How does CAD calculate the area?

CAD Calculation Area

The method of calculating the area of CAD

Method One: If the graphic is regular, you can use the query area in the tool command shortcut key is AA.

Next in order to select points can be selected, after the return, in the status bar will appear area and perimeter, take a number of areas removed 6 decimal places, the perimeter minus 3 decimal places. In the appropriate add allowance can be.

Method Two: If the graphic is irregular, you can use the following methods:

The first step, with the boundary command will be calculated as a whole area, the shortcut key to the boundary is: BO, in the use of tools in the query Area Command shortcut keys are: AA; Select O, the object can be, take the number ibid.

Method Three: Use Area Command: enter;

Method Four: 

1. For simple graphics, such as rectangles, triangles.

Just execute the command: area (can be the command line input or click on the corresponding command icon), after the command prompt "Specify,first,corner,point,or,[object/add/subtract]:" Turn on the capture select either the rectangle or the triangle intersection and then return, AutoCAD automatically calculates the area, perimeter (Perimeter), and lists the results on the command line.

2. For simple graphics, such as a circle or other multi-line lines (polyline), spline Line (Spline) composed of two-dimensional closed graphics.

Execute command: area, after the command prompt "Specify,first,corner,point,or,[object/add/subtract]:" Select, Object option, it is prompted to select the graph to calculate, AutoCAD, will automatically calculate the size, Circumference.

3. For complex closed graphs composed of simple lines and arcs, the area command cannot be computed directly.

You must first use the region command to create a graphic for the area you want to compute as a field, and then execute the command: areas, after the command prompt "Specify,first,corner,point,or,[object/add/subtract": " Select the object option and, depending on the prompts, select the field graphic AutoCAD that you just created to automatically calculate the area and perimeter.

Method Five: Use, area, command;

1. Filling;

2. Convert to multi-semantic line merging.

3. Surface fields.

Reg Space, select the Chinese and foreign boxes, and then Li command, you can see the perimeter of the area.

First with the field, you have to measure the area into a field, and then a AA (area) command, and then choose O, you can!

If you use a closed geometry that is drawn with a continuous multi-line line, right-click the graphic and there is an area and perimeter in the feature.

Input command: Region, select the area you need to calculate the line (arc also can), forming a surface field, press CTRL1 can see the need to calculate the perimeter and area.

Calculation of CAD BLOCK:

1, the proposal installs an Ivy Vine auxiliary tool, is specially for the CAD, the plug-in.

After installation, restart the Cad,cad menu bar below will show the Ivy menu bar, which has a number of calculated blocks, you click on the block you want to calculate, he will be on the command line to display the number of all the Block class in the diagram.

There is a shortage of ivy aids, he can not circle the range of calculation, only the entire graph as a calculation range.

PS.CAD Update faster ivy I was used on the cad2004 can, but, cad2007, do not support. Notice the version when you next.

2, with a quick selection command, the command line will prompt a total of the number of selected tiles;

3, select tools, Quick Selection, in the dialog box to select a block reference (blocks), the following select the name, the following is equal to, and then hit their own to find the name of the block, determine the following command line has selected how many objects.
