BlenderBIM updates and new features: Version v0.0.210829

Blender 2.9: The beginner's guide

A significant amount of people think about Blender as a 3D modeler and platform to render realistic images to visualize your designs. It can help a lot in this regard, but that is only part of its role in architecture. With Add-pons like BlenderBIM, you can expand Blender and include authoring and document BIM data. That opens a world of possibilities for Blender to have an entire open-source workflow.

When using the BlenderBIM Add-on, you can create IFC files in compliance with ISO standards. A new version released recently has about 153 new features and multiple bug fixes!

Here is a list of the new features and bug fixes from version v0.0.210829:
