Hi to all,

I am looking for CAD programs that are suitable for modeling applications , like airfoil and engine designing etc...

Thanks.

I use Compufoil for my wings and Deltacad for the rest. You can download a free copy of Deltacad at www.deltacad.com and a free trial of Compufoil at www.compufoil.com. Hope that helps some. Take care and hope you have a wonderful work week.

In Christ,

This is a very common topic around here. I suggest you try the Search function within this CAD forum with "cad" as the keyword for additional background.

I also use DeltaCad. For $39.95 it is perfect for our balsa / ply toys. I print up fullsize 1:1 dwgs at the local archetech type printer guys and glue the dwg directly to the wood w/ spray77. When it's time to assemble.....wow! the pieces fit like machined parts should. It is not a perfect piece of software compared to ACAD that costs thousands $$$... but it is easy and accurate for 2D work.

I use WinFoil... can't beat the price at less than $50 bucks.

Take a look at my other thread on the DeMilo and you'll see the finished product.

It depends on what you need but Profili2 is free for basic functions and $10 for the whole enchilada.
