CAD作图

CAD作图 I have 6 years of experience in the use of CAD, I have done before the industry is hardware processing, have seen a lot of foreign drawings, also summed up some experience, today is very pleased to share with you how to clearly express some basic methods of drawing, we hope to be able to help, if there are written in the wrong position, also please put me first thank you here. CAD is broad and profound, I also dare not say extre mely subtle, proficient in CAD, after all, I'm just a few of them know it, I hope someday to find a CAD master each other. Here are a few points. I think if you can do this, no matter whether the drawings are very professional, at least it seems to be simple and easy to understand, and now share with you: The 1. layer should be sorted: To take the layer set color, line type, line width setting, it is necessary to set up a print that I have seen many drawings, in which, a lot of people are all the objects are stored in the 0 layer, such drawings if some objects you want to select one of the really is an easy thing to do; some people paint color, line width, line all is the default, on the whole is a white, a linear, confused center line, solid line and hidden line, finally, no matter how you look at is very confused. When I draw a picture, I want to have a good layer. I prefer to use English names to partition the layers as follows: The Solid layer is used to place the solid line. The line uses the default Continuous, the color is white, and the line width is 0.25mm; The Center layer is used to place the center line, the line type is center, the color is red, and the line width is 0.15mm; The Hidden layer is used to place hidden lines. The line type is Hidden, and the color can be 0.15mm with 253 light gray line width; The Screw layer is used to place thread, line Hidden, color 33, and line width 0.13mm; The Hatch layer is used to fill the line, the line can be Continuous, the color is 66 dark green, and the line width is 0.09mm; If you need to add other layers, lines, colors, line widths, try not to set them up so that you can see the drawings better. It's better to manage the drawing more easily, and it's much easier to modify. 2. fill in the problem: Believe that many friends outside the processing are clear, many foreign maps fill are very ugly, because most of the fill color is very bright red or red or blue, has not yet begun picture has been filling pattern to those eyes, and print out the drawings also looks like it don't look good, they mostly use the Default line width, drawing will look a bit no secondary sense. I suggest that the drawings of the drawings fill the pattern with ANSI36, which is a dotted line. The width of the line is 0.09mm, so the printed pattern will not be too subjective, and it looks very refreshing. If the same drawing has different material parts, it can be filled with other patterns, but not the same as the existing patterns, This preliminary look at the material will be different. 3. mark questions: Would you have seen some of the drawings on the label when tagging is 100 and the actual length is only 79.91 this phenomenon? That figure no drawings in accordance with the proportion of painting, there is a diagram of the will to change. I feel very bad about these drawings, and most people like to use ed commands to manually modify dimension values when drawing. There are some drawings are more puzzling, their annotations are broken, and all become one by one line, want to edit those diagrams, need to be difficult to delete a line, a line, and then re marked. I think no matter what figure do not use the drawing command ed to manually modify the size value, ED can only be used in some of the comments to add annotations, such as the 60 diameter dimension on profile on a diameter Phi like symbol. Manual ed to modify the size of the value of a harmful things have been, and often eventually there will be inconsistent proportion, or even a hole out of parts of the situation. We should draw all the pictures according to the proportion of 1:1, marking itself is also easy, tagging can set a number of styles, as follows: Don't use white for the size of the line (separate from the color of the solid line layer), The line width of the dimension line is 0.13MM (so that the size line is not considered to be a solid line over the printed drawings); The baseline spacing and starting offset are 1mm, Center mark with no, CAD own center mark is not good grasp, management and trouble, it is recommended to use Yan show toolbox central line, easy to get, and beautiful good-looking, A text style can specify a font that can display diameter symbols normally, The text color is green, Text height using 2.5 (A4 drawings with 2.5 is already very enough), The proportion of the marked features is set according to the proportion of the drawings. If it is a drawing of 1:2, it is set to use the global scale of 0.5, The accuracy of the main unit is accurate to 2 decimal places, and the precise drawing may require 3 decimal places, A decimal delimiter uses a solid point instead of a comma. The scale factor in the measurement unit is best not to change. 4. print I love to print is set up, and then following the application to the layout, this print settings will be preserved, simply do not need to set the point with the menu below to print, set up no matter how long you want to print without resetting the print. If the blueprint is to print only black and white, select monochrome.ctb in the print style list. If your printer is good, if you want to color it, change this item to "no". Generally do not suggest a color printer, because some color, green and yellow part will appear very dark, if you also need a copy of the drawings, the green and yellow lines will disappear oh! The above is a summary of the most common problems that some of my people have drawn when painting drawings. We can save the files from these settings into templates, So the next time you need to directly tune out of it, the specific method is: file, select "save as to save the graphics template type (DWT), and then save the OK! When the new file open the template, then everything is all set up. Next, I will introduce some of my CAD drawing methods, which will be published in the CAD forum. Please note that I hope you can get your support! Thank you!
