[4] Caddie was created by Anthony Spruyt, an architect from Pretoria, South Africa, in 1985 and was originally called Michael Angelo.

[5] The first release version was called Caddie and fit on a single 360 kB floppy disk, and was designed for the IBM Personal Computer XT.

Caddie was one of the first CAD tools that utilised microcomputers and did not require a mainframe computer with workstation access.

AEC - the smart tools for creation and editing of 2D and 3D Architectural, Engineering And Construction intelligent objects such as walls, windows, doors, openings, slabs, roofs, trusses etc.

The application includes tools for creation and manipulation of live long and cross sections as well as cut and fill volumes for site development.

For example, the SA Arch module contains tools for doing live SANS 204 Energy efficiency calculations[18] now required when submitting building plans in South Africa.

Mech - automated tools for the creation of commonly drawn mechanical objects such as nuts and bolts, machining and geometrical tolerancing symbols, steel beams and angles, gears, sheet metal developments and welding symbols.

Civil - tools for the creation of common symbols used on GA drawings, long sections, turning circles pipe layouts etc.

[20] Caddie was originally developed in South Africa in 1985, and it quickly established a significant presence in its home market.
