CAD Annotation Issues!! If you don t understand, don t answer blindly. Well answered, extra points!

After you draw a large frame, you are drawing a frame, for example, if you want to print on a paper, then draw a 297 420 frame, of course, if the original is available, you can insert it directly. Then enlarge the frame until it fits exactly enough to frame the drawing you are drawing, and the magnification of the frame is your production scale. Then enter the command d to press enter, open the dimension styler, and modify the "Global Scale Factor" under the "Main Units" tab to magnify the multiple for you.

Others are usually just the ones that are left by default (of course, you can change the colors, layers, etc.). This makes it possible to annotate dimensions that conform to the drafting standards. I've always done that.

Don't scale the graphics you draw. In addition, you should make some commonly used frames as tiles for easy use.

In addition, I will tell you about my experience with CAD for many years.

Dimension Style : The line exceeds the dimension line 125

Symbols and arrows Arrow size: 300

Text Text Height: 300 Vertical Top: Horizontal: Centered.

Offset from dimension line: 200 Text Alignment: ISO Adjustment Options: Arrows.

Main unit: Eliminate zero: Follow-up.

Others are adjusted as needed.

If you plot in the layout, the default value is 1).

If you draw a picture in a model, it depends on how large the scale and how large the format you want to produce.

You can mark one first, until the adjustment is appropriate, and then mark the others.

You can't have accurate data for you without proportions.

CAD annotation is a very important part of computer-aided design (CAD). It is mainly used to mark and illustrate various sizes, shapes, positions and other relevant information in design drawings, so as to facilitate the accuracy and standardization of the production and production process. In CAD software, this task can often be accomplished by using different annotation tools.

There are some common problems that need to be paid attention to and solved when making CAD annotations. The first is the location selection of the annotation, which needs to be decided according to the design requirements and the importance of the size, so that it is easy to read and understand. The second is the standard use of labeled symbols and words, which need to follow relevant standards and specifications to ensure the consistency and accuracy of labeling.

In addition, it is also necessary to pay attention to the clarity and readability of the annotation to ensure that the annotated information can be clearly conveyed to the relevant personnel.

There are several ways to solve CAD annotation problems. First of all, you can be familiar with and master the annotation tools and functions of CAD software, and flexibly use various annotation tools to meet different design needs. Secondly, you can refer to the relevant standards and specifications to understand the requirements of labeling and the regulations of the group to ensure the accuracy and consistency of labeling.

In addition, communication and collaboration with team members is also an important way to solve problems, communicate and resolve questions and confusion in annotations in a timely manner.

All in all, CAD annotation is an indispensable part of the design process. By mastering the annotation tools of CAD software, following standards and specifications, and effectively communicating and collaborating with team members, various problems in CAD annotation can be solved and the quality and accuracy of design drawings can be improved.

If you're using CAD software and you're experiencing inconsistencies in measuring lengths with others, there are a few possible reasons:

1.Unit settings: Make sure you and everyone else are using the same units of length, such as meters, centimeters, feet, etc.

In CAD software, you need to make sure that your plot unit settings match someone else's. You can enter it from the command line"units"command to view and modify unit settings.

2.Ruler Size: Check the scale setting of the ruler in your CAD software to make sure it matches the scale of the actual drawing. In CAD software, you can use the Scale command to adjust the scale of the drawing to match the actual situation.

3.Measurement method: Use the correct measurement method to measure the length.

In CAD software, you can use the Measure command or the ruler tool Hail Spring to measure lengths accurately. Make sure your measurement method is correct and that the corresponding measurement tool is set up correctly.

Also, if you're measuring and annotating drawings after receiving them from someone else, make sure they're complete, accurate, and unruly and haven't been scaled or distorted.

In any case, be sure to double-check and check the unit settings, ruler scaling, and measurement methods to ensure accurate measurements and callouts.

First question:

Second question:

If you are prompted to specify the location of the witness line as usual, enter the parameter m (multi-line text).

Before positioning the cursor and the size number, enter "%%c", automatically convert to a diameter symbol to position the cursor at the end of the size number, enter the capital letter h and the number 11, then enter the parentheses, then enter the upper deviation +, then enter (shift+6), then enter the lower deviation 0, select all characters between the upper deviation and the lower deviation, and right-click - stack.

For the first question, you only need to enter a in the datum box, as shown in the figure below;

2.The second question, double-click on the marked number, go into yourself, such as you want to enter %%c50h11(+, select the + box on the point stack (a b) on it!

The main equipment or auxiliary equipment should be positioned with the axis of the building, and the auxiliary devices or auxiliary equipment of the main equipment should be determined with the relationship size with the main engine. For the equipment arranged at an angle, the elevation of its starting point and end point should be marked, and if there is a turning point in the middle, its elevation should also be marked, and the angle of inclination of the equipment should be noted. The floor and platform of the building should generally note the top elevation, and the roof should be marked with the elevation of the bottom of the beam to indicate the required clearance height in the data drawing, and other roofs should also be marked out if there are clearance requirements.

In the finished drawing, you can change the roof elevation, the column is represented by the axis, and the axis should be numbered to the building and structure drawings of the workshop. Each equipment and platform must have a three-way positioning size, if a device appears on several planes or sections, its size should be represented in detail on the main flat and cross-sectional surfaces, that is, a size should be represented on two surfaces, and the rest of the surface only represents the main positioning size, if the size of the equipment needs to be noted a lot, only the main positioning size is noted on the layout drawing, and other detail dimensions are represented on the enlarged drawing. The size number should be concentrated on both sides of the figure (mainly on the right side), and below, with the outermost edge of the figure about 15mm (actual size), if it is difficult to note outside the figure or unclear expression, it can also be noted in the figure, but it should also be appropriately concentrated; The spacing paper of the two parallel size lines in the concentration is 9mm (actual size), and the size of the column network is generally not noted in the graph.

The direction of the size number should be consistent with the direction of the drawing, and the rush point of the dimension line is represented by a slash, and the direction of the slash line is required to be as follows: The size number should be written in the middle part of the upper part of the size line, if the spacing of the dimension line is too small, it can be marked in the appropriate place with the extension of the lead line. As shown in the figure below, more than two size lines, the rest of the size lines should avoid crossing, should be noted first sub-size and then the total size, the end of the size line and the size line should cross each other about 2mm is appropriate, as shown in the following figure:

Note the diameter, radius or other inclined dimensions, according to the 30° demarcation specified in the direction of the note, as shown in the figure below, try to avoid marking the size within the range of 30°, and use the drawing line to draw out the dimension. When you call a diameter or radius, the diameter number is preceded by , and the radius number is preceded by r. When the diameter or radius of the drawing is too small, the number can be annotated outside the drawing.

As shown in the figure below: If the radius of the center of the arc is too large to be represented within the view frame, and the radius must be indicated, it can be marked as shown in the following figure. As shown below:

The contour lines, center lines, and dimension boundaries of various graphics cannot be used as dimension lines, and the dimension lines of the graphics that are cut by the break line cannot be cut.

Component positioning and the interrelationship between main components. The large size wraps the small size, neat and clear.

The most important thing is to express clearly, to achieve the design intent, followed by aesthetics.
