The scanner I use is a quite reasonably priced HP "Scanjet 4670". Less than $200. I can pick up the scanner unit and place it anywhere on any size drawing I want, do a one button scan, move the scanner over, do another scan and so on. This way I can scan a drawing of any size and then use imaging software to splice all the scans together. If I want to take the time. Probably takes half an hour to scan and stitch a typical d size sheet. That's why we farm out all our big scans to various local and not so local scanning services. One other thing about the demo version of Deltacad: To keep using it after the 30 day trial period, just re-load it. I extended my "trial period" to over a year. Screw that. I want his flatbed scanner! :-) Russell Kent -- John Kimmel I think it will be quiet around here now. So long. And we gonna piece the print outs together with taps? I guess I'll stick with my old Epson FX's. |

I've done drawings 13 feet long and 5 feet wide that way (these are Sikorsky S-64 parts). I can use Deltacad to adjust the scale of the image in x and y directions to get within .020 across a 12 foot drawing, but I have to use an image editor to take any warpage, skew etc. out of the image. Once I get a usable 2d vector drawing, I can import it into a modeling program and design tooling, flat patterns, 3d parts, etc. Deltacad works much better than the automatic vectorizing program I was using before. Another thing I really like about Deltacad is the great flexibility and ease of printing drawings on a large format plotter (or any printer for that matter). The Oshkosh satellite photo posted here a couple weeks ago happened to be a really high resolution image. I copied it into Deltacad and printed it out on 42" wide photo paper. It looks really nice thumb tacked to the wall. I used the demo version for about a year before I sprung $50 for the non-watermark version. For me, Deltacad is the ultimate tracing paper. -- John Kimmel I think it will be quiet around here now. So long. I WANT YOUR PRINTER ! Printing large format can be difficult. I drew the wing rib profiles of the Dyke Delta (each one is different) and took them down to the local CopyMax. It was to big and they couldn't handle it. First of all, it had to be in PDF format and then it just locked up thier computer. We finally figured out that we could print it half-size on one of their printers and then use one of there automatic enlargers to get it to the proper size. The printout was 8ftx4ft. -- http://www.ernest.isa-geek.org/ "Ignorance is mankinds normal state, alleviated by information and experience." Veeduber |

Got a call the other night from a total stranger .... He's trying to track down some tracing paper. http://www.artsupply.com/alvin/tracing.htm Architects use it by the running yard, at least those of the old school. Sometimes it's easier to think with a pencil than with a CAD program when doing preliminary sketches. Waxed paper makes great tracing paper but nowadays most folks don't carry those narrow-lead wax pencils you need to write on the stuff. Usually referred to these days as "Film pencils" or "Mylar pencils". Try colored leads for a mechanical pencil. You trace on the less waxy side. Truth is, I haven't used real tracing paper since the late 1950's when it was replaced by frosted acetate and later by frosted Mylar. Mylar gets a bit spendy, and Acetate is worse. The non-frosted stuff can be marked with a Sharpie. The frosted stuff (a starch coating gets put on it) can take pencil or pen. http://www.artsuppliesonline.com/cat...m?cata_id=4984 Another way to transfer plans is to use Dressmakers Carbon and a tracing wheel. Transfer directly onto whatever you're going to use, either for a pattern, a jig, or a part. |

"Joe Maj" wrote in message om... (Veeduber) wrote in message ... Got a call the other night from a total stranger who identified himself as a fellow resident of northern San Diego county and a homebuilder, too, although he lives up near the Pala Indian reservation which puts him even farther out in the sticks than me. He's trying to track down some tracing paper. I went to the local Michaels craft store and bought a 50 sheet pad of Strathmore tracing paper (11X14") for about $6. Look in the art supplies section. We used mylar from the art supply stores. While building Murphy Renegades we traced parts like ribs and gussets onto the mylar, then cut the mylar to size and shape, then traced the mylar piece directly onto .125" or .063" aircraft aluminum, or as the case might be. Then over to the band saw, then to the sanding belt and files for deburring, then to the drill press. Then to the alodine vats. And so on. If the piece needed bending, we had a brake for the purpose. |
