Is AutoCAD Civil 3D mature enough to allow for an accurate Import and Export of Industry Foundation Class (IFC) files?

@Onisuru Bobolo: What kind of accuracy are you referring to? Do you have any examples with tolerances that you used and were acceptable?

Sorry, for an Estimator 2D is more than enough. to do his estimate.

AutoCAD Architecture is IFC-certified for importing and exporting version2x3 IFC files. IFC files from versions2x2 and2x can also be imported if the data is compatible with2x3 and is consistent with implementation agreements as defined for the IFC2x3 coordination view

   civil3d is a specialized software for designing  and quantities calculations for roads an  d infrastructure

No it is not only enough 

Look to Kadiga BENBOUZIANE answer, and coordinate with her, she can help you and answer your question.

I think the latest versions can do that.

Autocad is a computer-assisted design and drawing software.

Therefore, it is intended for the design of all types of technical projects and the corresponding details and can be used for the transfer by import or export of certain files.

yes of course,AutoCAD CIVIL 3D Allows accurate import and Export of IFC files

Yes, it is possible thstCIVIL 3D mature enough to allow for an accurate import and export of IFC files
