Reverse.lsp Version 3.0

Reverses all line, arc, circle, ellipse, spline, polyline, and lightweight polyline entities.

Circles, arcs, and ellipses are converted to polylines; other objects retain their respective entity type. Circles and circular arcs are rendered as heavyweight polylines if the system variable plinetype = 0, or lightweight polylines if plinetype > 0. Ellipses and elliptical arcs are rendered as high-resolution, curve-fit polylines with up to 64 exact vertices and tangents.

Reverses all text entities including single-line text, attributes, multiline text, dimension text, and remote text. Fonts with leading or trailing white space, and text styles with upside down, backward, or vertical effects are fully supported.

Rotates all hatch patterns 90° counterclockwise. Rotates all gradient fills 180°. Solid fills are ignored.

Single-line text, multiline text, attributes, hatch patterns, and gradient fills may be reversed within blocks. All other block components are ignored. Nested blocks are not supported.

Preserves color, layer, linetype, linetype scale, plot style, lineweight, thickness, elevation, global width, and text style properties. Preserves circular, quadratic, and cubic fitting. Preserves vertex bulge, segment width, and vertex tangent.
