Description

The article describes how building structure can be prepared and how the created structure can be verified. There are several ways the building structure can be prepared for a project. The choice of the method depends on what source data on the structure and storey plans are available and on the scope of the design to be made. If the scope of the design does not include calculation of heat losses according to standards, then rooms can be represented in the plans as polygons with no cooling partitions. Each storey constitutes a separate plan drawing sheet.

Import underlay

  • Icons of components and functions related to importing underlays (base drawings) are available in the 2D Editor window on the Main tools bar in the Underlay section when the Underlay editing scope is enabled.

Examples of use

Manual creation of building structure

Storeys

  1. Create the required storeys and append their data. The movie shows creation of two sets of storeys.

Underlay

Underlay (base drawing) is a two-dimensional (flat) graphical object retrieved from an external raster or vector file. The underlay itself does not provide building structure components, but it enables manual creation thereof adapted to the actual state of the building.
For more information, see: Import files

Room - manual creation of rooms

  1. Create a Room manually using a contour line

or by drawing a diagonal line. When a room is created by drawing a diagonal line disable the ORTO operating mode. After drawing the diagonal line complete the edition by right clicking.

Room - identification within area bordered with drawn partitions

Rooms can be created automatically in areas bounded by edges (surfaces) of the defined graphical partitions (walls, floor slabs, roofs). In this case it is necessary to draw graphical partitions in the project and to run Computation of building structure , which also enables adapting the partitions to the drawn plane of the roof.

  1. Place a series of Wall components by entering at the start the thickness of the wall in Data table and moving the cursor along the internal edges of the walls on the underlay. In underlays retrieved from a DWG file make use of the snapping to indicated layer feature. After placing Internal walls insert External walls in similar manner.

  2. Place the following components: Window, Door, Opening in wall, Recess.

  3. Place the following components: Slab. Outline of one storey is by default covered by a single slab.

  4. Insert: Roof.

  5. Create a multifaceted roof.
    For more information, see: Preparation of building structure - Creation of roofs with different construction
  6. Insert components Roof window

  7. Insert components: Opening in slab.
    Opening in slab can be deleted by clicking Delete-ikon.png

  8. Carry out Computation of building structure .
    Computation of building structure launches a number of operations associated with providing a complete building structure:
    • cutting away partitions by the roof plane,
    • automatic identification of rooms.

  9. Number the rooms.
    • Symbols are assigned to rooms by selecting Symbols assignment and marking room labels in a desired sequence. That sequence defines the numbering order of the rooms.

    • The program enables configuring the pattern of room numbering.
      The numbering configuration shown below means that the room symbol consists of a storey symbol and of a two-digit number of the room on that storey. More information is displayed when the mouse cursor is positioned over Question-mark.png.

Manual editing of rooms and automatic identification of walls and slabs on an underlay

The operation of automatic identification of walls and slabs enables creating these partitions within spaces identified between rooms included in the project and the outline of the building.
To carry out the operation:

  1. In the project file with previously inserted rooms, make a building outline using the 'Building outline' function.
  2. Optionally: if the building outline is identical on a number of storeys, enter appropriate values in the fields 'from storey' and 'to storey' in the data table of the building outline component.
  3. Launch interpretation of external and internal walls and slabs based on rooms arangement and building outline using the Automatic walls, slabs and roofs function.
    5.Automatic walls, slabs and roofs


Importing a complete building structure

Importing a building structure from a BIM (gbXML) compatible format

For more information, see: Import files

Importing a building structure from an InstalSystem 4 (ISB) project file


If necessary, manually correct or append the missing or incorrect components of the building structure thus obtained using the methods described above.

Verification of the correctness of building structure

Carry out the verification in the 3D view window
