FP,

nice job on your Eyeball. Rainedave and his quick work on plans certainly is an inspiration for anyone with classic pattern tendencies...

As a relative newbie with CAD myself, I found that one easy way to obtain symmetry where required is to work on half the part. Wing and stabs would be an example as would be fuse top views and formers. These are then obtained in full symmetrical draft by duplicating the part and reflecting it on it's common axis (e.g., the fuse or former centerline). Of course it's important to match the axes carefully or else one does end up with assymetry.

In 3D CAD much of this is not an issue as the parts are made symmetric about a specified axis and drafted to precision via software intersection techniques.

What are the specs on your Eyeball? Is that an MVVS 40 engine?

David.
