For questions about CAD scales, ask me a question about CAD scales?

Enemies!! When drawing, it is drawn according to the ratio of 1:1, and when drawing, if you want to draw on A4 paper, then follow 1:

1. Draw an A4 frame, then enlarge the frame 250 times, and then put your picture into the enlarged frame, when the scale of the picture you type out is 1:250, and so on, if you want your picture to be 1:50, enlarge the frame 50 times, of course, you want to use A2 or A3 drawings The drawing method is the same, you only need to draw an A2 or A3 frame, of course, use different proportions on a picture, just like the friend above said to use the layout, If you don't need a layout, it's a bit troublesome, so I'll discuss it next time.

Supplement: If you annotate like the friend above, it's too troublesome, if there are several proportions in a picture, then change it like you did, then you have to change the text size, arrow size, size limit size, and basically all the values of each annotation style anyway. If there are several proportions in a CAD file, you just need to create a new annotation on the basis of this standard annotation, but you need to change the value in the global scale in this new annotation to what you need (for example, the ratio you want is 1:

250 is 250 on the global scale**You don't need to change everything else, isn't it much simpler??

Yes, this is the easiest way to do it. The premise is that the ratio you set can be printed out on your paper without exceeding the boundaries of the paper, which can generally be checked with a print indication. In complex cases, such as printing several scales simultaneously on a single sheet of paper, paper space, or layout, should be used.

That's not true. The scale you lose later is the print scale. It's not the proportions you need.

Follow your 1:250 scale. If you draw one meter on the map, then you are 250 meters.

If you're actually 1m, then you're going to have to enter 4mm in CAD. Then change the unit of measurement scale factor to 250 in the "Main Units" tab of your dimension style settings. So you're marking 1000mm.

Wrong. CAD scale is used to standardize the text and annotation, each ratio corresponds to a text size and annotation size, drawing with the actual size is certain, but when annotating, you have to use 1:250 annotation, the text size should also be changed to 1:

250 text, to put it simply, if 1:1 when your text size is 1, then 1:2 when your text size should be used 2 and not 1 It's as simple as that, choose to scale according to the scale of the drawing when printing, don't choose other OK.

Agree with you,,, but it would be better if you could use layouts

1. First of all, you need to understand the concept of proportion. Check GB T14690<>

2. Check the first article. The figure here refers to paper drawings, that is, paper (PVC and other materials) drawings drawn (printed).

3. General CAD drawing, whether AutoCAD, SOLIDWORKS, etc., are drawn in the computer according to 1:1. However, when it is printed, it will be reduced or enlarged as needed, and the scale will be taken into account.

The scale of the annotation on the surface is also the print scale (or draw scale).

Label 4000 and the 4000 you measured out is the actual size of the drawing, 1:100 is the scale of the drawing, print according to 1:1 (the scale in the property column) printing, and the length of the printed drawing is 400 100=40

The dimension is the size of the drawing itself, and the scale refers to the ratio of the drawing printed on the drawing to the actual size of the drawing.

Because the print setting is 1:100, the 100mm measured in the computer is only 1mm printed

Tools Materials.

CAD software for computers.

Here's how. 1. First of all, open the CAD software and draw any drawing, as shown in the figure below

2. Then enter "sc" in the command bar below, press Enter, and then select the graph according to the prompts, as shown in the following figure:

3. Then the graph becomes a dotted line, as shown in the figure below

4. Then select a base point of the graph with the mouse and drag it, and right-click to confirm, as shown in the following figure

5. Set the base point according to the prompts in the figure.

6. The final setting is completed, as shown in the following figure:

Here's how to enlarge the scale of a CAD drawing:>2. To multiply the actual size of the graphic, you need to drag and select the graphic first, and select all the graphics.

3. In the command input box below, enter sc, and then press enter.

4. In the specified scale factor input box at the back of the graph, enter the multiple value to be magnified, and enter as many times as you want.

5. In this way, the size of the graph will be enlarged according to the singular number entered, and the whole graph will be enlarged in equal proportions, as shown below, the original size of the edge line is 8, and after entering 5 times, the value becomes about equal to 40.
