Blender 2.8 modeling: Three-point arches for architecture

In architectural modeling, it is common to have a few shapes using arches like windows and doors. If you have to create such models in Blender, you will have to use the Spin tool to create such the main shape.

Unlike CAD design software that offers a wide range of options to create arches, like the ones you have in AutoCAD, we have to find all our solutions for modeling with the Spin.

The Spin tool can do a lot for us, and if you know how to handle the 3D Cursor to set the radius for the arch, you will be able to create all kinds of round shapes.

However, using a free Add-on for Blender 2.8, we can include another option to create arches in Blender. With the Three-Point Arch Tool from a developer called “n-Burn,” you can create arches using point references and not only the 3D Cursor.

You can download the Add-on from this link, which offers versions for both Blender 2.8 and 2.7x.

If you want to learn how to use the Spin tool for architectural modeling, we have a full section explaining the tool in our Blender 2.8 for architecture book. There you will also find several references regarding modeling for architecture using Blender 2.8.

You can get the book in both digital and paperback versions.
