Auto Cad Question
Hello,
I work in a cabinet shop and have access to a CNC router. My question is; does anyone have a .DXF or .DWG file for a Freedom 7' 9" or a Redbird? I thought it would save me some time building the forms. (It is for my personal project and I would not be using it for any kind of personal gain...except to save myself some time as I don't have much of it to spare these days) If someone has one, I would be willing to send you a few bucks for your time.
Thanks,
POTC

Hello again.
I am noticing that plotting the stations in autocad works OK but to get a nice fair curve from the numbers out of the book I think you will need to use a batten and draw them on paper. I am going to plot out all the points and draw polylines from each point and print them out full scale and then use a thin peice of wood to draw the fair curves and cut them out by hand. I tried smoothing the polylines but it doesn't seem to work out very good. unless you have a better idea.
Thanks
Tim

Electronic Formats?
I also have access to a CNC router and have often considered how easy it would be to cut sections out but the purist in me insists on using a bandsaw! Either way, I also have use of a plotter and could print sections full-scale on paper if a DXF or similar file format were available. To me, receiving a file electronically is preferable to having plans snail-mailed. I'm not sure how property rights would be protected other than the standard "terms of use" agreement and ones own conscience, but is this something that Bear Mountain has ever considered providing?

Re: Auto Cad Question
What are the top CAD software's on the market.? I just want to know what software's I should be looking into studying. I've heard that AutoCAD in going the way of old fashion drafting.

Re: Auto Cad Question
I've built exactly one cedar strip canoe, the Prospector-16. I created the station forms using a CNC router, and was extremely happy I did. To create the profiles, I converted the table of offsets to X-Y coordinates in an Excel Spreadsheet. Once you have these points, I imported them into Autodesk Inventor. One of the options is "create spline". Do this for HALF OF THE PROFILE- meaning one side of the form (think port or starboard side only). Then mirror it to create the other side. After creating the profile, I simply added a rectangle to the bottom, equal to the shear height. Delete (cut, trim, etc.) any interior lines so you only have the outer loop. This profile can then be imported into any CNC machine software that I'm aware of.
Here's the spreadsheet I created. Feel free to use it. It is for a Prospector-16, but it includes directions on how to use it for any design working from the table of offsets. https://docs.google.com/spreadsheets/d/ ... ue&sd=true
