To Create a Motion Analysis Feature
1. Click
Analysis >
Analysis. The
ANALYSIS dialog box opens.
2. Under Name, specify a name for the analysis or accept the default name.
3. Under Type, click Motion Analysis.
4. Under RegenRequest, specify the regeneration option by clicking one of the following:
◦ Always—Always regenerate the analysis feature during the model regeneration.
◦ Read Only—Exclude the analysis feature from the model regeneration.
◦ Only Design Study—Regenerate the analysis feature only when it is used by a design study.
5. Click Next to create the Definition part of the analysis. The Motion Analysis dialog box opens.
|  For an assembly running a model analysis, you need to ensure that the absolute accuracies of the component parts are not significantly different. If the accuracies are significantly different then the interference or clearance involving the component parts can not be carried out for the assembly. |
6. Under Parameters, select the parameters that you want to compute.
7. Under Options, select from the following:
◦ Use all moving parts—Create a motion envelope using all moving parts. If you do not want to include all moving parts, clear this option and select the parts individually.
◦ Create motion envelope—Show the motion envelope for all or selected moving parts.
◦ Envelope quality—Enter the number for accuracy of the display of the quilt that represents the motion envelope.
◦ Update interval—Enter the number of frames between two update events. The number of frames determines how often the system updates the graphical results of the computation.
8. Click Run to begin the analysis. The system shows the moving parts in motion, computes the values of the parameters that you have included in the analysis, and shows the graphs. The number of computation points for the analysis depends on the number of frames in the motion definition.
The results of the computation appear in the Results box. For each parameter, the system computes the minimum and maximum values, and the time when these values were reached.
9. To view the results in a separate information window, click Info.
10. To change the display settings for the motion envelope, click Display.
11. Click Close to return to the ANALYSIS dialog box. The Result params window opens. The parameters associated with the measurement appear in a table under the headers Create, Param name, and Description.
12. To create a parameter, select it from the Result params list, and click YES under Create.
13. Under Param name, accept the default name or type a name for the parameter.
14. If you selected the option Create Motion Envelope, click Next (otherwise go to the last step). The Result datums window opens, listing the quilt.
15. Click YES under Create to create a quilt feature.
16. Under Datum name, accept the default name or type a name for the feature name.
17. Click OK to finish.
