AutoCAD, MDT and other software integration [Reserved]

 A project often requires the use of several software and effective exchange of data to complete. Such as enterprise MRP Ⅱ / ERP systems, in general, should be included from the old drawings scanned raster image, and then editing software such as Photoshop, Scansmithpreditor; can be grating vector hybrid editing, part of the vector, such as AutoCAD Overlay, GTX, etc.; now common platform for 2D mechanical drawing AutoCAD; the integration of current and future development of the common 2D and 3D parametric 3D mechanical design platform MDT; CAE software such as WM Motion Mechanism Simulation ; finite element analysis WM FEA & WM Concept; CAM software, such as machining centers HyperCAM; sheet metal SMP, SPI; should also include CAPP, PDM and other related software. CAD graphic data system needs to be effectively transmitted to other CAE software for analysis and calculation or CAM software for manufacturing. a project often need to use several software to establish a direct synthesis of the strengths of the document such as: word processing using Word and forms a strong function of reference for the process AutoCAD drawings; with AutoCAD powerful vector graphics on the use of digital obtained by the camera or scanner raster image annotation or measurement. Now, I am AutoCAD, MDT integration with other software applications a little talk about personal experience, because the appropriate version of AutoCAD MDT include the appropriate version of the full functionality, so only, unless otherwise indicated MDT with the rest applies to both.
one, AutoCAD software to exchange data with other information
1, through a standard graphics format used for data exchange
AutoCAD DXF or IGES file formats international, the graph data transfer to other software for analysis and calculation, or processing, according to other non-mapping software within the data generated by the establishment in the AutoCAD graphics, but also to achieve AutoCAD and other CAD data conversion between the systems. for every AutoCAD developers are should spend some time learning DXF file format to the preparation of the required interfaces. using the DXF format, through the ; DXFIN TIFF, TGA, PostScript, JPG and other image grating input and output, more broadly applied to desktop publishing, high-quality printing, image processing, reality shows and animation applications. raster file output of (including BMP, TGA, PCX, TIFF) raster image, in the TGA, PCX, TIFF, PostScript) AutoCAD with database connection to allow access and operation of the database are stored in external non-graphic data, such as material list, parts list and so on. In the new AutoCAD 2000 features such as database connection management, data and other data with the browser Graphics, query, modify and update more convenient, and provides a structure for the application development, advanced database applications, and features C + + API interface. In AutoCAD 2000, choose Connection data corresponding to a product, feel free to query, modify and update data, add and remove variables in the browser-driven modeling and drawing the corresponding products. Since MDT inhibition variables can be built in 4.0 has added auto-inhibition of zero-length parameters drive size function, so that differences in the fine structure of parametric modeling of products more convenient.
4, through the output and input
other file formats file formats, such as through other: 3DS, WMF and other output and input. Select the output ... released, they can use Web browsers such as Netscape.IE, can also be used to provide plug-in module Autodesk WHIP! so open. DWF format only output available commands invalid, or format file output settings, print, select the setting output. AutoCAD files through the slides (. SLD), can be inserted into the graphics data in the desktop publishing system can also be used with the Script command group file (. SCR) in the system by order fast display graphics, can also be used to make your own dialog box file (. DCL) graphics tips. by Note: In the model space, only the current window graphics made from a slide in the paper space will be all the paper space window graphics window and made a slide; in the slide is not included Graphics are not part of the screen and the layer is closed or frozen; production should make possible high-resolution display.
II software built directly on the synthesis of other documents
1, reference to other software AutoCAD, MDT Software's default background information is generally white, and AutoCAD's default background is black, was built in the synthesis of other software documentation, AutoCAD should first read the white background, in the ; dialog box location, size, should be removed after the border, to prevent the black border printed graphics, the general software is selected in the right of the object in the corresponding pop-up menu operation.
