How to improve the modeling efficiency of Rhino rhino rhino? Courses to improve the efficiency of rhinorhinorhino modeling

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.

Courses to improve the efficiency of rhinorhinorhino modeling

I. Option Settings

Let's talk slowly, maybe not deeply, but as comprehensively as possible.

The first thing to do when you first get in touch with rhino is of course template and option setting. There are too many things to pay attention to. Let's start with the panel order of an option setting, which is basically something you can learn immediately by yourself:

1. Unit: There is an article in the original factory devoted to the definition and setting of rhinoceros tolerance. Those who are interested can go and have a look. Let me briefly talk about the key points here.

Tolerance is essentially accuracy. What we need to pay attention to is that nothing is 100% accurate, only tolerance. The concept of absolute tolerance in rhino can be understood as that the distance between two objects can be regarded as close enough to be combined or scanned, and colleagues are also the shortest length that can be drawn under the current document. Different modeling objects must have different tolerance requirements. In our architecture, the errors are all centimeters. There is a question on Zhihu, what is the allowable error of architecture? You can search if you are interested. We usually set it to 0.0 1, and the angular tolerance determines how much angular tolerance between two curves or surfaces of rhino can be considered as tangents. At present, if it is set to 1, when the tangent angle is less than 1 degree, it is regarded as tangent. Obviously, it's better to set it smaller.

In addition, in many cases, we will break lines in make2d, and even straight lines may break lines. At this time, the absolute tolerance can be adjusted very little. As for the display accuracy, it is the number of digits after the decimal point, which can be adjusted as needed.

2. Grid: It is the background grid that you can see as soon as you open it. It is customary to set the grid line as 1m, and the main grid line as ten sub-grids, that is, 10m, so it is easy to see the approximate proportional relationship according to the grid. So if possible, the model should be built in the window grid.

Many novices of rhino modeling, especially when importing cad, like to start modeling directly at the place where cad is imported, but the place where cad is imported is often infinitely far from the origin of rhino, and the grid lines are completely invisible. Note that this is not only a matter of habit, but also a matter of convenience to see the scale with the grid. Sometimes, the gap between the model scale and the template is too large, which will lead to bugs, such as broken display, such as importing revit to report errors and other inexplicable problems. Therefore, it is suggested to build a mm-level model corresponding to the selected template scale within the grid line, and vice versa.

In addition, the shortcut key F7 can control the display and hiding of the current view grid.

3. Grid: an option only related to the display mode. Don't worry if you find that your surface is broken. It may be that the display accuracy here is too low, so you can try it again by raising it, but it doesn't necessarily mean that there is no broken surface when it is adjusted to the highest level. At this time, you can choose to combine it into an entity, and the broken face is basically gone. In fact, rhino is a natural nurbs, but what you see in the window is actually a mesh transformed from nurbs, which is also the reason for the face breaking.

4. Note: dimensioning; Section line; lineshape

Why are rhinos useful? Because it is a two-dimensional and three-dimensional collaboration software, two-dimensional drawing is better than cad (not including Tianzheng), and three-dimensional modeling is accurate and fast (pay attention to this word). Then the three options under this option control our two-dimensional drawing. Actually, it's all very simple Everyone knows what cad is after using it for so many years, so just say a few words.

In the setting of dimensioning and cad gray image, the spatial scaling ratio is often set to control the display ratio of the same dimensioning style under different templates.

Although there are not many types of section lines, they are basically enough. If it is not enough, you can import cad patterns. Detailed operation methods can be found in our previous posts: Rhino draws various postures of section ~ ~ (key words RH 13).

There is nothing to say about linetype. Pay attention to a scale, or you may not see linetype at all. In particular, there is no concept of line width in rhino. Although this is very common and beautiful in cad, I always think it is something that destroys the accuracy of cad. It is natural that such a wide thread is covered there to catch the wrong one. Moreover, many times, so many lines will be repeated together. If you have different line widths, who knows how many mistakes there are.

5. Alias: used to set command shortcuts. You can choose to import the shortcut settings txt file of cad directly, and the shortcut commands of commands in rhino will be consistent with cad, such as pl is a broken line, E is deletion, and so on. Of course, you can also set it yourself, just depending on your personal hobbies.

6. material library: many people don't know that rhino has a material library. You can save the material in a folder, call it directly next time and drag it to the surface of the object, which is very convenient.

Right-click to save to a file and you can save the material you set ~

Let's briefly demonstrate it ~

7. Toolbar: used to save the settings of the operation panel. I suggest you back up one of your own. Many rhino users will have an experience that when rhino crashes, they will find that the interface is completely gone, leaving only a command input box. At this time, they can recover by opening their own backup rui file, and the middle mouse button settings will also be saved here.

8. Four auxiliary parts of modeling: transition setting, intelligent trajectory, cursor prompt and operation axis.

Press setting: used for fine adjustment, similar to ps and ai.

Wisdom track: the same as cad. It's very simple to use. I am used to all the functions. It can be generated automatically after the mouse is placed on the capture point for 300 milliseconds. It is very convenient to find straight lines and parallel lines vertically and orthogonally.

Cursor prompt tool: it is very convenient to display the relevant information of the current operation command in real time, such as distance, position, angle, command introduction, etc. However, my computer is toxic and will get stuck when modeling is turned on ... so I usually have no choice but to turn it off.

Operating shaft: something that can be used at a glance, pay attention to a few points. First, remember to check the view to rotate around the operation axis, so that the camera will automatically focus on the object you choose, which is convenient for adjusting the window; The other is whether you can choose a point to adjust whether you can capture the operation axis when moving, and check it as needed.

If the view rotates around the operation axis is not checked, this command may be used frequently.

