A common question is how do you add a door to a geodesic dome?
I have no experience of adding doors but I can share the results of my research
To add a door to a dome, you need to remove either a pentagon or a hexagon from the base. In these 2 examples I’ve removed the pentagon because I think it should have a slightly smaller impact on the structural forces
Example 1: the door is not vertical
Example 2: the door is vertical.
In these cases, horizontal uprights are required
Here are a few examples I found on the internet (without the Domestar connectors)
Example 3: by simply removing 2 triangles.
You can then easily create a door with 2×2 hinges
