CAD common shortcuts and how to quickly improve drawing ability??

1. To improve the speed of mapping, users should follow the following principles of mapping:

1 Drawing steps: Set the view frame, set the unit and precision, create several layers, set the object style, and start drawing.

2 Always use a 1:1 scale for drawing. To change the size of the drawing, you can set different print scales in paper space when printing.

3 Set different layers, colors, and lineweights for different types of element objects, and the color, linetype, and lineweights of the element objects should be controlled by the layer.

4 When you need accurate drawing, you can use the raster snapping function and set the raster snap spacing to the appropriate value.

5. Do not draw the frame and the figure in the same drawing, insert the frame into blocks in the layout, and then print out the picture.

6 For named objects, such as views, layers, blocks, line types, text styles, plot styles, etc., the naming should not only be concise, but also follow certain rules to make it easy to find and use.

7 Set some common settings, such as layers, dimension styles, text styles, raster snaps, etc., in a drawing template file (i.e., save as *.).dwf file), which you can click in the Create New Drawing wizard when you draw a new plot later"Use a template"to open it and start drawing.

2. Choose the right command

The user is able to harness AutoCAD by issuing a series of commands to it. When AutoCAD receives a command, it immediately executes the command and completes its corresponding functions. Although there are many ways to achieve the same goal, if the command is selected properly, the operation steps will be significantly reduced and the drawing efficiency will be improved.

Here are just a few of the more typical examples.

1 Generate a line or segment

1) In AutoCAD, line, xline, ray, pline, and mline commands can be used to generate straight lines or line segments, but only the line command is the most frequent and flexible.

2) To ensure that the object is between three views"The length is right, the width is equal, and the height is flush", you should use the xline and ray commands to draw a number of auxiliary lines, and then trim to cut off the excess.

3) If you want to quickly generate a closed fill boundary, or if you want to construct a region, you should use the pline command. Segments generated with pline can be performed using the pedit command.

4) When multiple line segments are generated parallel to each other at a time, and each line segment may use different colors and line types, you can select the mline command.

2 Annotated Text

1) When using text annotations, if the text in the annotation has the same format and the annotation is very short, use the text(dtext) command.

2) When you need to write a large paragraph of text, and the text in the paragraph may have different formats, such as font, character height, color, special symbols, molecular formulas, etc., you should use the mtext command.

Learn and master a variety of shortcut commands. If you want to be fast, you can't reach it, and if you want CAD to draw faster, you can directly let the big guy take you.

Find a good textbook, learn more and practice more;

Find a good software, PCCAD.

1.Shortcut key.

2.Practice more.

3.Whatever you draw, be confident, know what you're drawing, how to use layers, etc.

In fact, there is no skill, and if you skillfully apply every command, the speed will naturally go up.

You can memorize shortcut keys for some common commands, understand the characteristics of straight lines, circles, rectangles, regular polygons, etc.

Set up your own drawing template, set the unit, layer, annotation format, text format, etc.
