Layers and Marks course review. Nicole is an excellent teacher who combines clear descriptions, lessons in bite-sized chunks, and an enthusiasm for learning.

ND (Non-Destructive) is a Blender add-on designed to revolutionize 3D modeling workflows by offering a range of tools and operations tailored for non-destructive modeling techniques. With ND, users can enjoy enhanced flexibility and efficiency in creating 3D models, particularly for hard-surface forms.  The key feature of ND is its emphasis on non-destructive editing, allowing users to adjust parameters and make changes to their models quickly without the need for manual poly-modeling. This approach is particularly beneficial for iterative design processes, as it enables artists to experiment with different variations and refine their models with ease.  One of the primary methods employed by ND is the extensive use of modifiers, which play a central role in enabling a flexible modeling workflow. These modifiers allow users to apply various transformations and effects to their models without permanently altering the underlying geometry. This means that changes can be made at any point in the modeling process, providing greater creative freedom and control.  Overall, ND offers a comprehensive toolkit for non-destructive 3D modeling in Blender, empowering artists to streamline their workflows, iterate more efficiently, and achieve high-quality results with ease. Whether working on personal projects or professional productions, ND provides the tools needed to take modeling workflows to the next level.
