This article mainly introduces the CAD in the measurement of graphics or a certain area of the shortcut key is what, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian with you to understand.

Cad area shortcut key is AA, but this method of measurement is not suitable for any situation; close the area to be measured, command boundary, shortcut key BO; select the boundary command as a whole, you can see the area.

The shortcut key to measure the area of a graph or an area in CAD is AA, but this method of measurement is not suitable for any situation.

The conventional method of calculating area is as follows

Command line, keyboard shortcut L, close the area to be measured, command boundary, shortcut key BO. Pick points to select the area to be measured, the selected area will be a whole, command list, shortcut key LI, select the boundary command as a whole, you can see the area.

Extended data

Area CAD algorithm for different types of graphics

① for simple graphics made up of straight line segments, such as rectangles and triangles drawn with straight lines.

Just execute the command area interpolation area (aa) command (can be entered on the command line or click the corresponding command icon), after the command prompt appears, select the intersection points of the rectangle or triangle in turn and enter, CAD will automatically calculate the final area (Area) and perimeter (Perimeter), and list the results on the command line.

② for a single Polyline, spline shape, such as circle, rectangle or other polylines (Polyline), spline (Spline) composed of two-dimensional closed shape.

After executing the area query command, enter the O (object) option according to the prompts, enter, select the drawing to be calculated according to the prompts, and CAD will automatically calculate the area and perimeter. For polylines, you can usually see the length and area in the property box (Ctrl+1).

Thank you for reading this article carefully. I hope the article "what is the shortcut key to measure the area of a graph or a certain area in CAD" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
