Group Example

This example demonstrates the creation of two groups from several previously defined objects, as well as how to assign a name to a group using the EDA &NAME.

$$
$$ Declarations
$$
    ENTITY/LN(4),CR(2),GRP1,GRP2
$$
$$ Geometry Definition
$$
    LN(1)=LINE/-1,-.5,1,-.5
    LN(2)=LINE/1,-.5,1,.5
    LN(3)=LINE/1,.5,-1,.5
    LN(4)=LINE/-1,.5,-1,-.5
    CR(1)=CIRCLE/0,0,.5
    CR(2)=CIRCLE/0,0,.25
$$
$$ Group Definition
$$
    GRP1 =GROUP/LN
    GRP2 =GROUP/CR,GRP1
    &NAME (GRP2)='GROUP_2'

NOTE: GRP1 which consists of LN(1) through LN(4), becomes a subgroup of GRP2. The EDA &NAME allows you to assign a name to the group as an attribute.
