If you have SOLID65 elements in your model, you can issue the PLCRACK command to determine which elements have cracked and/or been crushed. Small circles are shown where the concrete has cracked, and small octagons are shown where the concrete has been crushed.
The cracking and crushing symbols are visible when a non-hidden, vector type of display is used. To specify such a device, issue this command:
/DEVICE,VECTOR,ON
