Synopsis

&ARROW

Description

Controls the type of arrowhead created for dimension arrows and leaders for all dimensions and drafting aids (see Figure 1-2).

You can control the arrowhead display of the arrows on a dimension independently. The first arrowhead type is identified as arrowhead 1 type and the second one is arrowhead 2 type. Use &ARROW to control arrowhead 1 type, and &ARROW2 to control arrowhead 2 type.

The size of the arrowhead is controlled by the GPA &ASIZE, which has an effect only when line, arrow, character size relationship is off. Use the GPA &DPREL to turn the relationship on and off.

Parameters

Parameter

Description

&CLOSED

GPA which indicates that closed arrowheads will be created.

&OPEN

GPA which indicates that open arrowheads will be created.

&ARCHCR

GPA which indicates that architectural arrowheads will be created.

&DOT

GPA which indicates that a dot will be created. The center of the dot will lie at the intersection of the dimension line and the extension line, or at the end of the leader. The diameter of the dot will be 1/10th of the arrow size (controlled by the &ASIZE GPA).

&ORGSYM

GPA which indicates that a dimension origin symbol will be created. The center of the symbol will lie at the intersection of the dimension line and the extension line. The diameter of the origin symbol will be the same as the arrow size.

&NOARHD

GPA which indicates that no arrowheads will be created.
