How does CAD define the thick line width, and why is the line width set in CAD, and why the line is

1. For us, CAD does not display line width by default, which means that when we use CAD drawing, the thickness of the drawn lines is the same. First, we click on Format above the toolbar.

2. Then select the line width in the drop-down box.

3. Then we select the line width and click OK, so that our line width will be modified.

4. But we will find that the width of the line we draw is the same, which is the CAD mentioned above does not display the line width by default. If we want to visualize the thickness of the line, we need to set the display line weight.

5. We still click on the format on the toolbar and select the line weight. Here we click on Show Row Width and then click on OK.

The operation steps to set the CAD line width in Haochen CAD:

First of all, open the drawing file in Haochen CAD software, and then select the CAD polyline that needs to be adjusted, and find and set its [line width] in the property bar on the left side (if the property bar on the left side of the software is not displayed, you can use the shortcut key: Ctrl+1 to call it out). As shown in the figure below:

In addition to setting the CAD polyline line width in the property bar, you can also call up the [Line Width Setting] dialog box through the [Format] - [Line Weight] in the menu bar, and click OK after setting the required line width in the dialog box. As shown in the figure below:

<> if the line width of the CAD polyline is not displayed after the line width setting is completed, you can click the [Show Hide Line Width] button in the status bar below Haochen CAD to turn on the line width display. As shown in the figure below:

After clicking the [Show Hide Lineweight] button, the CAD polyline lineweight can be displayed (if the lineweight is still not displayed after clicking the Show Lineweight button, you can run the RE command to regenerate the model). As shown in the figure below:

Multiple ways to set line widths! However, the purpose of setting the line width is not to call out two kinds, 1The line needs to be thickened during the drawing process.

a.For example, in the electrical profession, designers need to identify bridges, pipes, etc., will use some lines that look thick, the safest way is to use the "polyline" command "pl" to draw the line, double-click to pop up the characteristics dialog box, change the global width of the line width "10" is 10 mm. Of course, you can also set the width of the line on the command line after typing the pl command!

b.If you don't use a PL line. You can also set the lineweight as needed in the lineweight settings in Object Properties.

However, in order to be able to see the width display immediately, you need to press "Lineweight" in the "Status Tray" at the bottom of the software, but this method does not fully reflect the lineweight, for example, the lineweight with a value of 0 is displayed as a pixel width in model space. Selecting the display lineweight may increase the regeneration time. The most important thing is that the maximum width is only millimeters.

2.Print aIf you need to change the line width for printing, there are various ways to set it!

The above b method can also be satisfied, but it is generally customary to use color to associate line weights. Press "Ctrl+P" to pop up the print dialog box, select "Monochrome" in the plot style table to pop up the "Plot Styler", you can print the characteristics of the final color for each color, including "color, line shape, line weight" and so on. Of course, when the line width you can be 20 mm or even larger.

Don't forget to name and save the print style for later!

What happens if the line width is set in CAD, but the line is drawn or thin? How to modify the line width of a drawing in CAD? Below I have compiled some methods and steps, I hope it will be helpful to you. Method.

The reason why the line width is still thin after setting the line width is that the "line weight" display is not turned on, press "line weight" at the bottom of the CAD state, and you can do it.

How to set the line width in CAD:

Double-click the CAD icon to start the CAD, as shown in the figure below is the interface after the CAD is opened, here it is AutoCAD Classic by default. At this time, I found that the toolbar on the right, the yellow frame is the one that adjusts the line width.

Please click Enter a description.

Click on the inverted triangle icon to the right of the line width, you can choose the line width according to your needs, here is a rectangle as an example. Of course, it is okay to set the line width first and then select the shape, generally using the first selection of the shape and then changing the line weight. Select the rectangle first, and then select the line weight.

Please click Enter a description.

1. First of all, we open the CAD software in the computer, open a straight line, click on the line, and select the line.

2. The line will generally present the default color, and we can choose the color of the line.

3. Then select the width of the line.

<>5. Enter the line width setting page and click the Show line width button.

6. Close the hidden page of the line width, and you can see that the line has become wider on the CAD page, and the line width is displayed at this time.

There are many national standards, such as GB T 18229-2000 CAD Engineering Drawing Rules, GB T 50001-2010 Unified Standard for Housing Architectural Drawing, GB18135-2008 Electrical Engineering CAD Drawing Rules, as well as GB T50104 Architectural Drawing Standard, 50105 Building Structure Drawing Standard, 50106 Water Supply and Drainage Drawing Standard, GB T14665 Mechanical Engineering CAD Drawing Rules, etc. Roughly the width is grouped and divided into series values. The implementation of various design institutes, companies, and professions is not uniform.

We print out the base map (blueprint) of the large printer (880mm wide paper) is generally to take the following values (thick, medium, thick, medium and thin) (generally not related to the picture sheet): , in line with the national standard), among them, a large number of thin solid lines, dotted lines, dotted lines, etc., as well as words, main lines, thick trunk lines, do not need to be obvious or even thinner. However, the A3 or A4 printer for office use the above values is too coarse and too expensive, and it is not clear, so it is recommended to apply:,

In mechanical drawing, the thick line and thin solid line are selected for printing A0 and A1 drawings; Other A2, A3, A4 drawings choose thick lines, thin solid lines. It is best to convert to PDF printing.

What is the width of the solid line? This question should strictly be done according to the requirements of the design code.

It is specified in the design code that the width of the thick line is assumed to be b, the width of the medium thick line is b2, and the width of the thin line is < = b 4[ b is taken.

