I know it is possible, but I don't know the methodology. My customer has a logo that he wants silkscreened on his pcb. What is the method to do this? What format do I need him to provide me, and what do I create from it? A bsm?Got to go turn the burgers now........
There many ways to accomplish this but the one way that works the best for me is DXF Import. Once you imported the DXF file in Allegro you could generate IPF plot files (.plt) that can be loaded back into Allegro to scale the size up or down as desired or even change layers. In some cases you may be able to convert closed polygons into filled shapes to reduce the elements that make up the logo. When I was not able to get a DXF file of the logo or somehow unable to import it into AutoCAD to generate a DXF file I would use some Freeware programs to convert image files into DXF so they can be loaded. Here is a couple freeware programs that I have used in the past.WinTopo Freewarehttp://homepage.ntlworld.com/softsoft/wintopo/wintopo-free.htmRaster (BMP) to Allegro (IPF) = Access to Cadence Sourcelink required - Program is "As Is" and not supported by Cadence.http://sourcelink.cadence.com/docs/db/kdb/2005/Feb/11022718.htmlHope this helps,Mike CatramboneUTStarcom, Inc.
I've got an adobe illustrator file that I converted to dxf. When I try tio import it into Allegro, only a couple of pieces show up. But if I view the dxf in Illustrator or Autocad, it is fine. What am I doing wrong??
Hi,Find the procedure to import .BMP/JPEG/.JPE/.JFIF/.GIF/.TIF/.TIFF/.PNG/.DIB file to Allegro or PADS layout:Uses:1.When the customer provided the logo or drawing in bitmap(or Above any format) format.Without creating manually ,can be imported directly to the layout.2.When the customer not given logo and asked us to down load it from the web. Down load the logo and convert it into any above mentioned format and import the same into the layout.Procedure to import the .BMP/.JPEG//.JPE/.JFIF/.GIF/.TIF/.TIFF/.PNG/.DIB format file to PADS layout:1.Save the above file in monochrome .bmp format.2.Copy the script file BMP2ASC file in the same directory.3.Run the command BMP2ASC bitmap.bmp ascii.asc 2 26 0 0 at DOS command prompt.Where BMP2ASC is the script file name. bitmap.bmp is the bit map file name ascii.asc is the converted output in .asc format.This command will scan the data and convert it to horizontal lines 2 mils wide. These lines will be placed on layer 26 (silk-screen top), and the lower left-hand corner of the image will be at 0,0.(w.r.t.,PADS Layout).4. Open up a new PADs file, and import the ASC file. Be sure to set the color and the minimum displayProcedure to import the .BMP/.JPEG//.JPE/.JFIF/.GIF/.TIF/.TIFF/.PNG/.DIB format file to ALLEGRO layout:1.Save the above file in monochrome .bmp format.2.Copy the script file BMP2ASC and .bmp file in the same directory.3.Run the command BMP2ASC bitmap.bmp ascii.asc 2 26 0 0 at DOS command prompt.Where BMP2ASC is the script file name. bitmap.bmp is the bit map file name ascii.asc is the converted output in .asc format.4.Import the .asc file to allegro board file. OR5.Import it to PADS layout.Export DXF of the same.6. Open up a Allegro file, and import the DXF file.script file BMP2ASC is available under web.I hope problem is solved.Regards,SATYA SHANKAR.G
Well, I still have problems. I downloaded the bmp2asc, created a bmp from the original logo and ran the exe. I got an asc file that I tried to load into Pads 4 and it does not show up. Am I missing something? This all sounds pretty straight forward, but I can't get it to work.
When you generate a DXF File from Adobe Illustrator it is best to select the lowest AutoCAD version that can be outputted to avoid any conversion issues going into Allegro. I start at nothing higher than AutoCAD DXF 14.0 and work my down until I can get it loaded but normally the AutoCAD DXF 14.0 works. Another trick that I would try is to load the DXF into AutoCAD and explode any blocks that are present because sometimes nested blocks or block elements inside of a DXF file can cause import problems although it is pretty rare.What type of DXF errors are you seeing during import into Allegro?What version of Allegro are you using?Mike CatramboneUTStarcom, Inc.
I'm using version 15. The errors in the dxf are "ignoring spline and hatch which is not suported " So only a portion can be imported.I exported from Illustrator for Autocad 2000. I'll try a lower level.
I tried the version for Autocad 14 and then for the lowest available, same problem.
Have you converted .bmp file in monochrome .bmp (Black and white) format? procedure is open MS-paint ----file+save as +select monochrome bitmap and save it.Then follow the above steps.Could you check once?Regards,SATYAATS ECAD Tech Pvt ltd.
Yes I did convert to B&W bitmap. Still a problem. I think it is the way the original design was made in Illustrator. I can export dxf and read it back into Illustrator with no problems and also with Autocad with no problems. If I try to load it into Paintshop Pro or Allegro, they both fail the same way. Seems like there are different "flavors" of dxf.........
I have had some isolated issues when loading a DXF file into Allegro and I started out with an Adobe Illustrator file which I converted to DXF. In these cases I would load the DXF into AutoCAD and explode elements that Allegro was complaining about then regenerate the DXF file from AutoCAD. After a couple times I was able to get a usable DXF that could be loaded into Allegro.If you are allowed to distribute the logo you are trying to import please attach it to this thread and I am willing to give it a try for you to see if I can have better luck.Mike CatramboneUTStarcom, Inc.
Hi Pitbull,If it's ok, send me the logo, and I'll give it a run. I've done this a few times, and it's normally trial-n-error. Might be something simple. I'll try it if I have the file.Mitchmailto: email@example.com
Have you looked into PCR 11022718 over the sourcelink?Did you try the "Raster to Allegro" ???More details at:http://sourcelink.cadence.com/en/search/DisplayHtmlDoc.jhtml;jsessionidsl=1SNF2JAX0DCWDLA0BEASFEQ?param1=http://sourcelink.cadence.com/docs/db/kdb/2005/Feb/11022718.html?param2=null?param3=Solutions?param4=11022718?param5=/software/cadence/sldocs/db/kdb/2005/Feb/11022718.html@en_col?param7=How%20to%20import%20a%20bitmap%20file%20(BMP)%20into%20Allegro%20PCB%20EditorBest Regards,Kishore
