Synopsis

&CHAIN

Description

Controls object selection during automatic chaining operations.

Characteristics

Read/Write - Number - [1..4]

Constant Values

1 = &SIMPLE
2 = &CWCS
3 = &CWCSL
4 = &CWCSR

Parameters

Parameter

Description

&SIMPLE

GPA which indicates that the system selects the object which was created first when two or more objects with the same end point are found. The objects do not have to lie in the XY plane of the work coordinate system.

&CWCS

GPA which indicates that the system selects only objects which lie in the XY plane and selects them on the same basis as with the constant &SIMPLE.

&CWCSL

GPA which indicates that the system selects only objects which lie in the XY plane and gives priority to objects which are on the left side of the last object selected. If no objects exist to the left or if more than one object is found with the same end point, then final selection is done per the constant &SIMPLE.

&CWCSR

GPA which indicates that the system selects only objects which lie in the XY plane and gives priority to objects which are on the right side of the last object selected. If no objects exist to the right or if more than one object is found with the same end point, then final selection is done per the constant &SIMPLE.
