Create a clash analysis
A clash analysis is a clash check that you save with an assembly and run whenever you want. The analysis is created in the structure browser under the assembly to which you assigned it.
The blue clash analysis icon in the Structure Browser indicates that the analysis is up-to-date with the current assembly. A green icon indicates that the analysis is out-of-date. Right-click the icon to recalculate the analysis.
To create a clash analysis,
1. Load the assembly or assemblies in Creo Elements/Direct Modeling.
2. Click Analysis and then, in the Verify group, click Create Analysis. The Clash Analysis Define dialog box opens.
3. Select an Owner for the clash analysis. The analysis is assigned to this assembly in the Structure Browser.
4. Select a Name for the clash analysis. The default name is ca1, 2, etc.
5. Click Accept.
6. Select from the following options:
List vs. List: Calculate clashes between the parts specified in the Select List1 and Select List2 boxes. Choose this option if you want to run clash between two or more parts. Use the select tool to select multiple parts for each list.
All in List: Calculate clashes among all parts specified in the owner list.
Config: The clash analysis configurations window appears with a list of possible configurations. Check the clash analysis configurations you want to analyze in the clash analysis configurations window.
Results: All, clashing only, or touching only.
Press Fit: Ignore parts marked as press-fits.
3D Lib: Ignore library parts.
Thread: Ignore threaded parts and holes. If unchecked, properly fitting threaded parts and their corresponding holes will not cause clash issues. Only an improper fit or parts that are not identified as threads and holes will cause a clash issue. The parts must be created or modified so the inner and outer threads are identified. Parts created with 3D Library, Advanced Machining, Creo Elements/Direct Mold Base, or custom functionality will meet this criteria.
Clearance: You can specify a clearance value and all parts positioned within the clearance will create an issue in the results. The Results must be set to All to detect clearance issues.
Exclude: Exclude specific parts or assemblies from the analysis. If you are using the List vs. List analysis option, the excluded part list is applied to both lists.
7. Click Calculate. The results appear in the Clash Analysis Issue Browser. To reopen this browser, right-click the clash analysis icon in the Structure Browser and click Show Clash Issue Browser.
Click File > Settings > Clash Analysis. The Clash Analysis Settings dialog box opens. You can change the default part selection colors in this dialog box.
Limitations and restrictions
The clash analysis must be owned by a named assembly, not the default root assembly "/" or a selective instance of the assembly. If a selective instance is created after the clash analysis is defined, a red clash analysis icon will indicate that the analysis is invalid. Attach the clash analysis to a valid owner and recalculate the clash.
Only configurations below the analysis owner in the structure can be selected for clash analysis. To see a list of available configurations, check Configuration in the Create Analysis dialog.
