Rectangle
Alias: R E C
Creates a rectangular closed polyline from two opposite corner points.
Description
The Rectangle command draws a closed rectangular polyline by specifying two diagonally opposite corner points. The result is a single polyline object with four segments.
Workflow
Type
R E Cand pressSpaceorEnter.Specify first corner: Click a point on the canvas or type coordinates.
Specify opposite corner: Click the diagonally opposite corner, or type dimensions relative to the first point (e.g.
@100,50for a 100×50 rectangle).
Tips
Use relative coordinates (
@width,height) to create a rectangle of an exact size from the first corner.A rectangle is a closed polyline and can be exploded into four individual line segments.
Rectangles work well as boundary areas for Hatch.
DXF Representation
A rectangle is stored as a closed LWPOLYLINE entity in the DXF ../dxf BLOCKS section — the same entity type as Polyline but with the closed flag (group code 70, value 1) set and exactly four vertices.
