Primitives such as cubes, cuboids and pyramids can be easily created and edited to be scaled and placed on the 3D world.

Colours can be selected for individual elements, making the free roaming worlds more varied and complex.

The user-created virtual world is divided into areas, reducing the processing power required to render objects.

In order to make games rather than worlds, 3D Construction Kit also allows for the addition of conditions, using the very simple-to-program Freescape Command Language (FCL).

Elements such as proximity sensors triggering events, enemies making the player appear in another zone of the game when hit, and the ability to activate switches in order to open doors, make the worlds created with 3D Construction Kit come to life and add a level of uncertainty to the gameplay.

3D Construction Kit was originally released for the Amstrad CPC, ZX Spectrum and Acorn Archimedes in May 1991.

The 3D Construction Kit packages came with a 30-minute video tape, featuring an introduction and a tutorial presented by Ian Andrew, the original designer of the Freescape system.
