Analysis of application examples of AutoCAD coordinate labeling

We often have this in the process of drawing: irregular hole distribution or similar entities (especially when more), if the use of conventional linear tagging, easy to appear cluttered, affecting the reading (as shown in Figure 1), the use of coordinate tagging method to maximize the solution to this problem.

In this paper, the application of coordinate annotation is illustrated with an example above. (from the cartographic point of view, you can also use "hole table" to indicate the location dimensions of each hole).

We usually have a linear, alignment, angle, and other types of dimensioning, but the coordinates and their use are different.

The basic principle of coordinate tagging

First, define a relative origin, this point relative coordinates (0,0), all other points to be labeled (such as the center of the hole), respectively, mark the points relative to the origin of the x,y distance.

In short, the following steps are essential for marking coordinates:

1. Customize the origin point of the callout.

2. Set the corresponding callout style (if you use the existing callout style, this step can be omitted).

3. Coordinate marking.

4. The corresponding reorganization adjustment.

For example, we follow the above steps to perform an instance operation.

1. Define the origin point of the callout

The origin itself can be flexibly defined, generally defined at the center point of the graph, the corner point, or some other datum points.

The order is as follows:

Enter at command line: UCS (carriage return)

COMMAND: Enter options: [New (N)/Move (M)/orthogonal (G)/prev (P)/restore (R)/Save (S)/delete (D)/Application (A)/?/World (W) < World]:

Input: M (carriage return) (note: input m, move to UCS coordinate system)

COMMAND: Specifies the new origin or [z-depth (z)] <0,0,0>:
