• New buttons Graphic grid (grid view) and GNET (snap mode for the grid view) in the blue status bar - additional program modes for working with the drawing grid visible in the 2D editor, making it easier to draw and align elements precisely (watch video):
  • The grid automatically adjusts to the view scale, and the cursor can move in steps (GNET mode, shortcut CTRL+G to toggle) according to the grid spacing
  • GNET mode is compatible with existing AUTO/ORTO modes and drawing with CTRL/SHIFT, which alternately enable or disable these modes
• Added snapping to characteristic points of polylines - including Midpoint, Perpendicular, Endpoint, Nearest and Ortho snap points [screen]:
  • Control of active snap types is available in the AUTO/ORTO mode settings
• Extended the Select from area... function with a new option: selecting elements only from the active floor level (main, additional, or internal) [screen]:
  • The new option is available as a separate button in the Project browser - visible only in projects containing more than one level per storey
• Added separated ranges in the Project browser:
  • Existing Building structure has been divided into: Building (rooms view) and Building (building elements view)
  • Existing Heat load calculations have been divided into: Partition definitions, Definitions of thermal bridges, Building (partitions view), Building (ventilation zone view) and Building (thermal bridges view)

Building structure

• Added a new field in the room data table - Usable floor area [screen]:
  • The Usable floor area can be calculated automatically in rooms with sloped roofs. Height thresholds for inclusion and percentage values can be defined in General data under the Room data tab, according to national standards and regulations
  • For multi-storey rooms, the Usable floor area is calculated as the sum of the areas of all floors meeting the height criteria
• Separated Volume (gross) and Net volume into two independent fields in the Data table [screen]:
  • In the General data window, under the Room data tab, a switch allows the user to choose which volume (gross or net) to use in calculations

  • This function works with the GNET mode - movement occurs in fixed steps according to the grid settings
  • Supports moving single or multiple rooms simultaneously
  • The operation is available only for manual rooms (and the building outline) and requires an active GNET grid
  • Room label moved only using the four-arrows icon - prevents accidental movement of manual rooms during editing (behavior of other labels unchanged)

• Added the ability to configure the graphic style of the False ceiling and Floor
• Introduced several improvements and bug fixes across various areas related to the editing and compilation of the building structure

  • If the Building thermal calculations module is enabled and used, then in the general data of all types of radiant systems it is possible to declare that the thermal resistance of partitions on which heating or cooling partition zones are located, should be taken from the partition definition declared in the HL module. This will give values closer to the actual heat losses of surface heating or cooling systems to the environment, and will also change the selection of additional insulation layers [screen]
