A coordinate design and information system (CDIS) combining coordinate geometry, spatial features and drafting into one package. CDIS uses an object-oriented and spatial-based approach in which all objects have a set of attributes, while space and areas are defined and tracked.

The invention has such features as incremental numbering with automatic parceling, duplicating a cluster, pulling a line tangent to a curve, erasing figures by type, converting lines to polylines, computing an average radius from digitized points, wiping out triangles greater than a certain length, exploding a text file inserted as multi-line text into individual lines of text, and specifying parcel report precision.
