IFC - AISC Steel Detailing MVD format

IFC - AISC MVD EM.11 format

• IFC - AISC Steel Detailing MVD format:

The function of the model is to provide enough detailed information about the steel members to enable the fabricator to manufacture the steel pieces. The model is the finalized version of "Advanced Steel Detailing Model" which is provided as the output of any modification and integration of the final detailing model.

The exchange model includes all the finalized information of "Advanced Steel Detailing Model", like the member ID, and member properties (section size, grade, length) detailed welding and bolting information, information about holes and member camber, etc. for all main and minor members.

The IFC - MVD format is a specific output developed for the U.S. market, by AISC in collaboration with GeorgiaTech, intended to deliver information from Steel detailing software to CNC machines in order to enhance the fabrication process and deliver a standardized format that can be understood by both the software exporting it and the CNC machines.

The format output is based on the IFC 2x3 scheme definition.

The implementation made in Advance Steel 2016 R2 is based on the current requirements for export, and includes the following:

• Beams:
  • With features
  • With mirror
  • Any shape:
    • Standard shapes are defined through parameterized IFCSHAPEDEFINITION.
    • User shapes or non-standard Advance Steel shapes are defined as IFCARBITRARYPROFILE.
  • All the required AISC_EM11_Pset attributes.
  • Beams have a ProfileMap that allows sharing of identical shape definition for multiple beams that have the same section class and section name.
• Plates:
  • With features
    Note: Corner cuts are not exported as cuts (VOIDS), instead they are included in the Plate outer shape, inside the IFCPLATE extrusion definition.
  • Any shape through Polylines/ TrimmedCurve + extrusion .
• Beam and plate special classification:
  • Horizontal beams are always IFCBEAM.
  • Vertical beams are always IFCCOLUMN.
  • Skewed beams are IFCMEMBER.
  • Plates and beams thet are attached parts in assemblies are IFCDISCRETEACCESORY.
• Fasteners:
  • Welds as fasteners
  • Bolts as mechanical fasteners
  • All the required ISC_EM11_Pset attributes
• Compound beams:
  • Components of a compound beam are exported as individual objects connected through an assembly.
• Assemblies
