How is the length, width and height calculated in CAD

Method 1] The method is as follows:

After selecting all of them, right-click and the property bar will appear, in which the geometry has the length, which is the sum of the lengths.

Method 2] Enter the command: li, which is the shortcut key of list, which also has area, length, etc., you can try.

You need to enter the command first, select the polyline, and then confirm, and a text window will appear, which has a clear introduction.

I can only calculate the area, but I don't know how to calculate the length separately" How is the area calculated? Indissoluble! In CAD, the default unit is "mm", but there may be proportions when drawing, so be careful.

When drawing at a scale of "1:1" (generally 1:1 drawing), click the "Distance" command (the icon of a ruler) in the toolbar, or click the "Distance" command in the tool menu, then click on one end of the line segment you want to measure, and then click on the other end, you can read the distance value (in millimeters), and then convert it to the desired unit (such as meters), and you will get the result.

If the area is measured, then click the "Area" tool, and then take the points on the boundary line of the graph to be measured one by one (generally the endpoint, the turning point, etc., if it is a curve, you can take any point on the curve, as many points as possible), and the last point is to take the first point of the first point, forming a closed curve that connects end to end, OK, you can read the area value, pay attention to the unit. Measuring length and area in CAD is easier and more correct than calculating.

How to calculate the total length of CAD:

First of all, search on the **"CAD calculation total length plug-in", I was before**good, it was in the cloud sharing of other people's web pages**, **after the plug-in is shown in the figure, here I will not repeat the search, you can try it**.

Then go back to the CAD drawing for which we want to measure the length and click "Tools" - "Load Application".

The command bar at the bottom will prompt "Loaded successfully", and we can click "Close" to close the dialog box in the interface.

After we load successfully, we directly enter "zcd" (that is, the pinyin abbreviation of total length) in the command bar, and then press the "enter" key to confirm.

After selecting multiple segments, press the "Enter" key to confirm, and the total length of the multiple segments will appear on the command bar.

DI measures the distance. CAD units are millimeters.

You can also mark it first and then delete it.

DLI (horizontal and vertical annotation) and DAL (parallel annotation) are all available.

Frame the course with multiple lines Click on multiple lines Right-click on Features Geometry to see the area and perimeter Or click on multiple lines li or aa to select them one by one.

The unit of length is the same as the unit of area...

The length is not calculated, but it is measured. Shortcut key DI.

Annotation is not on the line.

CAD units are millimeters.

Taper representation: the ratio of the difference between the diameter of the two bottom circles and the height of the circle is 1:5, and the red dimension is.

2x:(62-38)=1:5
