Rhinoceros Basic Course

In this block you will master the use of tools – NURBS curves.
Curves are the basis of surface modeling. We will build 2 logos, learn the tools for creating closed curves. Next, we use the curves to build a three-dimensional part by extruding closed areas.
At the end of the topic you will find interesting tasks that will complement your knowledge of curves as the basis for surfaces.

In this block, we will review with you the basic tools for creating surfaces.
Let’s divide this material into 2 groups: NURBS surfaces and SubDivide – a new set of tools for creating organic, amorphous 3D objects.
Surface creation tools – 5 commands that will give you the freedom of modeling. After creating surfaces, they need to be connected to each other using the interface and analysis tools – Zebra. After studying the video from this block, you will move to a new level of knowledge of the program. We will continue our acquaintance with SubDivide tools in the next topic.
The task will delight you with examples using Grasshopper parametric algorithms and teach you how to use UV to transfer texture from a plane to a curved surface.

At this stage, we will study the transformation tools.
We place elements on the wheel to create a texture, and use different methods of transferring elements for subtraction from a plane to a rolled surface. In another example, we arrange an array of elements along the curve and along the curve on the surface, when editing the curve, the elements also change, work with history is performed.
In the task, the continuation of topic 5 is the construction of an object twisted in a spiral. A twist, a twisted object, is used in forged products to obtain filigree braids. We are considering a method of obtaining a twisted object from a flat one and moving it along a folded curve, using the Twist, FlowOnSurface, FlowOnCurve tools. After that, it is necessary to analyze the length of both curves.
The additional task considers the command of stretching an object over a surface with the possibility of repeating the object using the example of a Japanese ornament.
