Have anyone of you guys using this?

Maybe a lot less tedious than counting squares, if reliable.

That and the one I use I find gets me within 10% of being what I see on a dyno when all is said and done.

A lot of paint programs (Photoshop,etc) can do what this does.

Looks like a nice program to use though.

Yeah it's amazing what can be done with basic computer skills and even with a simple spread sheet. I know because I can't do it and when someone does I am amazed. :)

Old drafting/engineering trick:

Make your sketches or make an actual cutout of the cross-section.

Weigh the cutout.

No computer required
