Functionalities for graphics creation of variants correspond to the mode of operation of standard CAD designs. A recorder is simultaneously running which records progress in work and samples the variable names. This reduces the integration workload to the minimum. In the preparation process, not only geometrical and text variables but also mathematical, algebraical and trigonometric computing operations are available. Building sections generated with Variant can be read into 2D or directly into 3D at any time. The entire geometry of the variant design is modified by the entry of the parameters which you have established. All parameters are entered as values or are extracted from the existing design. Typical fields of application for cadwork Variant are roof, shelf and shed designs, laminated constructions or groups of fasteners.
