To know the coordinates (Co-Ordinate) of a point (Point) on Shape 2D or Form 3D, use the command ID (Command:ID).
The steps for using the command are as follows:
For example, there is a 2D Rectangle shape as shown in the Figure 1.
If you want to know the coordinates of the lower left corner. Type the ID command into the command prompt as shown in the Figure 2.
After Enter to execute the command select the desired point. For accuracy use OSNAP (e.g., Endpoint). When you click to select a point, ACAD will display the X, Y, Z coordinates immediately as shown in Figure 3.
In the case of a 2D shape, the Z coordinate value = 0 because there is no height value.
If it is a 3D form, it will use the same command and ACAD will display the required X, Y, Z coordinates.
