Hey people,

While lurking in this area, I have read some warning posts about posting G-code for parts. I assume this is mainly because of people might use this code for part duplication thus violation of copyrights.

I think some of us here like to CAD our parts for record keeping and documentation purposes, a CAD drawing contains only information on diamension only. Is this okay to post the drawing of part with diamensions ?

When you buy the part, you own the part and you can measure it anytime in anyway you want. You might not allow to re-engineering or to replicate it but posting the measurements should be okay, right ?

No one can stop you from posting G Code for parts. It is only a bone of contention if you reverse engineer something and then try to sell it, especially if it is a blatant copy of something with a legitimate copyright or patent. Even then it would take lawyers and the like to stop it if you could.

If you want to go to the trouble of measuring and drawing parts and then posting them. It is OK with me.

terry is right as long as you dont reproduce it to sell i think there would be nothing they can do about it since anyone who knows how to use measuring equipment can dimension it. what are they going to do come take away our calipers? LOL

I work in reverse engineering of real turbine parts, and unless the design is patented or has some feature that is patented you are ok.

People reverse engineer components all the time. We try to make improvements to the design whether it is dimensional, materials, processing or performance, through analysis that is as good or better than the OEM. The OEMs are not necessarily interested in building the best product, they "Build in Obsolescence" or build in degradation so they can sell replacement parts. There is a market for small business like mine to build the best damm product and sell it. I don't care about making billions of dollars, but we can make millions selling better components and not care about having to sell replacement parts in the future. The market is so big, who cares.

My advice if you don't want to get into investigating whether the designs are patented or want to stay out of potential trouble, is to use the OEM design for the "attachement" or other features that mate up to other components and modify everything else slightly.

Light travels faster than sound, thats why some people appear so bright UNTIL you hear them speak.
