A tutorial on using ordinary noodle commands in rhinoceros modeling
I. Monorail scanning
Sweep 1 Sweep along a path to create a surface by several section curves that define the shape of the surface.
There are several shapes in the monorail scanning options:
1. Free Distortion: The surface will be distorted with the path curve when sweeping.
2. Towards the top (front/right): The angle between the section curve and the working plane of the top (front/right) view remains constant during the sweep.
Second, dual-track scanning.
Sweep2 sweeps along two paths to create a surface through several section curves that define the shape of the surface. The usage of Sweep2 is similar to Sweep 1, but the difference is that there is an additional trajectory, which can better define the form. Therefore, the use condition of double-track scanning is that there are at least three curves, two as tracks and one as section lines. Of course, whether it is Sweep 1 or Sweep2, the number of section lines is infinite.
Third, lofting
Loft is a surface created by several section lines. So after determining the shape of the surface you want, you must first draw the section line of the control surface. There are two kinds of "open curve" and "closed curve" in rhino. The curves selected in the lofting command must be all open or closed, and they cannot be mixed. The following two forms are for reference:
Closed curve and open curve
There are also many effects to choose from in the lofting options to achieve the desired effect.
Fourth, the mesh wire is used to make the surface.
When using the command to create a surface with a network line, the drawn curve must be in one direction and must cross the other direction, and the curves in the same direction cannot cross each other. The boundary line defines the shape of the surface, and the midline is the skeleton of the surface structure. At the same time, it can also be understood as lofting through lines in two directions, and the lines in each direction are trajectories and section lines.
V. rotational moulding/Rotation along the path
"rotational moulding" can be understood as the shape swept by the contour curve rotating at a certain angle around an axis, while "rotating along the path" is the shape of the contour line rotating around an axis along a specified path.
In the process of rotational moulding, we should pay attention to the difference between the "plastic" option "Yes or No" in the command prompt. If it is set to "No", it means that the surface is created by right circle rotation, and the created surface is rational, so sharp edges may appear when editing control points; When set to "Yes", it means that the rotation direction of the reconstructed rotational moulding is 3rd order, which is an unreasonable surface, so that when editing the control points, the control points can deform smoothly.
The following comprehensive use of these commands will take you to understand the comprehensive use of several commands and the modeling process of a kettle in the form of actual combat.
Step 1: Draw a curve.
First of all, draw the structural curve, and the curve adjustment will not be detailed here. Adjusting the curve takes patience and time.
Step 2: double-track surface formation
Step 3: lofting into a surface.
Step 4: Create a surface with a mesh line.
Step 5: rotational moulding.