There is also the location and size of the translation icon, which is the commodity. The reason why I mention this alone is because I have encountered a bug before and the translation icon has disappeared, so I will tell you alone that if this thing disappears, I will come and set it here, although I don't think many people will encounter this problem.

In addition, many small partners may not notice that there is a white dot in the center of the operating shaft. Clicking on it will pop up a dialog box, and the commands in it will not be explained much. You will know after reading it.

Add an object lock. Many times, when the model is large and there are many things, object locks and intelligent trajectories begin to be lost, which easily interferes with our modeling. At this point, pressing alt key during modeling can be used to close and open object locks and smart tracks during command execution. In addition, the alt key has another function. When you frame an object, you will find that the object is directly dragged away by your mouse, and the box selection is unsuccessful. At this point, hold down the alt key to directly frame and ignore all the objects in the window.

9. Keyboard: Set keyboard shortcuts.

The F7 on-off grid display mentioned above is one of them. Common examples are: F 1: Help F3: Attribute F6 Turn the camera F8 orthogonal F9 lock on and off.

Here, let's talk about the setting of F6 camera, because a friend asked the rhinoceros how to adjust the viewing angle of Su Like. It's a pity that rhino doesn't have relevant orders, but it's not impossible to adjust, and it's simple. You just need to open the camera through F6, wake it up and adjust it in several other views, or directly activate the current window, and then modify the location of the camera memory target point in the properties.

10. View setting: A good display mode can greatly affect the mood of the day. After all, not everyone wants to face a gray interface all day.

For detailed adjustment, please move: Su? No, its rhinoceros (keyword RH 1 1)

Note that the above picture is the name of an egg ... and put an adjusted display mode effect picture by the way.

However, there are many display modes of rhino, and flexible use of multiple display modes can also improve efficiency.

Render shadow mode to see materials and shadows.

You can print a line drawing mode to print a wireframe.

The inspection mode observes the front and back of the surface and the uv direction.

By the way, introduce a command: set the display properties of an object so that the object can adopt other display modes in the current display mode. For example, as shown below, they all adopt different display modes, but it should be noted that in the current display mode, objects will still be affected by the scene lighting settings.

So just adjust the display mode according to your own preferences ~ ~

1 1. Mouse: Set the function of middle mouse button. Personally, I like rhino's middle mouse button command, which is faster to use than typing the command directly. Of course, if you are used to su, you can also set the middle mouse button to view it.

But at least I don't recommend it. Using the right mouse button to rotate the window is much more labor-saving than using the middle mouse button, especially the middle mouse button I bought in the past is so hard that my hands are useless in the afternoon. Pay attention to yourself. The pop-up menu here is stored in the toolbar.

My middle mouse button setting is for reference only. Note that the order of my middle buttons depends entirely on the order of my commands, so there are no rules. It is recommended to set it according to your own preferences.

Put an M-sized middle key as a positive teaching material (picture from modern rhinoceros,)

Some people may notice that there are some commands that rhino doesn't have at all. These are all made up by m, and rhino's orders are still very intelligent. You can combine commands yourself to generate new commands. Even write code ... The following is a case of python code written as a command, copied directly from abroad, so rhino is actually very powerful, and this is just one of them. Never think that you have learned enough, and you never know more than you know.

12: Appearance: There is nothing to say about this, that is, a person who is used to using crosshairs in cad may like it very much, but it should be noted that rhino's crosshairs only appear when drawing and are not available when drawing.

There are color settings, the default grid color is too gray to like, I like to change colors.

13. File: used to set the template directory. The so-called default value refers to the template used by rhino to be opened by default. There is nothing to say about automatic saving, but I usually don't set it. Of course not recommended. I often build the model above a G, and every time I save it automatically, it will be stuck for more than ten seconds, which affects the rhythm. Yes, I have a good habit of control. I usually don't check the files of 3 DMBAK, because as I said before, I model. Another backup, another G or two are too big, so I will give it ... or because I have a good habit of ctrls ... otherwise, please check it honestly.

14. Idle processing: This is basically useless, but it is quite interesting. It is used to execute the save command when there is no operation for more than a specified time. The picture I can think of is ..........................................................................................................................................................................

15: General: You can set the command to be executed every time rhino is started, such as the following: gh is turned on every time rhino is turned on. Commands that never repeat are also easy to understand. Avoid some misoperation, such as accidentally pressing the space bar after rendering. ..........................................................................................................................................................

Two. floor

The next thing I want to talk about is layers. Don't worry, we won't break into the relevant parts of modeling until all the settings are completed.

Layer: rhino itself is a software with half cad and half cam interface. The interface with cad is very easy to use, which also determines its accuracy. But rhino is obviously superior in layer management, and its core lies in the selection of sub-layers and layers. Take an American model at work as an example.

Give me another comparison.

I can see that it is almost the same, but you may not feel anything just by looking at this. However, the arrangement of levels and the sense of hierarchy of objects reflect a person's habits. Different from Su's component group management function (Su's layer is a joke), rhino's model management is basically based on layers, supplemented by groups (rhino's group is only a concept of selection set, so you can use tiles to do this. In fact, if su imports rhino, the components are also directly identified as tiles), so the key point is to ensure the correctness of the object layer at any time. Once the fault is found, the first time. The ultimate goal is to realize the full classification of buildings, so that you can manage the model most quickly, choose what you want anytime and anywhere, and hide what you don't need. Here are the commands related to layers, such as closing other layers, opening only one layer, matching layers, changing layers and so on. Just come and find it if you need it.

In fact, the habit of layer management is easier said than done, but just like CTRL+S, everyone knows that it is a good habit to save it casually, and only regret it a moment before the software crashes. Therefore, I still hope that everyone can develop good habits. Once such a habit is formed, it will only be beneficial, not harmful.
