IFC Project#

Overview#

location Scene Properties > IFC Project Info > IFC Project

The IFC Project panel lets you create a new IFC project, load an existing IFC project, or view high level project metadata about the currently loaded project.

IFC Schema

Choose between which IFC schema version to use when creating a new project. IFC4 is recommended for all new projects.

Unit System

Choose between metric and imperial units of measurement when creating a project.

Length Unit

Depending on the unit system, choose the default unit to be used for all length measurements. Lengths are used for moving objects around in the 3D scene, as well as lengths, widths, height, and depth quantity take-off data.

Area Unit

Depending on the unit system, choose the default unit to be used for all area measurements. Areas are typically used for quantity take-off.

Volume Unit

Depending on the unit system, choose the default unit to be used for all volume measurements. Volumes are typically used for quantity take-off.

Template

Choose between starting a completely blank project with no objects, or with preloaded object assets (such as wall types, beam types, etc) that you can use immediately. The blank project is recommended for users who want to curate assets, whereas the IFC4 Demo Library is recommended for users wanting to experiment and learn with a basic set of objects.

This also shows other larger object libraries for steel and countries available with the BlenderBIM Add-on. These contain hundreds of objects and are not recommended to be loaded as a template.

You can start with a blank project and load in more assets later from a library using the IFC Project Library panel.

Create Project

Create a new project based on the selected settings and template. By default, your project will be created with a basic spatial structure, including a single site, a building, and a single storey within the building.

Load Project

Load an existing project from an IFC file. The IFC may come from any source, including exported from proprietary BIM software.

Project details#

Once a project is created, basic metadata about the project will be displayed, with basic features to save and unload the project.

FILE Filename

Shows the URI of where the IFC is saved, or “No File Found” if the IFC has not yet been saved.

GREASEPENCIL Enable Editing Header

Enable editing basic metadata about the project.

FILE_CACHE IFC Schema

Shows the IFC schema identifier of the model. This cannot be changed while the model is open. It is typically one of IFC2X3, IFC4, or IFC4X3. Other values are not standardised and not supported by the BlenderBIM Add-on.

FILE_HIDDEN IFC MVD

The Model View Definition (MVD) defines the intended purpose of the IFC model. “Design Transfer” is the most advanced MVD, meaning that IFC may be used for native authoring of the model. Other examples include “Reference View” for purely read only geometry (i.e. “dumb geometric model”) or “Coordination View” for coordinating models between different disciplines.

The Design Transfer MVD is used by all BlenderBIM Add-on projects, and is a superset of all other MVDs.

EXPORT Save Project

Saves the current IFC project to a file on disk. Note that this should be used to save the IFC project, not the regular Blender File > Save menu.

FILE_TICK Save Project As

Saves the current IFC project to a file on a disk with a different filename.
