Urgent for answers to CAD scale questions!

The frame is 1:50, which means that for example, the A2 frame was originally 594x420, but now it needs to be reduced to half and use the size of 297x210. 1:: Available when drawing

1 scale to draw, the original picture is 4000 to draw 4000, but the global scale of the size should be 1:50, and the measurement ratio (scale factor) is still 1:1.

If the frame can't fit, then change to a larger frame, for example, if A3 can't be placed, change to A2, A2 can be lengthened with A2, or use A1....The printing scale, generally the formal drawing, the frame is 1:50, and the printing scale is also 1:

50, if it is not printed to scale, it can be set casually.

Find a template, how much proportion to set directly on the line, the size of the annotation will match the proportion of the setting, the thick line of the center line will be drawn into their own layer, don't deliberately put the line on that layer, search on the Internet, the university also encountered this situation, I feel that the processing method there is too stupid, I found that it is not like that at all, each company has its own template, there is no need to set so much, it is very simple, look for learning on the Internet, there should be a lot. The drawing is definitely an 1:1 drawing.

Print and select the box directly.

The smaller the scale, the smaller the frame.

In the case, you use a few frames, which also has a relationship with the size of A3 420*297

Yours is only 4m and you can definitely put it down.

Frame: Determined according to the size of the drawing and the size of the paper that the printer can print, etc. Generally A4 or A3, etc. There are ready-made insertion frames in CAD. Personally, it is not recommended to scale the drawing drawing, if the 1:1 frame is not small, then enlarge the frame.

The order in which I draw is to choose the frame first, and determine the appropriate scale according to the size of the drawing to be drawn. After the proportions are determined, the corresponding labels and numbers in the figure should be adjusted up accordingly. Generally, the text or numerical values can only be seen clearly when they are printed, so if you enlarge the frame by 50 times, then the height of your text or number should be set to the height of (, so that the printed things will be seen clearly and coordinated.

In addition: if you want to use SC to scale the drawing, you don't want to mark the changes in the numbers, you can define the drawing into blocks first, and then zoom.

Good luck!! Hope it helps.

It's okay to draw a frame as a frame, but if you want to put the picture on the A3 paper, you must set the frame according to the A3 frame to fill the A3 paper.

It's the ratio of the picture you draw to the real thing.

The ratio and output do not conflict. If you draw according to 1:1, then you mark the actual size, and you can adjust the size in the layout, and the size will not change.

You can see how to do it from the layout window below. The output has nothing to do with your scale settings.

Before drawing, you must first set the size of the frame, that is, how big the frame you want to place the picture into. The standard frame of A3 is 297*420, and the graphics are generally drawn according to the actual scale, for example, if you want to draw a 500*800mm rectangle, then the standard A3 frame needs to be magnified 2 times to accommodate the actual graphics you draw. However, the corresponding annotation size and text size must also be magnified by 2 times.

The text on the printed drawings can conform to the national standard. There is an easy way to set the dimension text and arrow size, which is to change the "style" - annotation style - adjust the "- global scale", and change the global scale to the multiple of the frame magnification. A3 magnified by 2 times, then just change the global ratio to 2, and nothing else needs to change.

Text and annotation are part of the diagram, the drawing you want is 140*240, even if the frame is enlarged, when the diagram is drawn, the diagram frame and diagram are uniformly reduced to 140*240 range, at this time, the graphics and text are reduced accordingly, so it may make the text not the size you want or even too small to see clearly.

There are many online tutorials on the problem of output, and you can understand it by looking at it, which is much clearer than listening to the description of the text. Hope it helps.

Questions about the scale of the drawing:

In fact, when CAD drawing, as long as you don't zoom in and out. The length of the line segment will not change. For example, you are in 1:

The 1000-long line drawn at 1:1 and the 1000-long line drawn at 1:100 are the same in the diagram, and this size is the actual size of the figure, which I call the measurement size (which can be measured with the di command).

The difference is the plot scale, and the current software will adjust the size of the frame and font according to the plot scale you set when inserting the frame and writing the font. For example, if you insert an A3 frame in a 1:1 ratio that is 420*297, the measured size is 420*297;And in 1:

The A3 frame inserted under the scale of 100 is written as 420*297, but the size measured after the actual insertion is 42000*29700.

Therefore, we need to control the font size and graphic size when the image is plotted, as long as we control the scale of the plot. This is important when inserting someone else's graphic. For example, the frame when I decide to print is 1:

1. When inserting (Tianzheng or Explorer), change the ratio under the insertion command to 1:1, and the inserted frame (take A3 as an example) is 420*297. At this time, put the picture you drew into the frame, and the scale of the print will be 1:

1, that is, 1 mm on the printed A3 diagram is 1 mm of the actual object. This is estimated to be only used by people who draw parts, and most people will find that the frame inserted in this way is so small. Hehe, of course, because you don't want to draw 1:

1 drawing, take 1:100 as an example, you write in the drawing that the ratio is 1:100, the actual meaning of this sentence is to ensure that after your drawing is printed, the measured size of 1 mm represents the actual 100 mm.

At this time, you should enlarge the 1:1 frame you inserted by 100 times, and then put the picture in, the frame in the picture is magnified by 100 times, but the size of the actual printed drawing has not changed, that is to say, the content in the frame is 1% of the size of the actual object after printing. This also achieves 1:

The practical meaning of 100.

The 1:1 frame magnification of 100 times mentioned above is the same as when the frame is inserted to 100, and the annotation is the same, so the annotation and the frame should maintain a ratio to ensure the size of the printed font).

In the same way: if you want to insert a 1:100 in the frame

10 figures, then magnify 1:10 graphics 10 times. At this time, pay attention to you 1:

The font height of 10 should also be magnified by 10 times. It can be made into blocks and then enlarged.