2, in AutoCAD, MDT referenced raster image information in AutoCAD the input of the raster image, use .. Raster files can not be deleted, or or printing; can not use ADI or non-Windows-driven printer driver, you must use Windows system printer, do not respond to , to consider adopting a more comprehensive approach for. To address some other software to print the size of raster images. not easy to adjust the location of such defects, the use of AutoCAD printing of raster images, raster image input, print on paper to meet the direct a size, product quality or product description, vector drawing software, more powerful tagging functionality that vector mixed raster file to be built, but the raster vector hybrid editing software such as GTX, AutoCAD Overlay is a more professional software, each needs the million RMB is not usually an individual or occasional user, who can buy. The following raster vector hybrid construction using AutoCAD files. raster image into the post, first aid should draw the appropriate line, raster images and vector graphics adjust the relative position and size, as with ensure that the image will not accidentally click on the selected and moved, and to avoid the border print and display, can also be with the the perspective of a number of products, the product can be the first photos with a digital camera or scanner into a raster image scan into, and sometimes need a few images with, to build raster vector hybrid file, draw a good corresponding auxiliary line, remove the raster image, angle can be measured or marked. as long as raster images into a plane is not inclined to ensure that, in the painting guides carefully. seriously, measurement accuracy can meet the general engineering applications, and sometimes to score the first measurement of the precise degree.
bring Autocad drawing function, I do not think anyone would not extend the thumb, in practice, we can not just use the CAD, vector, and sometimes relate to various software, such as using Photoshop make color pictures illustrated instructions make use of Word, but the software itself has no convenient CAD drawing of how the software can perfectly compensate for the shortcomings of each, so that each software can play the greatest advantage? This comes to the software data exchange problem, Now I put some of their practical experience in the past few years to write, and hope to initiate.
First we have to clear two basic concepts:
1. the difference between bitmap and vector:
Autocad belong in the vector graphics (and Coreldraw, Freehand, Flash, like the software) in Figure 1, simply, the biggest feature is the vector of the graphics to enlarge both the number of times, will not affect the graphics clarity. and processed images in Photoshop is Zhiwei map, bitmap clarity and resolution of the image itself, and if the printed image is too big, of course, pictures will be blurry, because within the unit area pixel reduced, although Photoshop can use this type of software to increase inter-pixel interpolation points, but after all, and the original image pixels can not be compared, a greater discrepancy can only be said to be drawing as much as possible to improve the quality of Bale.
CAD and Photoshop software, so data exchange in the final analysis is the vector and bitmap conversion between the.
2. Postscript and TrueType fonts:
start from AutocadR14, CAD support for Postscript and TrueType fonts, and these two fonts are vector fonts are filled area, Word is using such software TrueType fonts, then why have two vector fonts do?
Postscript is a vector of early Chinese characters, it is for the first Mac, PC, at that time only in terms of dealing with graphics is mentally handicapped, then Microsoft launched its own TrueType fonts, and now Word, Excel, etc. are used to this, although these two beautiful text font, But you have to spend a lot of the cost, because of their weight in the CAD drawing and re-generated in the time gap and therefore does not encourage people to use CAD in this font, and use a built-called. shx font formats it shows much faster pace, but there is no appearance in front of two fonts, if you want to use in CAD in the Word of the graphics (such as real estate advertisements in the plan) then I suggest the best graphics in the CAD The small Chinese TrueType font with, so there will not be garbled, or when the time anxious sweat can not say I did not warn you yo!
understand the above principles, we will talk about how to achieve Autocad Word or Photoshop graphics and data exchange of such software.
one CAD graphic directly into the bitmap function
CAD starting from the third edition provides a bitmap insertion, the method is to select insert> raster After the image, this time into the picture appears a dialog box, click Attach button, then click Browse, find the picture from the hard disk location, then the bitmap transferred to OK, insert text must pay attention to the choice of fonts, or there may be inserted into the text the wrong place, such as horizontally into a vertical arrangement, you can use some of the more common fonts. If you want to download pictures you can click the Detach can, of course, changed the path of image Remember also to update by clicking Rload yo. and then to mention that this is really just a picture into a link, the picture is not really in the CAD diagram, if you want to copy it, in addition to copies of Dwg map Also remember that picture Yeah, the other into the picture has a frame, but the print is not, do not worry.
