One of the problems with CAD system is that now you can design things that are very complex and compound curves are trivial to make so you used them and then you start worrying about of a sharp edge should be broken with a 1mm or a 1.5mm radius. Because your two inch long part is being displayed on a 26" LCD monitor you see tiny little things and fix them. The problem is an over-designed part. It is easy to do. Generally, this is not harmful except you waste time.
But the other side of this is that now you CAN design parts that are impossibly hard to hand code. Compound, organic looking curves are just as easy as geometric shapes so "why not". You parts don't have to have thar "home shop" look to them. On Wed, Dec 19, 2018 at 11:20 AM John Dammeyer <[email protected]> wrote: > > Computer CAD is something like that.
