Add a 'house primitive' to your scene - the parameters of these models are fully editable afterwards like any primitive.
Here is my House Primitive script for Blender. Its purpose is to create one or many building primitive(s) that will be editable anytime afterwards. Those primitives are based on precise parameters. It can be used both for urbanism, thermic studies, modeling...
The purpose of this primitive is to create a low-poly object "House", editable in both its dimensions and in its advanced settings:
- number of floors.
- flat or pitched roof
- height of floors, thick slabs
Moreover, it is possible to modify the object afterwards through "House Tools".