Second, the use of OLE function paste Dafa
If you think a way to effortlessly above, we can Windows version of the software using any accurate way to test, sticky paste directly, because almost all of the Windows version of the software support for OLE functions. TrueType fonts, but font is best to avoid unnecessary trouble. CAD in our Command under the command behavior of the empty out of the window with the mouse, so you want to paste the graphics in the window of which (with Crossing window options are also available), then see the graphic appears on a number of landmarks in blue (indicating the graphics has been selected) shown in Figure 2, click Editrcopy, then open the appropriate software such as Word, in Word, click dark! Do not worry, this is because the work of our CAD interface is black, into the CAD election ToolsrPreferencesrDisplay Color options selected, then click in the Graphics Window midpoint, and then click on the right of the white box, click OK to exit, and then Repeat, how, grinned it. the Word into the CAD in the Chinese version can also be used this way, attention is best to paste the author recommends using EditrSpecial paste this one. I also encountered a situation that is a bitmap clearly in the above, but the plotter to draw when it was not painted, but you can play the text, this feature can be used to resolve referenced images, I think it might happen and drawing machine drivers. Although this method fast, but the effect is not inserted picture is not clear, especially if the zoom is not even read, so it is still best to use the former method, if like me your eyes and very picky.
III CAD in the vector into a bitmap
AutocadR14 provides the function of the bitmap vector conversion. In Command: enter the Plot command, there will be a drawing of the dialog box, what? no! haste to, enter Cmddia , the system variables <0> to 1. (from the command line to form the menu), then we find that Device and default information (equipment and default information) in a column is Windows98 printer, see We come to the plot device of some settings, do the following to me, that was the key yo. Select ToolsrPreferences option, enter the Printer Settings screen, click New, there were many output devices, select Restarfile export ADI 4.3 - by Autodesk. Inc, you can see in the Add a description can be descriptive text, and press enter, then there will be a lot of options (see Figure 3).
Supported models: (Select the output resolution image rate, if you want to set their own can choose 11)
1. 320 x 200 (CGA / MCGA Color)
9. 1152 x 900 (Sun standard)
10. 1600 x 1280 (Sun hi- res)
11. User-defined
Enter selection, 1 to 11 <1>: 9
You can export the drawing in any of the following raster file
formats. Please select the format you prefer.
1. Microsoft Windows Device-independent Bitmap (. BMP) (to generate Bmp graphic file extension, the following options are similar, the authors suggested the use of Tiff format)
2. TrueVision TGA Format
3. Z-Soft PCX Format
4. TIFF (Tag Image File Format)
Enter selection, 1 to 4 <1>: 4
The export file can be created as a monochrome or color image. (Select the output image color spaces available
default)
1. Monochrome
2. Color - 16 colors
3. Color - 256 colors
Enter selection, 1 to 3 < 3>: 3
You can specify the background color to be any of AutoCAD's 256 standardcolors. The
default of 0 selects a black screen background.
Enter selection, 0 to 255 <0> (select the graphic background color, default is black)
Sizes are in Inches and the style is landscape
Plot origin is at (0.00,0.00)
Plotting area is 1024.00 wide by 768.00 high (MAX size)
Plot is NOT rotated
Hidden lines will NOT be removed
Plot will be scaled to fit available area
Do you want to change anything? (No / Yes / File) :
as would like to modify the above parameters can be input Y, otherwise N.
completed with the above settings, we will see the equipment in the Plot dialog box can choose the device field, behind the work like a map with a drawing machine Like, not nonsense. If you want to modify can click Modify, then select Reconfig reconfigure on it.
four to Postscript output bitmap raster format fully meet the customers this way
precision images output requirements, conducted more conducive to late finishing Photoshop, but the amount of data to be shocking, there twenty-three Shizhao casual file. It's kind of configuration methods and the like (see Figure 4) in the device options selected Postscript device ADI 4.3 n by Autodesk. IncSupported models:
1.300 dpi
2.600 dpi
3.1270 dpi
4.2540 dpi
Enter selection, 1 to 4 <1> : 2
Do you want color output? whether to color output
Some Postscript devices require a special ^ Z (control-Z) character
at the end of the file.
Do you wish to append a ^ Z? is set to Ctrl-Z end of file marker
Adobe recommends that a special ^ D (control-D) character be added
at the end of the file if the Adobe Standard Protocol is used.
Do you wish to append a ^ D?
If you have a roll-fed plotter with Level 2 Postscript you may want
to limit the paper used to the selected ACAD paper size.
Do you wish to limit the paper used? y whether to limit the paper size
Specify port: (selected output port, taken not to conflict with the mouse etc)
< ; S> erial port (Local).

arallel port (Local).
etwork port.
What is your Postscript device connected to?
Do you wish to change the serial port communication parameters?
Do you wish to change the serial port communication parameters?
