Rhino is a good 3D modeling tool. Although it is only tens of megabytes in size, it does not require much hardware. But it contains all the NURBS modeling functions, which is the main reason why rhino is popular. Everyone likes to use it to make high-precision models for other 3D software. If you are also engaged in 3D design, you must learn to use Rhino software. Rhino not only has low requirements for computers, but also is very simple to use. You can learn to use it through self-study. The Basic Course of Rhino Industrial Design and Modeling is a very good self-study course, and many self-study rhinoceros friends are watching it. Rhino plug-in T spline uses three lines to complete 3D chair modeling.

Introduction of rhinoceros inserted t-spline;

TSplinesForRhino5 is a multifunctional polygon modeling plug-in, which can be used in rhinoceros 5.0 applications and is suitable for professional designers. The software has been widely used in jewelry design, toy design and other functions since it came out. The software is similar to nurbs on the whole, and can be used for local subdivision and merging of two Nurbs patches, which can greatly improve the efficiency and rendering performance of designers.

Three-dimensional chair model drawing

Step 1: Draw two lines like this to determine the most basic shape.

Step 2: use the command crv2view (this command is to find the intersection of two curves in space), and then you can hide these two black lines.

Step 3: Switch to the right view, draw the legs of the stool, and determine the plane of the seat and the shape of the back of the stool.

Step 4: switch to perspective mode to deepen modeling, say three, never do more, and complete wiring.

Step 5: The rhinoceros part is over, and I come to T-spline mode. I choose these two lines, and I connect them so that I can make a natural interface.

Click the icon below or enter tspipe.

The following appears.

Let's analyze the subdivision instruction under this tspipe command.

The first is the radius. The default radius is 1, which is a bit large. We changed it to 0.5, and found that the number of subdivisions increased after the change.

Then there is segmentation, that is, the number of boxes. Enter s to activate, zoom in to find those red dots, press enter first, and then enter the subdivision number. Both lines can be modified separately. (Not easy to find, usually in the middle of the line), we cut the fine score by half.

Step 6: Another way to modify the radius is to make a gradual change from big to small. After zooming in, you can see that there is a small blue circle on the edge of the curve, which is the radius. Click it and enter a number to modify the size. Here, I changed both ends of this line to 0.4, so the radius of this line is no longer 0.5.

Then enlarge the interface of the wire. In fact, you can modify the interface mode here. If you find that your interface mode is unnatural, you can modify it. (The pipeline can still be modified after confirmation. You just need to select this object, and then click T-pipe again. )

Step 7: After confirmation, it seems that this shape is wrong, because smoothmode has not been started.

Turn on this switch to start editing mode, select this object, and then click the tab on the keyboard to start smoothing mode. You get the shape below.

Step 8: Choose another curve in the same way, make a leg, and then finish it quickly.

Step 9: Make a mirror image.

Strengthen the mode of selecting faces in this column, and select these two faces to delete, because they are to be mirrored.

Please do some preparatory work before performing mirroring again.

Select an object to select this control point mode, and then enter setpt to align the leftmost eight points to ensure that they can be connected after mirroring.

Use this command, enter a twice in a row, then confirm (the first a is add in the specified subdivision command, and the second is axis symmetry), then find the center of an axis of symmetry, and click OK!

Get the following pictures

Step 10: Next, come to the trump card command, tsbridge, which can connect two faces to form a natural interface.

Select the place to be welded, as shown in the figure below, and enter tsbridge.

Then you will see these dots and arrows. The points where the arrow is located will be connected together, and the arrow indicates the order in which the four points are connected. If you don't want to distort them, make sure the arrows and points are in the right position.

After welding, the surface is obtained. Because the symmetry command was just used, another surface was automatically welded.

Next, make a chair back, using the same method, but because the distance is far here, enter tspline first and then S, and change the fine score to 4.

After all three are connected, you get these three. It doesn't look good. Nothing can be modified.

Select the edge line, pay attention to the setting of the sidebar, select egde mode and scale mode, and double-click the blue box to zoom.

After all three are modified, you get this, and then you can make a seat.

Step 1 1: Bridge after subdivision, select these ten faces and choose this command.

The surface has been refined, and then continue to bridge.
