What are the applications of UCS coordinates in CAD?

UCS is the coordinate system for CAD. The floor plan is drawn with very few modifications. In fact, we use it all the time.

It may be used, for example, the plane positioning map in the building, sometimes in order to make the site look good, the map will be "rotated" to a certain extent, that is, UCS will be used for user-defined coordinate system, which has the advantage of not destroying the coordinates of the original positioning map, if you want to intercept the correct coordinates, you only need to change the coordinates back to the world coordinate system. If you use the rotate command, it's easy to get the coordinates wrong.

The UCS command is the order of the coordinates, and there are xyz 3 directions and 6 faces in 3D, and we need to constantly switch coordinates to determine the direction and the plane in order to model accurately. In the plane, we only draw on one plane, only in xy two directions, then there is no need for 3D coordinates, and there is no need to switch faces. Basically, there is no need to consider the factors of space coordinates, and UCS is rarely used.

However, we sometimes use it for plane positioning, that is, to determine the position of the origin coordinates. It's just that the usage at this time shouldn't be the UCS you said.

UCS is sometimes used for coordinate annotation. For example, when you draw a rectangle with some holes in it, you need to mark their positions. Linear annotations are fine, but sometimes they are not ideal, so coordinate annotations are required.

Enter "UCS" - enter "M" (move) - select the center of the rectangle as the new UCS origin, then the center point of that rectangle is 0,0 (of course, this is relative coordinates, absolute coordinates are unchangeable).

Click "Coordinate Labeling" on the Annotation toolbar - select the coordinates you want to annotate - select the location where the annotation text will be placed - and then you can use continuous annotations to label those coordinates that need to be annotated. Give it a try.

UCS is a command that is often used in CAD drawing. Common uses include setting the user coordinate system and switching the world coordinate system. Let's first explain the meaning of the two coordinate systems.

The world coordinate system is the coordinate system that comes with CAD software, which has its own origin and vector, which is something that cannot be modified by the user. What the user can modify is the user's coordinate system.

In the case of the user-defined coordinate system, when the drawing is in the world coordinate system and the baseline is tilted, it is more troublesome to use CAD drawing, orthogonal and other commands, so it is necessary to set the UCS user coordinate system. Make the position and orientation of the drawing conform to your own usage habits and the requirements of drawing efficiency.

The way to customize the coordinate system is to enter the usc command on the command line of the CAD. Then follow the operation to define the coordinate origin first, then the x-axis, and then the y-axis.

There are several common items in the ucs command, which are to set the current ucs, the previous ucs, and the world coordinate system. Each coordinate system is independent of each other and does not interfere with each other.

When you use TENGEN CAD, sometimes you will find that your text and annotations are missing, and your coordinate system looks normal, at this time you may be in a 3D view. When the plane is switched in 3D, the text and annotations are displayed. To do this, enter the plan command and select the w command.

When you need to return to the 3D view, all you have to do is click on UCS and use the view command. The way to convert a plane to 3D is to hold down Ctrl+Middle Mouse Button and then rotate the mouse to render a 3D image back.

CAD 3D image for plane homing. In this case, both the ucs and plan commands can be used. The way to use UCS plane homing is to enter UCS and select the W command.

Its principle is to return to the world coordinate system. To use the plan command, type plan and select the w command. It works by returning to the plane of the world coordinate system.

The two have the same end, and the effect has always been. You can choose which command to use.

I believe that friends who are more familiar with CAD know that UCS is the abbreviation of User Coordinate System. In general, the coordinate system commonly used for drawing in CAD is the World Coordinate System (WCS). However, in some special cases, because it is troublesome to use the world coordinate system to establish a coordinate system drawing, you need to set a new reference coordinate system according to your actual needs, which is the user coordinate system.

There are three main applications for UCS:

2) Adjust the direction of the coordinates so that you can draw oblique drawings.

Usage: Enter ucs on the command line - press enter - enter z - enter the angle that needs to be rotated.

3) Position the coordinate system to a surface of the model as needed for modeling.

Usage: Enter ucs on the command line - press enter - enter f - select one side of the model.

1. This is a cube with an inclined surface and the other faces perpendicular to each other. You can see that the world coordinates are displayed in 3D space. This is not going to change in space.

2. Under normal circumstances, any line drawn at will be drawn on the xy plane of the world coordinates.

3. Before defining the UCS coordinates, you can actually draw geometric lines on different planes. As long as you move the mouse over the corresponding face, the face is activated, and you can draw freely on that face.

4. The graph will be read with the newly established UCS coordinates as the origin. Without UCS, all data is generated from world coordinates.

5. After entering the "UCS" space first, it is the beginning of the creation of UCS coordinates.

6. The default UCS coordinate creation is to determine the origin of the coordinates, the direction of the x-axis, and the point on the xy plane; If these three conditions are met, a UCS coordinate is generated.

7. If the creation method is selected as Face (F) or Object (OB).

8. Select the previous one, and the generated UCS coordinates are the UCS coordinates of the last built.

9. The three axes of the last XYZ can be selected separately, and its function is to rotate the corresponding axis at the position of the world coordinates to generate new UCS coordinates.

