Interesting about the Gif. The full size jpeg's are 250k and 530 k files. If they become Gif.s is there a way to make them available here on the forum rather than as an email attachment to Chinese? I have to admit ignorance about the abilities of Gifs and would really preffer mounting the full scale file here so all can share. I will export them to GIF. They are currently Corel vector files and only about 35k but not everyone has Corel or the original program they are created in, Auto Cad.

The Gif of the 530 k jpeg is 145k.

Gif is a non-lossy format, and given the nature of your drawing, you should be able to save out a 1-bit (ie B&W) gif... i grabbed one of your patterns which was 48 k as a jpg... removed the noise (which unfortunatly also means a bit of detail loss on the edges (which would not occur if you start from the vector-artwork). I ended up with a 13k file at 2 bits (necessary because it started out as a jpg) but a 1 bit file was ~10k. So not only is it smaller, the quality will be better (if not passed thru jpg)

I can help you work thru this, i can read & write an aweful lot of formats. I'll send you an email so you can attach a sample dwg and we can see what can be accomplished)

hi there, sorry to hijack the thread, but BudP, if you're doing it in ACAD you can automatically "print" to desired Bitmap format (try for instance .Tif) and then in photoshop or similar to .gif like planet10 said.

regards and chinese by the way, congrats on your design!!

Bruno H.

ps. you've got to add a printer in autocad for "raster file formats", you do have Jpg and tif as well already there!
 
Chinese,

I have the cone pattern placed on an A4 letter size sheet of paper, 216 mm wide X 280 mm long, except it is 25 mm longer, so you will need to set your printer for 305 mm and hand cut a piece of paper. I cannot send this GIF file to you through this forum, and cannot mount it as an attachment as it is too large at 145 kb.

Can you send me an email so I may return the file to your email address. I will not pass this email out to spam makers or to other people.

Carcass,

Thank you for your comments. I do use the Auto Cad rasterize for some bit maps and have used it for very high quality Tiff's from 3d solids machine designs for assembly instruction manuals and the like. In this case I need to use Corel as an intermediate step so that I can scale and stretch the conic section cut out to exactly fit the cones in question as some will be applied to the normal front and some to the normal back.

I have not produced templates like this before, having always used a calligraphy pen to apply the blocks. In another thread we are working on actual templates, made from sunlight exposed photo resist coated silkscreen material, that appears to have the properties needed for applying the pattern with a foam brush and using the silkscreen, with appropriate holes opened in the coating, as a mask.

If this works as expected it will open up many different finished drivers to treatment with the EnABL process.

Chinese,

You should contact the moderator for this thread and ask him to remove your email address. Spam providers are always looking through forum sites for free emails. I would do it soon, unless you can still edit your posting.