Enter serial port name for plotter or. for none : PLT1
Do you want to respecify the port?
after completing all the settings in the Print dialog box, select the column in the device to connect the output to Eps for the extension of the picture, in the into Photoshop will ask you to call about the resolution of graphics in general is set to 150dpi is enough, too much hum of your machine will not work on, the line width can also be carried out in the graph parameter setting, but do not become too thick a piece of the black death.
five bitmaps into vector CAD-
how to convert bitmap known CAD, the amount of map to help us re-editing is Many people dream of things, although there are other such software, such as Vpmax, but the actual effect is not good with it. I'm here to tell you a good idea to use the aforesaid method in CAD in the redeployment of bitmaps, zoom to the right proportions, then the command described CAD, although the fees, harder, but compared to direct the drawing up and I do not know how many provincial King ah!
described the day I finished in three A1 drawings yo, income can be Yeah quite good, so we do not underestimate this method. As to how the map scanned into the computer I will not say, figure big sweep can be folded up several times, and then the stitching in Photoshop, if you still have some good way to tell me yo.
divided by the sense of some other, CAD also provides many kinds of data formats such as DXF, 3DS, DXB, etc., they all correspond to different packages such as 3DS, 3Dmax, etc. Now out of 3D studio VIZ is Dwg map can be called directly, indeed solve the data conversion process in a variety of reasons the problems arising from information loss. I would also like to say that although the point is that with CAD are vector Coreldraw However, there is no difference between them can not, such as Coreldraw8.0 can mix CADR12 version of Dwg map, does not support R14 version of the graphics, so it also needs to support the function of packages, after all, not a company thing Well produced . I think the only fully understand this software and data conversion software, you can better use the advantages of each software package, to make better work. in practice, everyone would like to try as long as I'm sure will be a good way to find out more.
1946 on the birth of the world's first computer. For half a century, with the rapid development of electronic technology and the rapid popularization of the Internet, the computer in its operation speed, high accuracy, with the memory and logic capacity, capable of automatic control and other functions, in people's work and life, playing an increasingly important role as an indispensable component.
in urban planning and management work, along with the application of computer technology, planning workers who are gradually emerging from the drawing board and a ruler, paper-based office block toward the direction.
1995 visionary leadership of the Urban Planning Bureau, the investment dozen dollars to buy high-performance computers, digitizers, plotters and other hardware devices and the Chinese characters developed MAPGIS geological mapping system software, and the organization of personnel training and study, and began trying to office automation.
After three years of deliberation, in November 1998, with the City Urban Planning Geographic Information Center was established, also sounded the City Planning Office Automation overall advance of the horn. by virtue of its advanced information center hardware, high-quality personnel, and City Planning Bureau and the China University of Geosciences MAPGIS jointly developed urban planning and management office automation systems and other advantages, and undertake maintenance of the Planning Bureau office automation system (to achieve graphics, images, text, tables and other synchronous transfer) of the task.
MAPGIS urban planning and management to achieve office automation, must the other two conditions, namely digital topographic map of the city and the superposition of urban road network.
Currently, the city has been digitized topographic maps 50 square kilometers, the data format used in all MAPGIS management, namely WT documents, WL documents, WP files, WN documents and WB document, it represents the type of cloth for carrying baby were points (PNT), line (LIN), Region (REG), Network (NET) and table records.
MAPGIS system with its irregular lines and characters on the handling and expression, and powerful library functions into the operating system in the management of the first topographic map. However, Friends of the background of the digital topographic map, use the edit function MAPGIS planning, design and management, it looks bloated.
City planning, design and management requirements of software services have the necessary functions, including as to accurately capture, extend, trim, fillet and query data, etc., but MAPGIS editing system is not easy maneuverability on the mapping.
country now widely foreign engineers and technical staff to use graphics software AutoCAD (Auto Computer Aided Design), is the United States since 1982 AutoDESK company then launched a general computer-aided drafting and design packages. more than a decade, constantly updated version, after the fifth momentous changes, increasingly enhanced functionality and perfection.
AutoCAD is not only draw a single line (wireless wide, Line), drawing two-dimensional polyline (Pline), to accurately capture (Snap), extension (Extend), pruning (Trim), Fillet (Fillet), mirroring (Mirror), stretch (Stretch), and query (Inquiry) and other unique features, and its operation; tolerance (not easy for non-standard operation and crash) and provides a variety of use interface technology (AutoCAD in order to achieve ...
