Motion Simulation: Calculate Motions 
/ Analyze Collisions 
Access:
To calculate the motions, select the Calculate
Motions button from the Motion
Simulation dialog.
To analyze a collision, select the Analyze
Collision button from the Motion
Simulation dialog.
The Calculate Motions option is only available in Motion by Collision Analysis mode, and calculates all the motions that are not calculated or are calculated but not updated.
The Analyze Collision option is only available if a collision was detected. The option is automatically invoked after a Calculate Motions operation, if a collision was detected.
Calculate Motions
Calculate all the motions that are not calculated or are calculated but not updated. This option is only available in Motion by Collision Analysis mode.
During the calculation process, a status bar and also a vertical line moving across the grid, inform you of the progress, as shown in the image below.
Note: For an explanation of the various colors appearing in the grid, press the Legend 
button to display an explanatory dialog.
If a collision is detected, a message is displayed informing you that the motion was stopped due to a collision, and a red vertical line in the grid indicates the moment of collision, as shown in the image below.
Upon closing the message, the Calculate Motions mode is exited and the Analyze Collision mode is automatically invoked; see below.
Analyze Collision
This option is only available if a collision was detected. The option is automatically invoked after a Calculate Motions operation, if a collision was detected. When invokedinvoked manually, the system will choose the closest Red line to the Blue line (if more than one red line exists (in different ranges)). The Collision Data dialog is displayed enabling you to analyze the collision.
The collisions are displayed per checked display option, as shown below (with the No Highlight option, nothing is highlighted):

The Previous Step 
and Next Step 
buttons are also displayed to view the motion steps before and after the collision.
When closing this dialog, the previous display state is restored.
