Starting conversion in Viswalk

The conversion process may take a few minutes, depending on the data volume. The conversion is run in the external IFC2INPX_GUI.exe application. It is not run in Viswalk. This allows you to continue to work in Viswalk during the conversion process. IFC2INPX_GUI.exe is stored to the ..\IFC2INPX directory of your Viswalk installation.

1.  On the File menu, click > Import > BIM (*.ifc).

The IFC Converter for Viswalk window opens.

2.  Make the desired changes:

Element Description
Source file *.ifc file that is to be converted to an *.inpx file.
Target file

*.inpx file that is created by a conversion

Intersection height (in m)

The height above each imported level that runs in parallel to the base area in which Viswalk checks the building model's vertical subcomponents in terms of openings in order to identify window/door openings and obstacles. Default 1.00 m

Chord tolerance (in mm)

Viswalk uses polygons for modeling circular objects in IFC. The chord tolerance value specifies the maximum distance between the edges of the polygon and the actual circle before creating an additional corner point. Default 10.00 mm

Creating display types using materials

Creating a display type using each material imported.

Stratifying slabs

Modeling sloped ceilings or floors based on the BIM by stratifying the resultant pedestrian areas. Multiple pedestrian areas with different Z-coordinates are created. The attribute Stratum height (in m) defines the vertical distance.

Stratum height (in m)

Indicates height of the terrace. For floors above the base area. Default 0.10 m

Imported property sets as user-defined attributes

Creating user-defined attributes based on the IFC property sets.

Import as pedestrian areas

Floors (IfcSlab): Selecting floors to create construction elements based on the network object type pedestrian area.

Import as obstacles

Selecting the following subcomponents to create construction elements based on the network object type Obstacles:

  • Walls (IfcWall, IfcWallStandardCase):
  • Windows (IfcWindow):
  • Columns (IfcColumn):
  • Curtain Walls (IfcCurtainWall):
  • Plates (IfcPlate):
Import as stairs

Stairways (IfcStair): Selecting stairs to create construction elements based on the network object type Stairs.

Import as ramps

Ramps (IfcRamp): Selecting ramps to create construction elements based on the network object type ramps.
