I. OBJECTIVE:

This parametric wall is one of the examples from the Forest Cabin Bundle, which presents different ways to non-destructively generate parametric walls in Blender. No programming knowledge is required to use the walls.

II. ABOUT:

This example can serve as a template for generating similar walls. The basic geometry is defined ONLY by modifiers. Control of the shape is defined by manipulating the vertices. The easiest way how to achieve complex shapes is to use of Proportional Editing Tool. Thanks to this setup, a large number of other variants can be obtained.

III. WHAT YOU WILL LEARN?

By understanding the principles used in this single model, you can create your own designed walls in Blender.
