Teach you how to convert cad to coreldraw

Q: What are the methods and techniques for importing CAD files into Coreldraw?

How can I enter a DWG file into coreldraw? Why does it appear after the input "The selected filter cannot be entered" or "Do not support this format"?

A: First of all, to ensure that the CD supports input only in the format, CD commonly used input formats are: cdr, psd, eps, wmf, ai, cmx, pdf, gif, jpeg, bmp and other image formats However, many other vector software's own formats need to be converted before they can be imported into the CD. In principle, the CD supports the direct import of DWG, but in practice, it can lead to graphics errors, or the problem can not be guided at all. The solution is to directly export the CAD file into EPS format and then put it into the CD. Note that the CAD is first converted to a white background before the output EPS.

Theoretically, Coreldraw can draw complex drawings and electronic diagrams, but its strengths are not here, which may be the best of AutoCAD. However, if you want to make a graphic document in Coreldraw, an explanatory technical manual, etc., or a lot of graphics for filling and filling patterns, you need to import the files in AutoCAD format through the graphic format exchange.

After personal practice, a more feasible method was found. (Source)

Before explaining this method, the first thing to explain is that in theory, Coreldraw can directly open or import files in *.DWG,

*.DXF format, but I I have tried it and the effect is not satisfactory. Even if the AutoCAD standard graphics exchange format file (*.DXF file), the effect of importing Coreldraw is not very good, it is difficult to maintain the original appearance of AutoCAD file, and sometimes even beyond recognition, as shown in Figure 1. At this time, you can't use Coreldraw to describe it a little bit more? If you convert to bitmap format import, the effect is not good, and the file size is too large.

Then let's try the following method first. Taking AutoCAD R14 and Coreldraw10 as examples, the basic idea is:

AutoCAD -> DWG file -> Export to WMF file -> Import to Coreldraw -> Further processing, convert to editable Vector graphics files, as long as you handle everything in Coreldraw, you can export to AI, PS, EPS and other formats, you can easily do pre-press, printing work. Ok, let's get down to business, let's take a look at this comparison & ldquo; stupid & rdquo; but a very practical method.

1. Draw graphics in AutoCAD R14, select Tools-> Preferences->Display->Color to change the background color to white (Otherwise the attached image will have a solid black background), click “OK”.

2. Go back to the drawing window and you will see that the background has become white.

3. In order to display smoothly and accurately in AutoCAD, enter the command Viewres, set the variable, and increase its value, such as 10000. Otherwise, not only is the display not sufficiently fine and smooth in CAD, the graphics imported into Coreldraw will be out of shape, and the common one is that the circle becomes a polygon. In the command line, type Pan (Pan) -> right-click menu and select "Zoom Eextens" to place the graphics as large as possible.

4. Select the graphic to be output, and select “Export” from the “File” menu to select the output as the wmf file format.

5. Go to Coreldraw and create a new document. Right-click on the workspace and select “Enter” (or use the shortcut key Ctrl+I) to select “Wmf format” from a large list of supported file formats, select the Wmf file you just exported, pull out an object frame, and import . How unfortunately, the graphics we need are closely integrated with a large blank (I think this is the white background in AutoCAD), white takes up space, and editing is very inconvenient.

6. Don't give up the selection, click “cancel group" on the property bar (note that not all groups are canceled), separating large blanks from useful graphics. Press ESC to cancel all selections, click on the large blank of the input Wmf graphic to select it, delete it, you can remove the blank, as shown in Figure 6. (In order to be clearer, the blanks in the figure have been filled in blue), leaving only the useful graphics we need.

7. You will find that the graphics after deleting the blank can be moved, copied, stretched, set the outline width, edited with the shape tool, filled, etc., and the text can be edited well. Ok, it is restored to a vector! In fact, AutoCAD draws the original vector graphics.

8. You can also try to export AutoCAD files to EPS format, and then import them into Coreldraw.

However, please note that if the drawing in AutoCAD is too complicated (such as pattern filling), after inputting to Coreldraw, the group is dismissed. After selection, the status bar displays information for hundreds of objects. The processing speed will be slower. If the machine is not cool enough, this method is best not to try.

9. After deleting the useless background, the file imported into Coreldraw is already a vector graphic, and after some processing, it can also be output as a vector graphic format such as AI, and then open into Illustrator for detailed and detailed After many settings and prepress processing, you can print or print.

The method described above should be sufficient for general CAD graphics, and the following questions are worth noting:

1) Whether it is dimensioning or text in AutoCAD, some special symbols such as &ldquo ;φ”,“±” etc., is expressed in a special way (such as %%C, %%P respectively, “φ”,“±”), after import Coreldraw doesn't know the convention of AutoCAD, or faithfully represents it as it is.

I haven't solved this problem yet, so I have to redraw the symbols such as “φ”,“±”.

2) In AutoCAD R14, some Chinese font input method input symbol fonts such as “μ”“Ω” etc., after importing into Coreldraw, if opened on other computers, If other computers do not have corresponding fonts, they will not be displayed correctly or even displayed. The solution to this compromise is to turn it on the other computer in Coreldraw by first turning it into a curve (Ctrl+Q).

3) Generally speaking, the text in AutoCAD is still text instead of curve after importing Coreldraw, which can be edited with text tool. However, some text features in CAD are difficult to guarantee that they will not change or be lost. This also needs attention.

4) Dimensions and pattern fills in AutoCAD are all integrated. After importing Coreldraw, it will be “exploded” into smaller and smaller objects.

5) Sometimes it is necessary to add the graphics lines imported into Coreldraw to thicken. I thought of the new function of AutoCAD2000's "Line Width", so I opened the line width display, set the line width value in CAD, and imported the WMF file into Coreldraw according to the above method. The result is very unsatisfactory, almost a thick black piece. There is no way, it is a problem, and I have to give up. Or select the line to be bolded in Coreldraw, and set the line width after combination.
