Help, please.

Are there tutorials anywhere on how to take a perspective drawing and reverse engineer it into a set of blueprints?

Any assistance would be appreciated.

Not that I'm aware of. I've done it before but with some difficulty, the trick is to get views from multiple angles. Trying to do it from just one will be very hard, if not impossible.

MisterGorn:

I've reverse engineered firearms components in the manner you are describing. It is possible, however it is exceedingly difficult and time consuming. The major issue is isometric (i.e. perspective) drawings are not necessarily to any particular scale, so even with said isometric, you're still going to need access to either the item itself or someone who can get you dimensions of it.

In one case I was having to have a barrel custom built and the drawing process took over a year. I lucked out in finding someone who was willing to lend me a similar barrel to take measurements off of, whilst the rest of the ambiguities were resolved by annotated photos provided by a friend in the UK.

If you REALLY want to do this, I'll give you what help I can.

Cheers!

Well, I am no doubt biting off more than I can chew, but I nonetheless would like to know how it's done.

The subjects I'm interested in are all fictional, so I'm not stressing about the scale. I'm fine with the "eh, looks right" approach on that variable.

Alright. I've lowered my blast shield. I'm as ready as I'll ever be. Let me have it.

Sorry for the delay, I forgot to check back in here. :oops:

First question, what drawing program are you using? 99% of what I know is geared toward AutoCAD so, while the principles are the same, the mechanics of how to get the program to do it may differ.
