IFC – 12D Wiki Beta Test

Read IFC

When coordinating designs with Architectural, Structural, or Mechanical elements, the best format to receive their data is an IFC file. If you need to export an IFC file, please see here: Write Infrastructure IFC The IFC Express Reader currently supports IFC2x3, IFC4x1 and IFC4x3. IFC Spatial Structure is not currently read in by the IFC [...]

Read IFC – General

General Split data into entity models If the attribute IfcEntity exists, Models will be created based on entity type. Presentation layer as model If the IfcPresentationLayer exists, Model names will be based on the Presentation Layer name. The Presentation Layer takes precedence over 'Split data into entity models'. Any data not part of a [...]

Read IFC – Alignment

Reverse calc parts For any IfcAlignments, 12d will attempt to create Horizontal and Vertical parts for the Super Alignment from the with IfcHorizontal and/or IfcVertical Geometry. Copy alignment When Reverse Calc Parts is ticked-on, before attempting to create the Super alignment, a copy of the IfcAlignment will be made with the suffix ‘copy’ added to [...]

Read IFC – Unit

The incoming data will be converted into the units specified by the Convert length unit to. For example, Architectural data that is usually in millimeters can be converted to meters during import. This avoids having to manually scale the data in 12d.

Write Infrastructure IFC

Industry Foundation Class files, commonly known as IFC, have become the industry “standard” for sharing data between different software platforms. The main goal of IFC is to provide an open format, that removes the need for organisations to require the use of unpublished propriety files. As the IFC format is open source, and software [...]

Write IFC – General

General Most of the General tab is fairly self explanatory; Version Just use the latest. IFC4x3 onwards has greater support for Infrastructure entities. Format Before using XML or ZIP formats, check that the receiving software can read the file. IFC STEP - most commonly used format IFC XML - larger file size, but more 'readable' [...]

Write IFC – Placement

For a long time large structures, such as buildings, existed on drawings with a base-coordinate of 0,0. And that was ok. Until BIM came along... Now, with increasing requirements for Federated Models, these structures need to be coordinated with Civil data that has always been placed in real world coordinates. So it's time to put [...]

Write IFC – Attributes

Attributes are where the magic happens. But, as a 12d Model user you already knew that, as attributes have existed in 12d forever. Before continuing, you should be familiar with IFC Property Sets and how they are setup in 12d. Most of the settings below rely on attributes groups being setup correctly. Attribute Manipulator and [...]

Write IFC – Water

So lets be clear, you do not need to convert your Drainage Network to trimeshes. In case you missed it, you do not need to convert your Drainage Network to trimeshes. You can confidently export the Drainage Network to IFC. Export entire water network Yes, you want this ticked: on Unless you have a reason [...]

Write IFC – Project

Use Classifications Classifications attribute path Use Groups Groups attribute path - Path to attribute that provides the Group value. IFC Groups can be used to "group" objects together. For example, individual objects such as a road Sign + Post + Footing can be added to a single Group. An object may also be assigned to [...]