I have been working for the Municipal Design Institute for 25 years. For example, in the floor plan design of urban road design, the width b of the drawn line of the road shape line (thick line) is highlighted;

The buildings on both sides of the road, which are not the main structures of the plan in this road design, use medium thick lines, so the line width of the drawing is (b 2=;

The topographic map on both sides of the road uses thin lines, so the line width is (b 4=) and the map is plotted in color 8 (gray).

Thin solid lines, dashed lines, dotted lines or something are just the default, and the thick solid line is.

The reason why thin lines are still drawn after setting the line weight is because the Line Weight display is not turned on. The line width can be displayed simply at the bottom of the CAD.

To print the line width normally, it is not only necessary to set the line width correctly, but also to set the print style table reasonably when printing.

What line weights do: control printing.

Line weight is a basic property of CAD drawings, which can be set by layers, or you can directly select objects to set line weights individually. The standard line width is11。

The first thing to note when you see these values is that these values have units, and the unit is millimeters (mm). Of course, the unit of line width can also be set to inches (in), if it is set to inches, it will be047" and a series of values.

CAD drawings usually do not have units, but they can also be set to a variety of different units. In short, the units of CAD drawings are varied, and can be represented by one unit of 1 millimeter, or 1 meter, 1 inch; And some designers don't draw at 1:1 sizes; When printing, different print split ratios are also selected according to the graphics and paper size, such as :

200。Regardless of how the units and scale of the drawing are set, the units of Line Weight are always constant, and Line Weight is a basic property of the drawing object, but not a geometric property, which means that the Line Weight setting does not change the appearance and shape of the shape.

Using the Polyline command (the third one of the drawing tools, like a lying j) and typing w will prompt you to enter the width of the starting point (e.g. 5), and after entering it will prompt you to enter the width of the endpoint (e.g. 5). It can also be used to draw arrows with a starting width of 5 and an endpoint width of 0.

If it is line or arc, you can use the pedti command to change it to a pline line, and the pline line can be set to the width with pedit-w.

If it's a circle, I just know that I can draw it with donut to calculate the inner and outer diameters.

If you just want to print wider, you can set it in the style, but it is not easy to control, because most people don't know the printing ratio when drawing.

This is a multi-line drawn by the pl command or the rec command, and the line width is entered at the time of drawing.

Question added: What if it is drawn by PL or REC.

You can use the key combination "Ctrl+1" to open the feature, and then select the line, and there will be the property of the selected line on the left.

Change the "Globality" value in the geometry to 0.

This seems to have to be done first, first use pl to set the line width you want to draw one, then he will become the preset! But this is no different from giving line width at that time! pl + w will do.

If it is a polyline, then modify the command as follows, right-click the line to select the polyline in the pop-up dialog block, enter the line width w enter, enter 0 enter, just this line width is 0, you can also set the width as needed.

If it is a straight line, just select the line and adjust the line width in the properties, or turn off the line width setting under the All Orders bar (do not check Show line weight).

The explosion in front is a line of enlightenment. Press the fill command, then type off to close, and the regeneration is a box. Personally, I don't think it's possible, after all, it's a line to change into two, it doesn't seem like that.

Modify in the Quiet Source Management layer.

Select the whole image by boxing, and change the line width and color in the features; You can click on a filled color and press the delete key to delete it, or you can double-click on a filled color to open the hatcher.

You can directly select the similar ones, select the solid lines, right-click the similar ones, select all the solid lines, and then put them on a certain layer to modify the line width color of the layer.

It's best to put it on a different layer so that it's easy to modify.

Select the line you want to change the line weight, and then select the line width that meets the requirements from the line width option.

If you want to show a line-weight drawing, you have to click the line-width button above the status column.

The thin solid line is the default line weight, while the thick solid line is the line weight.

In mechanical drawing, the thick line is selected for printing A0 and A1 drawings, and the solid line is fine; Other A2, A3, A4 drawings should be thick and thin, and it is best to convert them to PDF printing.

The blue dotted line (ACAD ISO02W100) mm, the red dotted line (ACAD ISO04W100) is mm, and the double dotted line (ACAD ISO05W100) mm. The rest of the linetypes can be set by yourself.

Linetype definition consists of:

1) Header line: It is composed of the name of the line type and the description of the line type, the title line is marked with "*" as the beginning, the name and description of the line type are separated by a comma, and the grid code formula is:

linetype-name [,description]

2) Pattern line: consists of an alignment code and a description of the line type, separated by a comma in the middle, and its format is:

alignment,patdesc-1,patdesc-2, .Alignment codes, line type specifications....）

For example, the definition of border in the file is as follows:

where the alignment code "A" indicates that the linetype is aligned at both ends, and AutoCAD only supports this alignment.

1. Use the mouse to click the CAD icon at the top of the computer desktop, and then you will enter the operation interface of the CAD. Click on the Open icon command on the interface, or select the File — Open command.

2. Click Format at the top of the interface, find the line width command in the drop-down box, and click with the mouse to activate it. Or we can directly enter the lineweight command in the command and operate according to the following command.

3. At this time, a window will pop up in the interface, and in the window we can see the display-linewidth command. Inside, we can set up the lines. In fact, it is to set the linetype before drawing the drawing.

4. Click OK when the setting is completed. If you find an error in the drawing, you can use the tools on the left side of the interface to correct it. Of course, there are also some CAD drawing commands in the right window of the interface.

5. After the drawing is completed, it is necessary to view the CAD drawings to facilitate the next viewing. At the top of the interface, there is a command to save the icon; Select Click on the file in the top left corner of the screen – save as well.
