New Schematic Geometry Wizard

The new schematic geometry wizard offers a quick start and simplified approach to geometry and model creation.

Enter building orientation & footprint (building type, shape, storeys etc.) and an entire model is prepared for you in one click.

Solar Algorithm Enhancement

SunCast and ApacheSim have been enhanced to enable solar tracking through non-connected zones and translucent shades.

  • Translucent surfaces, such as glass brise soleil, can now be modelled
  • Algorithm can track the path of the sun through non-connected zones – previously only possible through connected zones
  • Meshes or lattice shading devices can now be modelled with a single transparent surface, drastically reducing computation and modelling times
