The Truth about Reverse Engineering

Most videos don't go into detail about what it takes to reverse engineer a somewhat complex part. In this video, we show you in 5 minutes the 3-hour workflow to 3D scan and reverse engineer a sand cast part.

Yeah man. When my company first started reverse engineering from scans, there was not a lot of content out there. The salesmen promised amazing accuracy and the pros reported even better tolerances... But it took me a long time to realize it's more of an art. And there is a definite difference between being accurate and capturing design intent. Anyone promising a parametric model of an injection-molded part completely within .004" is either a god or a liar.

So glad to see this video,
I have superiors who think you sit down and within some minutes, boom! your Reversed engineered CAD Model is ready...its very challenging, explaining to them that it doesn't work way.

Thanks for setting realistic expectations on what this process entails. 😊

I thought you are gonna talk about some hardware reverse engineering (Hardware security) but nice to see other parts of the world as well

This is most definitely a point that is lost on a number of people. There is, for sure, a skillset in scanning parts properly, and indeed in using other measurement techniques to reerse engineer a part as scanning is not the be all, and end all of data gathering techniques. That all said getting the data is one thing but knowng what to do with that data is completely another.

I've used a CMM arm to reverse engineer parts, but the CMM software set your X, Y and Z planes but I could never get a radius endpoint to touch and be tangent with a straight line on any plane.

Would you please share the scanned cad model. I need to practice it for reverse engineering.
Thank you in advance.

Hahahaha preach on eh. Very accurate time line. Keep on making the honest and helpful videos.

Hello sir, my name is rajan Patel and i am see your video of scan to cad it's really help for me.
Sir want to know how much annual income of reverse engineering designer as a fresher ? Pls. Sir give me the ans. When you show my comments.

[s.sradon]

why not just use calipers and a notepad?
I don't understand why 3d scan when you have to remake the part anyway.

I dont have scanner, my company expect me to reverse engineer plastic parts thats move a lot with 0.01 accuracy, and want it to be in few days without a single error. taking measurement is hard and then they simply check it and moving it around and simply tell this part is 1mm larger, do it again. Their measurement process are also questionable. I took lots of measurement and try to figure the design intent and they simply just said the measurement is incorrect hello.

ITS Only model, can you casting in real
