Identifier: gc

Type

point

Description

The current graphic control position. This is indicated in the current graphic window by a crossed-square symbol. When its value changes, the symbol moves accordingly.

The value may be changed by a user assignment, and is frequently changed automatically by the system during graphic entity definition. Most point and vector expressions use the value of gc as a base point for computing relative vectors.

The graphic control symbol is displayed in the current graphic window only, although it can be globally suppressed via the system numeric gc_display, or on a per window basis using the -no_gc switch on the wgraphic command.

Examples

Set graphic control to a known position.

gc = (500,500,1000)

Permit the operator to position graphic control using the mouse.

gc = pcur
