IFC exchange using ESTmep, CADmep

To create an IFC file within ESTmep or CADmep, you have to be sure to choose the correct format for the application. in other words the format will vary for Autodesk Navisworks or Tekla BIM sight. 
IFC Selection

Export to Navisworks


By using the command “export 3D” (shortcut “EX3D”), you can choose one of these formats.

  • IFC-XML Binary Files (*.BIX)
  • IFC-XML Zip Files (*.ifcZIP)
  • IFC-XML Text Files (*.ifcXML)
  • IFC Step Files (*.IFC)
For Navisworks the best format is “IFC Step Files (*.IFC)”.
You can see in the image below the Navisworks pipe properties.

If you also use CADmep, the command is “IFCE”. The file selector is the same and the result will be the same

However, I recommend you use the DWG format. When you open the CADmep (DWG) file in Navisworks the properties appear in the “CADMEP+” tab, where you will find more properties. See image below :

Note : To see the CADmep+ tab in Navisworks you need to install the Autodesk Fabrication CADmep 2014 Object enabler .

Export to Tekla BIM sight

When you open an” IFC Step File (*.IFC)” within Tekla Bim Sight, if you click on one element, the result will be as shown below:
IFC step files BIM sight Tekla

If I export the same file as either “IFC-XML ZIP Files (*ifcZIP)” or “IFC-XML Text Files (*.ifcXML)” , then you click on one element, the result will be as show below:

Personally I prefer this format,  since with this method I know the selected object is an elbow and there are more attributes.
