Set Units in Template
Units can be set for the model and for the template.
Setting the model units affects the unit definition of the model (the model is converted to these units) and thus also the exported IFC file. If no value is given for a model unit, the unit defined in the imported IFC model is used.
The template units define the interpretation of any measure values used in the template. If no value is given for a template unit the model unit is assumed. Template units have no effect on the units of the exported IFC file.
