SIFCEXPORT

The SIFCEXPORT command exports networks from the current drawing to IFC 4x3 ADD2, IFC 4x1, and IFC 4x0 formats.

Before using this command, see:

IfcExportAs - Which IFC class the device belongs to
PropertySet - Which properties will be exposed in the IFC file
Representations - How the device components will be represented in IFC
Viewers - Considerations regarding viewers and how they process geometries

To use it, call SIFCEXPORT via the command line, menu, toolbar, or the Ribbon.

In the screen that opens:

Configure:

Object
- Chord Height - The chord height of the arc when discretizing the curve
  Splines are not well supported in most IFC viewers, so SOLIDOS chooses to convert the SPLINE into a POLYLINE. Thus, the distance between the chord's midpoint and the segment's highest point relative to the chord is used to discretize this segment into an ARC section, where the arc's start, end, and midpoint lie on the SPLINE.
  It is similar to the "Mid-Ordinate Distance" used for Civil 3D surfaces.
- Use BREP - Indicates whether or not all solids will be drawn using triangulation
  Note: IFC viewers have certain limitations when representing geometry.
- IFC Format Version - Specifies the file format to be exported
  Options include:
  - IFC format 4.0
  - IFC format 4.1
  - IFC format 4x3 ADD2
  Note: Note that Navisworks may or may not be able to read the file, depending on your Navisworks version:
  - Navisworks 2023: The IFC 4x3 format is not supported, so use version 4x1
  - Navisworks 2024: The IFC 4x3 format is supported, but not "IFC 4x3_ADD2"
  - Navisworks 2025: The IFC 4x3_ADD2 format is supported
Project
- Project Name - The project name that appears in the exported IFC properties
- Project Description - The project description that appears in the exported IFC properties
Site
- Site Name - The site name that appears in the exported IFC properties
- Site Description - The site description that appears in the exported IFC properties

And click the OK button to process.

Tip: Before using this command, enable the log (SOLIDOSLOG command) to monitor potential export issues in the file (folder where the plugin is installed/SOLIDOS_LOG.txt)
