Case Studies

We were recently tasked with recreating a fan housing using only the client’s original paper drawings.

At first glance, the job looked fairly simple — until we saw the condition of the drawings. Most were decades old, heavily worn, and spread across multiple sectional views. The fan housing itself featured complex, twisted curves that were anything but straightforward. It was the kind of geometry that modern 3D CAD systems handle well, but the original paper-era documentation didn’t translate easily into digital form.

The project ended up being very similar to the aerospace Mylar conversion work we’ve done in the past — except this time, the part was more industrial than high-tech. Still, the process required the same level of precision and interpretation.

After carefully calibrating and scaling all the scanned drawings, we started extracting the data needed to build a fully parametric, production-ready 3D model. Interpreting the old prints turned out to be the most challenging part. Many of the details were faded, torn, or missing entirely, so we had to cross-reference between drawings to reconstruct missing geometry with confidence.

Thanks to our team’s 40+ years of combined experience in industrial engineering and reverse modeling, we successfully rebuilt the entire fan housing assembly to within ±0.005" accuracy — and delivered it on schedule.
