(Wow that is one run-on sentence! My wife, the teacher would scold me! )

Thanks for any advice or input!
I have a Comet Cessna 150 Aerobat (29" wingspan, scale 1"=1-1/8') model, fresh in the box, vintage 1975. It is supposedly "True Scale" according to the print on the box, whatever that means. I had never looked at the plans until now; but I see they are printed in both German and English.

Now, for your idea for scaling three-views. IMO, it's an excellent idea, but ...

Keep in mind that the images created from a projection system may not be as accurately rendered (because of distortion of the image) as those you would get from scaling the three-view with a computer program.

While RastaPrint would be an attractive alternative it it were available, there are other alternatives that are much more likely to stand the test of time, e.g., iText, a free Java library for creating and manipulating PDF files.

With iText, the creation of a scaled three-view PDF from a source three-view is very simple:

1. Create a PDF document
2. Add the source image to the PDF document
3. Tile the PDF, if needed
4. Print the tiled PDF

One advantage of this approach is that you can build directly on the tiled plans, once you have taped the parts together. If you destroy them in the process, it is easy to print another set of tiles.

If you're still in Auburn, I can show you how to do all of the above. Otherwise, we could do an example of your C-150 Aerobat via this forum.

RastaPrint IS available. The mass market product is now tentatively called "Arts & Crafts Design Studio" (name pending copyright) and retails $195 in it's introductory version. Ten times more copies sold in the last two days than the RastaPrint version here in a month at 10 bucks

Thanks, Cubber, for that information.

Apparently, Google's search engine hasn't found it yet. Please provide a link.

Best wishes for your success with the new incarnation of RastaPrint.

That'll take a while. So many things to do. Find a software publisher/distributor, print boxes, hire a graphics artists to take care of the product image, etc... that did not prevent me to brew a quick package, consign a couple hundreds of 'early packages' at a large software store in the area, owner's a friend a mine. For now, he's my only sales force, but people react real well when he says "you can call the guy the guy who wrote this... here's his phone number, he lives a 10 minutes drive from here"

Thank you Rick

RP for RC will be back, sometimes not too far away. Will probably be called RP4RC. If everything goes according to plans, RP4RC will generate cutting files for CNC foam cutting machines by the end of this week to come and making airfoiled wing panels. I also have my mind set on laser cutters, and laser cutting services. Everything is being planned to assemble cutting jobs from parts libraries

I take it it is a prog that will tile the pic automatically?

I prefer the bubble canopy P-47 as opposed to the razorback...

Thanks!
Among the many solutions:

1. You can use iText to scale an image (or PDF) to any size needed, rendering same as a PDF file.
2. You can use iText to tile a PDF.
3. There's a nice plan for the P-47 in the current issue of Flying Models.

I've written iText-Java class, ScaleImage, to do the scaling in item 1 above. ScaleAndTileImage does both the scaling in 1 and the tiling in 2 in one run of the program. ScaleAndTilePDF does 1 and 2 above for PDF files.

See thread "ScaleImage ..." in Foamies(Scratchbuilt) for more details.

I think he wanted the single pitot-static system model.

Cubber, I see Fisher-Price is offering a product for kids called "Digital Arts & Crafts Studio". Mighty close to your name. Hope you're able to cash in on it.
