I got to playing with the Solid Edge program.
Here's a model of the Brodak .25 crankcase.
It took around two hours to accomplish.
The program will also provide all physical parameters - CG, radius of gyration, three axis moment of inertia and weight. I need only enter the specific gravity of the material.
Really fun!!!!

Bob,
Did you have to draw the Three Views?

Biob,
great rendering. I drew my FP 40 in 3d as well but in Autocad. I dont have solid edge but hear its actually much better for rendering 3d,, well duh thats what it was designed for. are you going to render the innards too? In fact, the initial layout for my 109 stunter was done in 3d so I could get a feel for the proportions and forcast the overall effect. I enjoy working in 3d but in autocad its a bit cumbersome. I hope to get solid works, or Inventor so I can explore 3d modeling a bit more in depth.
keep playin its fun to see what you can do!

I used a linux version of Inventor. Pretty cool.

With these sophisticated modeling programs, you might be able to calculate the 2/4 break!
Great stuff, I wish we could get it for about $99.95..

Hi, Gents. Good questions.
Solid Edge is parametrically driven. When you open a new drawing, it defaults to three intersecting planes. To create the first feature, you pick a plane and extrude from it. For a cylinder, you draw a circle, assign a diameter and length. That can serve as the engine cylinder centerline.
Then, extrude another cylinder from a perpendicular plane and you have a crankshaft C/L.
Continuing, you just keep adding features - bore, exhaust port, bolt holes, fins, intake and so on. If something needs to be at an angle, you just create an angled plane and extrude the feature from that.
The program runs under windows and is the most user friendly modelling program I've ever used.
Mark - all the innards are indeed rendered.

Do you have a good source for the software the only reasonable price I found required a student or teacher ID.

Has anyone used Turbocad, is it easy to use? I'm looking for some software to draw rib shapes( can't draw anymore-inherited tremor). I tried using Paint on our computer ,but not very useful.
Thanks
Steve

Sounds like a hopped up version of Google Sketchup. More likely the other way around.
The Google Sketchup is absolutly free for those who want to play with it.

Bout time we got some serious cad happening again. You see this stuff all the time on the RC Universe sight,(They are phenomenally good). I used SolidWorks for a time, but got away from it because it is not as readily adaptible to laser cutting as DWG. Solid Edge is generally considered to be the easiest parametric modeler to use because it is designed specifically to transition you from Autocad 2D. That has been there main Marketing strategy. If I were going to attempt a stunt engine today, I would use Solidedge\Solidworks for the modeler and use rapid prototyping to get my initial parts. I would then get my g code parts off that.
