How to speed up your AutoCAD drawing

Most people know this, as the ancients said: Practice makes perfect. Basic commands and shortcut icons are the most familiar in CAD, so I won't elaborate on them.

Second, ACAD. PGP file modification

As we all know, the LINE command can be simplified to L when inputting commands. Why? Because ACAD has an encrypted file. Define PGP of LINE command abbreviation in AutoCAD, first find this file and open it. Find the prompt "Examples include the most commonly used commands." You can define shorthand in the following lines. Remember, the left column is the text realization of shorthand command. Can be modified as needed (of course, you are familiar with the English abbreviation), the right column is the default command. Please don't modify it at will. I believe this will improve your speed.

Third, graphic pinch operation.

Squeeze it. Have you ever used it? When you click the chart with the left mouse button, many boxes will appear on the chart. These are handles. By controlling grips, you can perform some basic editing operations. Such as: copy, move, change the graphic layer and other basic operations. And its special operation. For example, a straight line has an extension operation.

Fourth, extensive use of modification commands.

For CAD draftsmen, it is not difficult to understand that 60%-70% of a drawing is a modification and only 30%-40% is a drawing. From the perspective of graphic composition, there are only two kinds of graphics: straight lines and curves, and curves are cut by a large number of circles, so a picture is finally composed of straight lines and circles. In this case, you only need to draw a circle or a straight line and determine the position, and then perform a series of operations such as offset, trimming, fillet, array and chamfering. To realize graphics.

For example, when drawing a bearing, only two perpendicular straight lines are needed, and then a series of operations such as offset, fillet, chamfer and so on are carried out, so that the drawing of the bearing can be accurately completed.

Five, building blocks simplify the drawing work.

Block is the core work in CAD operation, and many programmers and drawing workers have established various blocks. Because their work brings us convenience, we can use these tiles like bricks. For example, gears and bearings of various specifications are established in engineering drawings; In architectural drawing, some doors, windows, stairs, steps, etc. It is set to be convenient to call when drawing.

Among these blocks, the flexible block is the most easily called, and it is actually a program written in Auto LISP/Visual LISP. If you want to learn the book Visual LISP tutorial, please recommend it. I mainly introduce the establishment and call of external blocks of graphics.

1. Create a DWG file of the pattern prototype and save it (for the operation under the WBLOCK command, the base point of the block should be established for the subsequent call).

2. Add a collage to the graphics that need to be inserted.

Through these two parts, you can create and use blocks. The use of tiles will further improve the drawing speed.

I hope this article can help beginners who want to improve their drawing speed.
