The Vernier calipers were created with the Standard version (V8) of TurboCAD (Standard was later to become known as Deluxe). The calipers, like so many models developed in TurboCAD, were created by extruding 2D profiles of the various components into 3D objects. Text was applied using the Text tool which was then converted into 3D objects for rendering purposes. As with all early Standard models, line color and standard lighting were the only option when setting up for a rendered image.
