How to use CAD to enter coordinates to determine the position of a point

There are two ways to determine a point, one is through the line (polyline can also be used) command; One is the point command.

Straight line command: 1. Enter the "line" command enter in CAD (or click the straight line button in the drawing), enter the coordinates of the point that need to be determined (the n, e of the geodetic coordinates are just the opposite of x, y in CAD, n is the north direction, E is the east direction, and X is the right direction in CAD, and Y is the upper direction), in the input process, N and E coordinates are separated by half width, ", and enter after completion.

2. Click the left mouse button anywhere in the CAD drawing interface except for the points that have been drawn, so as to form a line segment. The first point of the segment is the location of the desired point.

Point command: 1. Enter the "point" command enter in the CAD (or click the point button in the drawing tool), enter the coordinates of the point to be determined, and then press Enter.

2. If the drawn point display is too small to be recognized, you can enter the "ddptype" command to adjust the point style until it is suitable for recognition.

For blank drawings, both of the above methods are applicable. For existing complex graphics, the straight line command is more intuitive and convenient. For locating multiple points, the Point command is superior to the Line command (the Line command can cause too many line segments to confuse each other).

Of course, it would be more convenient to determine the location of multiple points with the polyline command or southern cass.

CAD learns the coordinate input method.

You can locate the coordinate point directly with the mouse, but it is not very precise: you can locate the coordinate point more precisely by entering the coordinate value with the keyboard.

In CAD drawings, methods such as absolute coordinates and relative coordinates of the planar Cartesian coordinate system, absolute polar coordinates and relative polar coordinates of the plane polar coordinate system are often used to determine the position of the point.

Absolute Cartesian coordinates.

Absolute coordinates locate all points based on the origin. Enter the (x,y,z) coordinates of the point, z=0 can be omitted in 2D graphics. For example, the user can enter "10,20" (separated by a comma) in the command line to define the position of the point on the xy plane.

Relative Cartesian coordinates.

Relative coordinates are the position of a point (a) relative to another specific point (b), relative coordinates are the reference point of the previous input point as the input coordinate value, the coordinate value of the input point is determined by the previous point as the reference, and their displacement increments are x, y, z. Its format is: @x, y, z, "@字符表示输入一个相对坐标值.

For example, "@10,20" means that the point moves 10 in the x direction and 20 in the y direction relative to the current point.

Absolute polar coordinates.

Polar coordinates are defined by the distance and angle relative to the pole in the format: distance angle. The angle is measured in the positive direction of the x-axis, positive counterclockwise, and negative clockwise.

The absolute polar coordinates take the origin as the pole. If you enter 10<20, it indicates a point that is 10 degrees away from the origin and 20 degrees in the direction.

Relative polar coordinates.

The relative polar coordinates are the above operating point as the pole, and its format is: @距离 angle. If you enter "@10<20", the distance between the point and the previous point is 10, and the line connecting the previous point is 20 degrees to the x-axis.

Example: Instead of using only one coordinate mode throughout the drawing process, you can mix one, two, or three coordinate modes together. In Figure 2-30, we start with absolute coordinates, then change to polar coordinates, and then change to relative coordinates.

As a CAD operator, you should choose the most efficient coordinate method to draw.

Command: line

Start of the line:

Press Enter to exit the command).

The specific steps for CAD to enter the coordinate fixed point are as follows:

1. First of all, open the required CAD drawings and enter the page.

2. Then click on the command input bar at the bottom, enter "line", and press enter to confirm.

3. Then in the command bar, enter the letter l in turn, and then enter the coordinates in turn, 0, 0; 700,0；700,500；-700, 500, and then press the letter c (close command), and the rectangle is drawn.

1. Open the CAD software on the computer.

2. After opening the CAD software, click on the straight line option in the left toolbar.

3. After clicking on the straight line option, press the shortcut key.

Shift+2 to bring up the @ symbol.

4. After calling up the @ symbol, enter the x coordinate 200 first, click ", "Notice" to detect the hail collapse, and then enter the y-axis coordinate 300.

5. Enter the coordinate axis.

After that, press the empty and lose circle key, and the coordinate point will be found.

1. Open the CAD software on the computer.

2. After opening the CAD software, click on the straight line option in the left toolbar.

3. After clicking on the straight line option, press the shortcut key.

Shift+2 to bring up the @ symbol.

4. After calling up the @ symbol, enter the x coordinate 200 first, click ", "Notice" to detect the hail collapse, and then enter the y-axis coordinate 300.

5. Enter the coordinate axis.

After that, press the empty and lose circle key, and the coordinate point will be found.

1. First of all, open the project drawings of a project on the computer.

2. (x,y) in the drawing = (y,x) in cad When entering coordinates in CAD, the Y coordinates in the drawings should be entered first, and then the X coordinates.

3. Then click "Label" in the menu in the upper left corner and select "Coordinates".

4. Enter the coordinate values in the order of (y, x) in the input field, separated by commas. Imitation.

5. After the input is completed, press the Enter key to lock.

6. After finding the coordinates, we can label and record.

1. Open the AutoCAD2007 version of the soft macro cavity part on the computer.

2. After the computer opens the CAD, draw a figure first.

3. After drawing the graphic cover, enter the coordinate command id in the command bar, and then press the spacebar to confirm the command.

4. After entering the command, click on a point to get the data of the xyz axis of this point.

Operating Equipment: Dell Computer.

Operating system: win10

Operating software: CAD2017

1. First of all, you need to open the CAD software and enter the CAD operation interface.

2. After opening CAD, we find the polygon option in the tool area.

3. Select the polygon option to draw a pentagon in the drawing area.

4. After drawing the pentagon, we find the calculator option in the shortcut area above.

5. Click on the calculator option and find the Get Coordinates option in the pop-up dialog box.

6. Click on the Get Coordinates option, and we will be prompted to specify the point in the drawing area.

7. Select the point on the pentagon, and then you can determine the coordinates of the point in the computer dialog box.

1. First of all, we will open the CAD in the computer.

2. Enter the user interface, click the file option, select the "Open" button in the drop-down bar of the file, and open the required CAD drawing in the pop-up interface.

3. In the "Instrument" option in the upper function bar, click to select "Search Point" to find the given coordinate point in the drawing and display it in the window.

4. A dialog box will pop up in the interface, in the pop-up "Display Point" dialog box, enter data at the position of each axis, and click the "Display" button to find the coordinate position.

Draw in CAD.

We often use coordinates to find the location of a certain point, so how do we enter coordinates to find it? Let me tell you more about it.

How to enter coordinates to find points in CAD:2Then in the command bar, directly enter "400<30" and click "Enter". where 400 represents the length of the line segment and 30 represents the horizontal angle of the line segment.

3. How to make a relative polar coordinate.

Of course, why does it look incongruous here, because the absolute coordinate is relative to the coordinate origin, and he uses the coordinate origin as the reference point.
