Finding the Relative Coordinate Conversion Absolute Coordinate Method in CAD! Satisfied with the add

Absolute coordinates. 1.Cartesian.

Cartesian coordinates are represented by the x, y, and z coordinate values of the point, and the coordinate values are separated by commas.

2.Polar coordinates.

Polar coordinates are used to represent two-dimensional points, and their expression is: distance "angle".

3.Spherical coordinates.

The spherical coordinate is used to determine the point in three-dimensional space, and it represents a point with three parameters, that is, the distance l between the point and the origin of the coordinate system; The angle between the projection of the origin of the coordinate system and the space point on the xy plane and the positive direction of the x-axis (referred to as the angle between the x-axis and the x-axis in the xy plane); The connection between the origin of the coordinate system and the space point is the angle between the xy plane (referred to as the angle between the xy plane) and the symbol "<", that is, "l< For example, 150<45<35 represents the spherical coordinates of a point, and the meaning of each parameter is shown in the following figure.

4.Cylindrical coordinates.

The cylindrical coordinate also describes a point by three parameters: that is, the distance between the projection of the point on the xy plane and the origin of the current coordinate system; The angle between the projection of the origin of the coordinate system and the line of the point on the xy plane and the positive direction of the x-axis; and the z-coordinate value of the point. The distance and angle are separated by the symbol "<", and the angle is separated by a comma from the z-coordinate value, i.e. "< z".

For example, 100<45,85 represents the cylindrical coordinates of a point, and the meaning of each parameter is shown in the figure below right.

5.Relative coordinates.

Relative coordinates are coordinates relative to the previous coordinate point. There are also four forms of relative coordinates: direct coordinates, polar coordinates, spherical coordinates, and cylindrical coordinates, and their input format is the same as absolute coordinates, but the input coordinates should be prefixed with the prefix "@".

Basically, there are only a few kinds of coordinates input in CAD, and everyone can learn it.

The UCS toolbar in CAD defines the coordinates of each point in the diagram, and you can set the X and Y axis directions by yourself.

Obviously, you don't know what relative coordinates are and what absolute coordinates are.

Absolute coordinates are based on the origin of coordinates (0,0) and extend to the periphery, distinguished by positive and negative.

Relative coordinates are to enter an @ symbol in front of the value of a point at the starting point.

For example: Rectangle: 100 long, 50 wide

The absolute coordinates are the first point (0,0), the second point (100,50) and the relative coordinates are the first point (0,0), the second point (@100,50) or draw the first point anywhere in the drawing area, and then enter the second point (@100,50) in the command line.

Understand it for yourself.

It is the measurement site and the rear view point, the Y coordinates and X coordinates in the CAD coordinates are just the opposite of the actual construction coordinates, I have the operation methods and steps of the total station here, see for yourself. Send your mailbox to see if you are satisfied, hehe, I am also a freshman who has just come out, I am doing the scene, for the measurement of this piece, we have our own surveying class, and when we want to measure, we give them coordinates to let them come and stake out by themselves.

In CAD, the method of converting coordinates depends on what type of coordinates you need to convert to another. Here are some common ways to convert coordinates:

Convert Absolute Coordinates to Relative Coordinates: In CAD, relative coordinates can be used to move or copy images more conveniently. To convert absolute coordinates to relative coordinates, first select the object and then enter it"move"command or use the Ctrl + Shift + M shortcut to open the move command.

Next, specify the base point and enter it"@0,0"to convert absolute coordinates to relative coordinates.

Convert Relative Coordinates to Absolute Coordinates: If you want to convert relative coordinates to absolute coordinates, you can use them"list"command to view the object's current coordinate value. Select the object and enter it"list"After the command, the details of the object, including its current coordinate value, are displayed on the command line.

You can use these values to calculate and enter new absolute coordinate values for objects.

Coordinate System Conversion: There may be times when you need to convert an object from one coordinate system to another. In CAD, it is available"ucs"command to change the coordinate system.

Select"ucs"After the command, you can select different coordinate systems, such as polar coordinates, Cartesian coordinates, and so on. After you select a new coordinate system, you can use the same relative or absolute coordinate command to modify the position of the object.

1. Hold the CAD, find the toolbar at the bottom of the CAD interface, and find the option "Dyn", as shown in the figure below.

2. Right-click "Dyn" and click "Set Divination" in the options bar, as shown in the figure below.

3. Find "Pointer Input" in the "Dynamic Input" of the sketch settings, and click on the Moqing setting below, as shown in the figure below.

4. Then convert the coordinate system you want to use, as shown in the figure below.

5. Click the OK button in the lower right corner, as shown in the figure below.

The specific steps are as follows:

1. First of all, open the TENGEN Architectural CAD, right-click the position shown in the figure, select [Settings], as shown in the figure below, and then enter the next step.

2. Secondly, in the pop-up window, select the Dynamic Input tab, click the [Settings] button below, as shown in the figure below, and then enter the next step.

3. Then, in the pop-up window, change the absolute coordinates to relative coordinates under the format as shown in the figure below, and then go to the next step.

4. Finally, the corresponding results are obtained, as shown in the figure below. In this way, the problem is solved.

At present, CAD drawing in various industries does not use a large number of coordinate input to draw drawings. Absolute coordinates: refers to the coordinate origin of 0 and 0 is always on the coordinate axis, and any input coordinate value is calculated with this point as the origin of the parameter.

Running for example, running 10 steps and 20 steps are only for the starting point to calculate the distance) relative coordinates: refers to the input.

First of all, it is necessary to determine the real scale of the CAD drawing, under normal circumstances, the scale used in the CAD drawing is 1:1, but when the drawing is limited by the size of the drawing, the drawing will be reduced to a certain degree of printing, such as: 5000, etc., this scale is called the drawing scale (or printing scale).

As mentioned above, a certain territory is required.
