I'm MAD I tell ya, MAD about CAD!.... Well, maybe just MAD.
Well it's been a few years since the Build-a-long post, and over those years I've somewhat streamlined that work-flow of deconstructing a CAD model into cut files, so why not bring things up to date. Since the basics of making a solid CAD model is pretty much covered in the Build-a-long, I won't be going over that so much in this post. We'll be starting this off with a model of a Fiat CR 44, an Italian "paper" fighter/bomber project, although never built, it's a pretty sweet looking machine if you ask me.
So let's have a look at the model dimensions and intentions- 40in. wingspan, 34-7/16in. fuselage, with the wing & fuse being fully sheeted, no bare stringers for this one, and a few 3D printed parts to top it off.
Starting with Fuselage:
The 3-view used for this came from Aerofan magazine #100, and as you'll see in the pics below, there are no fuselage section profiles that I would normally trace and Loft into a Solid Fuselage..... No Problem!
Solid model from surfaces, that's how I'll do it! With the fuse of this airplane being pretty simple, basically a tapered cylinder, a few profile sketches is all it will take.
And as always, this thread is open for any comments, suggestions, whatever, nothing is off-topic here!

( 3-views already placed on the Right-Top-Front Planes, and scaled to size.) Opened a sketch on the Right Plane and Traced the side profile with a spline, using minimal amount of points. The radius at the tail end is split at the center-line. -

Hey guys,
We are now officially started,
so any questions, etc. as we go, just ask here.
When building these CAD models, I don't always follow the rules or proper protocol for 3D modeling, and I like to do things the easy and quick way when possible, so here we go......
Alright, we'll start with some pics for Raipes project:

Raipes Profiles.... looks real good. -

Planes are added from behind the cowl (since it will be plastic) to the end of the fuse. I like to place them at key points, like the start & end of the canopy, and where there's changes in the profiles, such as the tail, wing, etc. -

I ended up splitting the side profile into two, (at the back of the canopy) seperate front & back sketches, because when lofting the fuse sections, the curve of the canopy (in the side profile) will cause a crease in the 3D model when used as a guide -

And the back half of the side profile. Just make sure the belly line of both profiles, front(side) and back(side) are tangent, and either equal or similar curvature. -

Front fuse sections.. the first section (A) is actually a circle, the other two were sketched to match the profile sketches and 3-view. -
Views: 1056
Back sections made the same way as the front, using both top & side profile sketches and 3-view as guides.
Got these pics in an e-mail, all I can say is WOW, just incredible, this guy deserves his work being shown off, period!!! And all the linkages, cables and chains work, just like the real ones, amazing.

Well, finished assembling and maidened her this week, she flies very fast for a small plane (close to 80mph 
) and now I need to get her dolled up with a paint scheme. I'll work with the existing colors and add a few touches, not too much, but as she is, it's just waaay to simple for my tastes.
Did I mention she flies FAST!

A look at the oversized wheels and bent landing gear which are needed to take-off and land from the Club field....can you say bumpy ;) -

A tight fit...... notice the original wheels are quite small, more scale, but just doesn't work for take-offs and landings...nose-over city! -

Here's the scheme I'm thinking of going with, except the silver will be the original gray covering, don't want to re-paint or re-cover her...too much like work :) -
