DWGTEXTHCSENDCAPTOP1

This variable applies to the following attributes.

"ENDCAP_LEFT_PROPERTIES_1"
"ENDCAP_RIGHT_PROPERTIES_1"
 

With the help of different variables, you can add a text string and the following symbols, $A $B $L1 $L2 $L3 $L4 $C, to get some additional information.

$A, $B, $L1, $L2, $L3 & $L4 are taking the length from the endcap definition, and $C writes out which cores are affected. 

When "Top" is selected then some of the symbols are included, $A $L1 $L2 $C. Therefore the custom name includes a name and some of the chosen symbols.

This endcap was placed on the right which triggered "ENDCAP_RIGHT_PROPERTIES_1"

DWGTEXTHCSENDCAPTOP works the same way and the attribute that is trigged is called "ENDCAP_RIGHT_PROPERTIES"
