So you’ve been asked to provide an IFC file, and not sure how to organise your data in 12d Model prior to exporting.  Here is a quick reference guide for all the humps, bumps, and hurdles we’ve come across for getting your data out to the wonderful world of BIM.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator border_width=”5″][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Before proceeding, there’s one important question you should ask first;

  • What software package is the data going into?

If the answer is 12d Model, then we can’t stress enough that you should be using a 12da/12daz file.

If the answer is something else, then read on…[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator border_width=”5″][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Some things to be aware of;

  • Not all software reads all versions of IFC files.
    • You should check this with the receiving person.
  • The IFC format only allows for String Attributes.
    • IFC files do not support Segment and Vertex Attributes.
    • This is a limitation of the IFC Format.
    • This is not a problem with 12d Model.
  • Super Alignment and Tin can only be exported as IFC4x1 or later.
    • IFC2x3 / IFC4 do not support Super Alignment or Tin
    • Again, this is not a problem with 12d Model.
