IFC Improvements

Building Coordinates and IFC

Location of the building in IFC import

You can select how to locate the imported IFC model in the project.

You can select from the following options:

  • Locate to IFC-site origin: The building is located based on the site origin of the IFC file. The coordinates in the field show the building location measured from the project origin (0,0,0).
  • Locate to site origin of project: If the site origin has been defined, the site origin of the IFC file is located to the site origin of the active project. If the site origin of the project does not exist, selection is disabled.
  • Locate to building origin of project: The building in the IFC file is located to project origin (0,0,0).
  • Rotate building to north direction: This is an optional selection. If north direction has been defined in the IFC file, you can import the building rotated in the north direction (IFC north is parallel to the project's y-axis).

Save geographical coordinates in IFC import

You can import geographical coordinates to the live building model when importing an IFC model. Geographical coordinates are imported as data and they can be utilized in IFC export or when exporting to Google Earth using DAE format, for example. Altitude affects also the building drawings, if height symbols with absolute heights are used in elevation and section drawings.

Simplified coordinate tools

This feature is not only related to the IFC model, but it closely affects the import and export of the IFC model. Therefore, it is worth mentioning here. The site and building coordinates are now collected in a single dialog box. The tool for editing building coordinates can be found from project settings:

The site and building coordinates are now collected in a single dialog box. You can define the north direction and the location of the site origin either by entering numeric values or by clicking points in 2D or 3D.

Use the origin of the imported IFC model in export

You can use the origin point of the imported IFC model when exporting the building to an IFC file. You can use this feature when you have only one imported IFC model in the project.

Conversion Tools

Create conversion rules

There is now a library for IFC conversions. You can define conversion rules for walls and profiles. You can also specify type conversions. The library can also be project-specific. Standardized conversion rules are especially useful with standard partners, when structures as wall types are similar from one project to another.

The Custom Library user interface is on the System tab.

When starting to use conversion rules, create own custom specific library for them. You can copy, add and modify rule sets there.

Build Vertex BD object from IFC object

You can selected change IFC parts to Vertex parts. For walls and profiles is possible to use saved conversion rule sets. Sets can be select from the library or you can create new project specific set or use the existing project specific set (similar selection with library sets).

Project-specific conversion sets

Project specific set can be created in conversion dialog. When you press button Create conversion rule in Convert objets dialog, system creates automatically project specific library and add set there. Those sets are also visible in libary interface, when project is active.

Other IFC Tool Improvements

Move a building

You can easily move the entire building if it has been imported in the wrong location. This is possible, if an incorrect origin has been written to the IFC file. After you move the model, the system will remember the new location even when you update to the latest version of the model.

Selection Filter for IFC parts

You can easily filter IFC objects when selecting them based on IFC data. Mass selection is especially important when hiding objects or converting them to Vertex BD objects. Different types of objects are visible in the object list of Selection Filter. Using additional settings, you can select the filtering criteria. Material and common parameters are visible by default. You can also set all property sets visible. (This feature has been published in Vertex BD 25.0.02)

2D presentation of the imported IFC objects

You can now add 2D geometry for IFC objects. You can select the component types for which 2D representation will be added. You can change the presentation afterwards by selecting objects and then the presentation from the context-sensitive menu. 2D presentation slows down the import process. Switch it on only for the object types that are needed in 2D. (This feature has been published in Vertex BD 25.0.02)

IFC import is much faster than earlier

IFC import is significantly faster than before. The amount of acceleration depends on the content of the IFC model. At best, acceleration is from hours to minutes. In the new version, it is now also possible to configure 2D representation for components. Creating a 2D representation of a 3D model will slow down the import process somewhat. So you should consider what is represented by default in 2D.
