It's not free unfortunately, but blender won't take you where you need to go. Following the guide should enable you to become familiar with blender and Ti min ph ti liu Blender xna precision modelling.pdf, download, ti min ph. It uses a structured approach to introducing Blenders tools and work-methods. I'm a bas relief sculptor working mainly in zbrush and blender and I've cube across this issue when making embossings for wine bottles.įor your needs, I would advise looking at Rhino, which is basically blender for nurbs. Introduction This guide was created to assist Artists and Engineers, to learn the basics of mesh modelling of non deformable objects with Blender. It is possible to create a NURBs surface from a polygon mesh, but this involves turning every polygon into a separate NURB, which is very impractical. Companies manufacturing cans and bottles will probably ask you to provide IGES or STEP files of your models. *Blender can create nurbs, but the functionality is limited, and is geared towards turning the NURBS into a poly mesh. Polygon modelling is more akin to Photoshop/ jpeg.Įngineering/ manufacture leans towards NURBS because it guarantees accuracy at any level of detail.

If you're familiar with graphics in any way, then you can think of nurbs as vector drawing like Adobe Illustrator. Higher accuracy needs a higher number of polygons. Polygon uses a 'mesh' constructed of triangles or quads to create a surface. NURBS uses mathematical calculations to create surfaces, so they are incredibly accurate, and usually used for engineering purposes. In a nutshell, there are 2 types of digital modelling - NURBS and polygon.

If you're building things with a view to manufacture, then blender isn't the best choice.