10. If you want to return to the world coordinates, enter UCS and enter w to return to the world coordinates.

The following are examples of how to use UCS in CAD and how to operate it:

1. This is a cube with an inclined surface on its top surface and the other surfaces perpendicular to each other. You can see that the world coordinates are displayed in 3D space, and the space does not change, as shown in the figure below.

2. Usually, draw a free-form line on the xy plane of the world coordinates, as shown in the figure below.

3. Before defining the UCS coordinates, it is actually possible to draw geometric lines on different faces. As long as you move the mouse over the corresponding face, the face will be activated, and you can draw freely on the face as shown in the image below.

4. The graph will use the newly established UCS coordinates as the origin reading. If there is no UCS, all data will be generated with world coordinates as the origin, as shown in the figure below.

5. After entering the "UCS" space, start creating UCS coordinates as shown in the figure below.

6. The default UCS coordinate creation is to determine the origin of the coordinates, the direction of the x-axis and the points on the xy plane. Satisfying these three conditions can generate UCS coordinates, as shown in the image below.

7. The selected creation method is surface (f) or object (ob), as shown in the following figure.

8. Select the previous one, and the generated UCS coordinates are the UCS coordinates of the last version, as shown in the figure below.

9. The last three axes XYZ can be selected separately, and the function is to rotate the corresponding axes at the position of the world coordinates to generate new UCS coordinates, as shown in the figure below.

10. If you want to return the world coordinates, please enter UCS and then W to return the world coordinates as below screenshot shown.

How to use UCS to create new limbs as coordinates in CAD? In fact, it is very easy, let me tell you how to use UCS to create new coordinates in CAD, let's learn together.

How to create new coordinates with UCS in CAD:As a simple example, let's say I drew a picture like this.

Start with shortcuts.

UCS – Spacebar, <>

Then choose according to the following prompts, you can choose ob (of course, you can also choose others, this according to your needs) - spacebar, and then select the direction you need to change, such as as in the figure below, the town changes and selects a direction with the line segment 1, then you can select this line, and then what you see is that the coordinates are consistent with the direction of 1. Travel balance.

1. First of all, in the layout, we create two layout boxes, and then we can compare them. First, we can see that the current coordinates are consistent in both layouts.

2. We are now in the layout, use ucs - W - Space - Space - Pull a line in the direction that needs to be changed (as shown in the line segment) - Space.

3. After comparison, you can see that the coordinates in the two layouts are different. The effect is as follows.

It is useful to use shortcuts as much as possible to find some CAD drawing skills. Review the original post

First of all, mechanical drawing must be learned, and then the spatial imagination ability should be good, find a good textbook, learn the knowledge in the book thoroughly, and think more about how to complete the operation.

Work hard to achieve natural success.

Look at the video tutorial, take a set of drawings, copy and draw again, it's basically almost, it's better to have someone to guide it, the focus of each major is different, like I do structural design, it's a little simpler, mechanical design, clothing design, they use more complicated.

1. Browse a textbook. It's browsing, not perusal.

2. Find a ** and make it as it is. It must have been found, not wanted; Be sure to do it the same way, don't go out of shape.

3. Find a bunch of information and do addition, subtraction, multiplication and division.

5. Find a way to make some operations complete.

6. Find a way to let VBA complete some processes.

When you can't do it, first look at excel to help you rent and help, and then search for it, for example, the keyword is: excel page break.

Study 4 hours a day, and you will be able to cope with 90% of the tasks in half a month.

It depends on whether it is self-study or to a professional training institution to learn, if there is a clothing pattern making foundation, self-study can also be, of course, good teaching materials are indispensable, the best is video teaching materials, 58cad has a lot of information in this regard, I hope to help you.

Sign up for the training class, and find a company to make a drawing. CAD has no shortcuts, can only be used more, remember more command abbreviations, read more drawings, and be proficient.

AutoCAD software to learn the basic operation, draw two-dimensional drawings, someone to guide one to two hours a day, more than ten hours can be, and then immediately their own actual repeated operation, familiar with more than ten days, you can draw simple drawings, repeated repetition can be familiar with the brigade type tomb, theory and practice combined, mainly tool commands and other operations, books are available, skills in practice groping, the basis of three-dimensional drawing is two-dimensional drawing, I am a mechanical engineer, I wrote the "zero-based learning AutoCAD" Suitable for beginners.

1.First of all, you must have the habit of thinking in English, which is more complex than verb conjugation, and the rules of these conjugations are subject to personal pronouns, tenses, and voices. You won't get it wrong when you think about these basic grammars when you speak.

3.Watch a little bit every day, don't be too expensive to insist. If you have mastered a vocabulary of about 1,000, you can basically go on the road. As for whether you can write a good article or make a difference, it depends on talent and opportunity.

Steps:

1. Open the AutoCAD software;

2. Enter the usc command on the command line and press the spacebar.

3. Select the object you want to transform and press the spacebar;

4. Select the direction you need to change to change the direction of the coordinate system.

UCS changes the coordinate system. For example, let's say you draw a circle, and the circle can only be drawn on the xy surface. If you want to draw on the xz plane, you'll have to change the coordinate system. Method: UCS rotates 90° about the x-axis

ucs is a 3D coordinate conversion command that can be adjusted to the angle you need.
