the Check Part dialog box during a part check operation.
By default, the part checker reports warnings in the output box when the following invalid parts are identified:
• Edges shorter than the minimum edge setting.
• Surfaces with more control points than the maximum control points setting.
• Void shells
• Non-manifold parts
• Knife-edges
If the part checker reports "non-manifold" parts or other warnings, you may continue with your design, but be aware that parts that join one another along an infinitely thin edge, or at an infinitely small point, are not manufacturable.
When you activate the part checker, it checks the features in the specified parts once and, when found to be correct, those features are not checked again until these features are modified. This incremental checking helps to enhance both the performance of the part checker and Creo Elements/Direct Modeling.
The Minimal option of the part checker is usually sufficient to find any problems with a part. In the following cases, however, a complete check (click the Maximal check box) is recommended:
• When you finish designing a part before sending it off for further processing.
• When you visually examine a part and notice a fault or ambiguity.
• If you have made several operations with cleared Chk & Fix check box.
The part check process can take considerable time for complex parts, especially when the Maximal option is used. In this case, it may be desirable to perform the part check on a second computer using the Remote Update Server functionality.
To check a part for problems,
1. Click Analysis and then, in the Verify group, click Check Part. The Check Part dialog box opens.
2. Click Objects and specify the parts to be checked:
◦ Click the part on the screen.
◦ Type the part name in the user input line.
◦ Select parts from the Structure Browser.
3. Click the Maximal check box to perform a detailed check on the entire part.
4. If necessary, set one or more of the following display options for the part checker:
◦ To label critical areas, click the Labels check box. Labels give the most detailed feedback.
◦ To display all information available, click the Verbose check box.
◦ To keep the labels after the check, click the Keep Lbls check box.
◦ To switch off warnings, fixed messages, and information messages temporarily, clear the Warnings check box. You may find it necessary to switch off messages when checking and labeling multiple parts to prevent the viewport from becoming too cluttered.
5. If Warnings and at least one of Labels and Verbose check boxes is clicked, you can click or clear the check boxes criteria (
min Edge,
Control points,
Void Shells,
Knife-edges) that are described above to include or exclude in part checks.
6. Click Check It to check the selected parts.
Creo Elements/Direct Modeling checks the parts, highlights any critical areas found, and reports the results in the Output window.
7. Continue to check the parts (or check other parts), or click to complete the operation.
Check Part. The Check Part dialog box opens.
