Command: rect

Syntax

{<entity> = } rect {<start>,} <finish>

Description

Create a rectangular polyline graphic entity.

Parameters

• <entity>
  An entity or gstructure identifier. The lines entity will be given this name.

• <start>
  A point phrase defining one corner of the rectangle. If omitted, the current position of graphic control is used.

• <finish>
  A point phrase defining an opposite corner of the rectangle. This may be an array of two point values, in which case the two points define both corners. In such a definition, the <start> parameter should be omitted.

Switches

• -alph=<num>
  An alpha transparency factor between 0 and 1. A value 1 implies fully opaque, 0 means fully transparent (therefore invisible). The default is 1.

• -br=<num>
  A brightness factor between -1 and +1. A value 0 means normal, -1 means very dark (black), +1 means very bright (white). The default is 1.

• -col=<color>
  The color of the lines. If included this overrides any color defined in the linestyle (-ls). If omitted, the value no_change is used.

• -fr=<num>
  Define a fragment number for the entity. If omitted the default fragment def_fragment is used.

• -g=<groups>
  The graphic groups of which the entity is to be a part.

• -ls=<linestyle | color>
  The linestyle of the lines. This can be a linestyle or a color. If omitted, the default modeling color (def_color) is used.

• -op=<ident>
  A point identifier into which the points of the rectangle are to be recorded. This option is not available when an entity is being created. If <ident> does not exist a new point array is created using current scope rules.

• -ra=<num>
  Define a rank for the entity. If omitted, the default rank def_rank is used.

• -th=<num>
  The thickness of the lines. If included, this overrides any thickness defined in the linestyle (-ls).

Notes

If the command has the form <entity> = rect, an entity is always created.

If the command has no entity assignment, then an entity will be created only if the -op option is not used, or the command is not within another entity creation block, e.g. lines, polygon.

Examples

Create an unnamed lines entity.

rect e:1000&n:1000

Create a named lines entity (the corners are defined interactively).

entity my_rect = rect pcur,pcur,-col=orange
