So I've been using free 2D CAD tool called DraftSight. It is made by Dessault, makers of SolidWorks. The tool reminds me of AutoCAD 2000LT: all needed features, none of the fluff of later AutoCAD versions. The tool is super fast and easy to use.
I am attaching the DWG of the design so far. I am looking for feedback in several areas in particular:
1) how do I mark differentiate between parts that are inside the fuse vs outside or other parts?
2) I am still not sure how I should organize the drawing in layers.
3) This is the most difficult one: how do I show the openning in the fuse for the sidewinder engine. I am worried the nose will not be strong enough.
4) how do I indicate which what material is used for a part. For example all formers are made out of 1/8 birch plywood except for the molded top half formers which are balsa.
5) How do I create cut views? For example, I want to show what crossection of the fuse looks like near the wing.
The design has several aspects that in combination are not common: all inline, flapless, sidewinder using Brodak 40, molded top and bottom all the way to the front, Russian-style keyhole landing gear mount. The model is inspired by Crayola. The goal is to design an expert level model that can fit inside a small aircraft(I fly a Piper Archer). Yes, I could go the easy way and build a take-apart Trivial ImpactoShark but what would be fun in that?
I posted the file in my SkyDrive public folder for everyone to see:
