• Building parts with layers

  Straight and curved walls with mitres and T-joints, slabs with openings, roofs over any outline with dormers and roof windows, straight, winding and spiral stairs, columns, beams and curtain walls.

• Materials with properties

  Thermal conductivity and density per material. From these Linework works out the U-value (the method of EN ISO 6946) and the weight per area of every type.

  materialwalltype

• A model from the 2D plan

  A drawn floor plan (DWG, DXF or vector PDF) becomes walls, openings, rooms and storeys, each with a preview. Duck proposes and asks.

• Permit drawings

  Site plan with setback areas (worked out the way the German model building code does, values adjustable), plot ratio and floor area ratio, north arrow, materials in the elevations. All sheets into one PDF, PDF/A on request.

• Working drawings

  Working drawings at 1:50 and details at 1:20 from the same model: structural dimensions, layers hatched by material, build-ups on leaders, window and door schedule by position.

Conversions and existing buildings

• Existing, demolished, new

  Every part carries its phase. The existing, demolition, conversion and new-build plans come from one model, demolition in yellow and new in red, as German permit drawings ask for. Rooms and areas exist before and after the conversion.

  renovationroom

• Demolition quantities

  Per material in cubic metres, tonnes and skips, including what new openings take out of walls that stay.

  demolition

• Survey and photos

  A room from a hand survey (sides and diagonals), plans and scans as an underlay at scale, photo points with viewing direction and a photo list.
