AutoCAD drawing skills

First, AutoCAD table production

AutoCAD even though there is a powerful graphics capabilities, but relatively weak function of treatment table, and in practical work, are often required in the production of AutoCAD at a variety of forms, such as the quantity of work, etc., how efficient the production table, is a very practical problem.

In the AutoCAD environment manually draw lines drawn Ways table, and then fill out the characters in the table, not only inefficient, but it is difficult to precisely control the location of language writing, language typesetting is also a problem. Even though AutoCAD support Object Linking and Embedding, you can insert a Word or Excel table, but to amend it on the one hand, not very convenient, one small modification must enter the Word or Excel, modifications are completed, again back to AutoCAD, on the other hand, some special symbols such as symbols, and in the secondary level of reinforced steel bars and other symbols in Word or Excel it is difficult to enter, then there is no way to do the best of both worlds, through exploration, it can be better addressed: first at the system end table in Excel, copy it to clipboard, and then in the AutoCAD environment edit menu select Paste special, as select AutoCAD Entities, determined after the table that is converted into AutoCAD entities using explode explosion, that can edit one of the lines and side character is very convenient.

Two, in the Word document to insert AutoCAD graphics

Word document production, it often requires a variety of illustrations, Word graphics limited, especially in complex graphics, the more apparent disadvantage, AutoCAD are professional mapping software, powerful, very fit rendering complex graphics, good graphics rendering using AutoCAD, Word then insert the production of composite documents are a good way to solve the problem, you can use the EXPORT function to provide AutoCAD first AutoCAD to BMP or WMF graphics format, such as output, then insert a Word document, you can first copy of AutoCAD graphics to the clipboard, and then at Word document and paste. It should be noted that because of AutoCAD default background color is black, and the Word background color is white, first of all AutoCAD graphics background color should be changed to white. In addition, AutoCAD graphic insert Word documents are often empty edge is too large, the result is not satisfactory. The use of Word Pictures Toolbar on cutting function and carry out rectification and air side is too large to resolve the problem.

Three, linewidth modification

AutoCAD provides a polyline linewidth modify command PEDIT, to carry out many line linewidth changes (if not for the polyline, the command will be transformed into multi-line, and then change its width), but the operation PEDIT Fan, each time only to select an entity to operate and inefficient. AutoCAD R14 comes with Bonus program provides mpedit orders for bulk modify polyline width, a very convenient and efficient.

AutoCAD2000 at Medium, but also to the entity designated linewidth (LineWeight) linewidth property modifications, simply select to change the linewidth of the entity (entity set) and change the line width can be property, linewidth modification more convenient, it should be noted , LineWeight property linewidth at the display screen is determined by system variables WDISPLAY, the variables for the ON, while at the screen LineWeight linewidth property, the variables OFF, do not show. Polyline with LineWeight linewidth linewidth can be controlled entities, the distinction between the two are, LineWeight linewidth linewidth are absolute, and many line linewidth linewidth is relative, that is to say, no matter how much graphics to size Print, LineWeight linewidth are unchanged, but the polyline width is the ratio of print size with the size of change, order LineWeight linewidth scale of no impact, no matter how many times zoom entity, LineWeight linewidth are unchanged, but many line linewidth is scaling with the change.

Four, graphics, printing techniques

Because the printer is not installed or want to use someone else enter the high-end printers AutoCAD graphics, need to go print AutoCAD-based computer graphics, but the other computer may not install AutoCAD, or because for various reasons (such as AutoCAD graphics on the computer in another font to display abnormal, through the network printing, network printing is not normal, etc.), should not use other computers to engage in normal print, at this time, you can at their own AutoCAD computer graphics print to a file, the formation of printer paper, and then at another computer on using DOS copy command to the printer file output to the printer, the method: copy prn / b, it should be noted that, in order to use this feature, you must add the other in the system on a specific model of computer printers, and set it as the default printer and another, COPY not to forget after the final add / b, show that the binary form of the printer file output to the printer.

Friday, selection techniques

Users can use the mouse to select one by one goal, one by one to select the goal of selection is added to focus on the other, AutoCAD also provides Window (to type "w" in response to Select object: or directly on the screen from right to Zola a rectangular box in response to Select object: prompt), Crossing (to type "C" in response to Select object: or directly at the screen from left to right on a rectangular box in response to pull Select object: prompt), Cpolygon (to type "CP" in response to Select object:) , Wpolygon (to type "WP" in response to Select object:) and many other window mode selection objectives, one of Window and Crossing for the rectangular window, and Wpolygon and Cpolygon for polygon window, in the Window and Wpolygon mode, only when the entity all parts have been included in the window, only selected entities, and in the Crossing and Cpolygon manner, as long as the part of entities included in the window, the selection entities will be like.

AutoCAD also provides Fence means (to type "F" in response to Select object:) select entities, do not draw a closed polyline, and the broken line intersecting all of the entities was selection. At select targets, sometimes accidentally select the wrong selection of targets, then the user can type R to respond to "select objects:" prompt, and then mistakenly put some of the objectives of the election to concentrate removed from the selection, and then type A, again Choose to add the target to focus. When the selection of entities and other entities can be close together at the same time hold down the CTRL key, and then click the left mouse button continuously, then immediately followed by an entity with high-brightness display, until the selected entities, high-brightness display, and then press the enter key (or click the right mouse button), the selection of the entity. Entities can also be conditional selection, which uses' filter in response to select objects:, at AutoCAD2000 also provides a way QuickSelect select entities, functions and a similar filter, but the operation more easy and convenient. AutoCAD selection provided by the constructor function sets a strong, flexible and appropriate use of graphics can greatly improve efficiency.

Six, the quality of property inquiries

AutoCAD to provide point coordinates (ID), the distance (Distance), size (area) of the inquiry, give graphical analysis has led to great convenience, but in practical work, and sometimes need to query the quality of property characteristics of entities, AutoCAD providing a physical the quality of property inquiries (Mass Properties), can easily query entities moment of inertia, area moment, center of mass and other entities, it should be noted that, for curves, polyline closed tectonic region, should be ordered by region will be closed regional noodle domain , and re-implementation of the quality of property inquiries, the moment of inertia in order to query entities, covering an area of moment, physical property, such as the mass center.
