A building block represents the outer shell of the model or part of the model. A finished block comprises a set of building elements, which may include external walls, roofs and floor slabs, the constructions of which are determined from the current building construction model data. Similarly, using opening model data, block facades are automatically created with the required configuration of windows, doors, vents and solar shading devices:
Solar shading devices are displayed in the visualisation screen:
A block may be divided internally into any number of zones by drawing partitions and where needed, voids or courtyards can also be incorporated:
Custom openings (windows, doors, etc.) can be added to block facades by going to the surface level and using the 'Draw window' family of commands:
Blocks can be moved, copied and rotated. Blocks can also be cut or stretched and block faces can be dragged to different positions.
