Excellent tutorial! A little reverse orthographic projection!

i don't know what eddy is talking about, with them $10 words (maybe he will let us dummy's in on the meaning)
but i thank you for the effort, i have tried several times to explain the alignment lines
anybody with some graphic program experience can copy and paste 2 pictures into a single image, but making the image features align in simulator elevations is a tough thing to explain, you did it for me,

thanks for sharing experience and the patterns you have. although i may not use them, they do provoke thoughts of other projects that could be done in the style....

Thomp.... Don't pay no attention to me. I'm senile! Ha! Ha! I was just commenting that Orthographic projection is in drafting the conversion of a 3D-object to a 2D-object. This thread is just the opposite but it's really just an old time drafting exercise. I'm not even sure that our young computer geeks even worry about it anymore since the new AutoCad programs work in a 3D-enviroment. Personally, after they took my pencils and paper away from me I was lost in a 3D. That's one reason why I still have AutoCad Version 14 on my computer.

oh,
close to an autocad program ive used here lately is sketchup by google, but being so old in mind, im lost in the instructions to use it

i would love to have a program where you could do some autocad programming without it over running the computer resources and locking up.
oh well.

i can draw about anything i want, then photograph it, and play with the size till i get what i want, its laborious but it works.

Huge Grin!!!

I admit it - I'm old fashion when it comes to working patterns. I can use auto cad programs and have. But over and over again I return to three simple tools - paper, pencil and eraser.

I realize that everyone on the message board knows how to use a computer and many regularly use some very fancy, high powered graphics programs. But that's not true for everyone. There actually are people out there that still are novices to computer use, especially graphics programs. So I still chose to teach the "old fashioned methods" because they are tried and true.

You should see the reactions I get when I teach the grid method of enlarging designs or the string and push pin method of circle making. And when I suggest that you just turn your pattern paper to the back and rub pencil all over it to make carbon paper there are actual gasps!

Another huge grin!!! I guess I'm teaching the AARP method of wood carving ... Oh, snicker - my age is showing.

im with you susan,
nothing wrong with the aarp method, heck most of us wouldn't be carvers unless we held jobs sometime in our lives that were so boring, i spent many years on swing and graveyard shift monitoring gages and electrical pumps,. and couldn't leave the immediate area,
not interested in much reading material i started carving, helmets on jungle boots for the vietnam vets retiring from my branch as a token of appreciation, as uncle sam surely wasn't giving them much for there service through them years, folks put them on there desk at work or in the barracks, and re-furd to them as short!
boots had strings with a Cegrams VO ribbon tied on the first lace bar and a small bottle of the G.I. green repellent in the hat band,

painted with left over paint by number oils..
but most patterns were done on paper and pencil and pencil carbon used as carbon paper on the back of the pattern
it works in a tight and heck your only transferring a likeness... of the original thats gonna get carved off any way.

Common since is something you gain through your experiences that went right... i think...

Thanks for the very well described and useful tutorial. This method was taught to me some years ago and I've used it to transfer drawings as well as images of solid objects to paper.

One aspect that I didn't catch in your description that I have found useful is to establish a center line in the view(s) being created. This allows using a straight edge and/or right triangle to keep lines from wandering. It also provides another place for measurements.

FlyFisher .. Excellent point and and excellent addition to this little tutorial.

Thank you, Susan

As a card carrying member of the AARP carving set I just wanted to let you know Susan that I wasn't advocating autocad over pencil. In fact, after you posted your thread I sat down and worked out a side view for a project that I was working on, and I did it with pencil and paper. The human hand and brain may be slower but they can work circles around a computer! And again, great tutorial!
