      I’m trying to print stations as a pdf but make them full size so I can use them as patterns for station molds. I can print to large size paper that the local printer can handle (ARCHE) but the drawing keeps coming out as though it’s on 8.5 by 11 inch paper. The local print shops can’t handle dfx files and want pdfs. Is there some way to scale this up to actual size other than buying autocad? I did try downloading a free viewer (autocad 360) that was supposed to do this but it doesn’t. I also downloaded a virtual pdf printer (bullzip) but this hasn’t helped.

      This has probably been covered before but I can’t find the topic.

      Thanks

      sounds like your experiencing some bullzip yourself!

      try draft sight. i use it and its very similar to auto cad. it has pdf functions also

      Thanks! I’ve had some trouble downloading Draft Site. I get an error message: error 1320 path too long…

      I just sent an e-mail to them to see if they can help. I hope this will work.

      Thanks again.

      Seems to me that you are not specifying the paper size in the pdf program.

      The other thing is, I normally work in imperial and when I export to DXF/STL, the exported file when loaded into my CAD program is at 1:12. i.e. what is ft in the real world is inches in the DXF file and this requires the CAD file to be re-scaled to match world dimensions.

      Thanks, Bob:

      I am selecting the paper size I want but getting a small image on the giant piece of paper.

      I tried switching the design to metric – same result. Frustrating.

      Thanks again.

      Hi,

      Care to post the file, fbm,dxf,dwg………whatever and maybe we can spot the problem.

      Best Regards

      Here’s the file. It’s a double-ender designed for kids – almost a toy. It’s only eight feet long but I broadened the water plane as much as I could to make it initially stable. A friend of mine saw the drawings and decided he wanted to build one. I’m trying to get full size station molds to make the setup quicker. This was inspired by Flo Mo’s Baby Boat.

      Thanks,

      Sean

      Hi Sean,

      I exported the fbm file to a 2D DXF and yes the size of the import is 1/12 of the full size in my CAD program, (TurboCAD).

      I then re scaled the file by a factor of 12.

      In my CAD program I set up paper space called Bodyplan Aft & Bodyplan Frd at ANSI size E. Mainly because at 1:1 scale the whole bodyplan is too wide to fit the paper.

      I moved and the rescaled sections to form a “Normal” Bodyplan and created views Bodyplan Aft & Bodyplan Frd. These views were placed in paperspaces at a fixed scale of 1:1

      Attached is a zip file of the dxf.

      Hope this helps

      Best Regards
      Bob

      Edit also pdf file on ANSI E paper

      Hi Bob:

      Thanks so much for doing that and sorry to take so long to reply. I was under the weather for a few days and couldn’t get to the copy shop. I had your effort printed out today and it appeared to be perhaps at 50% scale. Sorry to say, it didn’t seem to work. I really appreciate you doing this but it looks like I’ll just have to lay out the stations the old fashioned way. Not the end of the world. It would be nice if Delftship was set up so you could just print full size pdf drawings. It would make building small boats simpler.

      We laid out some stations at the sheer line on an 8 foot piece of plywood and bent a batten around them yesterday. I had some concerns about how tight the curves were aft and they turned out to be too tight for a 1/4 by 3/4 batten, and the aft waterlines weren’t quite fair. I spent a day refining the lines and have bent battens around all the waterlines now and they are quite fair. Tomorrow we plan to lay out the stations. Thanks again.

      Hi Sean,

      Glad your out from under the weather. Isn’t it always the way that it happens over the weekend.

      Weird that the prints came out the way they did but sitting here in Aldinga Beach enjoying the warmer weather……………say la vie.

      Nothing beats a full sized loft to show up errors and I’m happy your project is going ahead.

      Best Regards
      Bob

      With the latest Ver 7.22 I’m having the same issue trying to print full scale pdf for the stations only. 1st method was plot from linesplan with print scale 1:1 but that only prints a single page of the corner of the drawing instead of multiple pages that can be taped together (I also only want the stations and not the whole linesplan) . Also tried using the front view then printing that view but that sizes to fit a single page…I can do a hit & miss on that view with zoom to get close print but yuck. Don’t really want to go the DXF route, just print full size pdfs on multiple sheets.
