What is Reverse Engineering CAD?

Reverse Engineering CAD is the act of reproducing a CAD model of a failed or broken part following a detailed examination of how it was originally made. At ProImage 3D we pride ourselves on our ability to re-create, and reproduce models as accurately as possible. Whether we are using our latest high end scanning technology to replicate a part within precision tolerances, or modifying and improving upon an existing design, we will help guide you to the solution that best fits your needs. There are basically 3 types of reverse engineering…

Reverse Engineering for Design Intent

If your purpose of reverse engineering is for design intent, then the goal is to re-create the CAD model as close to the original designs of its creator. In manufacturing, parts may have the tendency to shift slightly based on the tolerances specified by the designer. For instance, a part may have been designed with a bore hole that is 1.5” in diameter, but the final produced part may have a diameter of 1.496” due to part variance. Therefore we would modify any bores of the 1.496” back to the original intent of 1.5”.

Reverse Engineering for Exact Replication

If requested, we can reverse engineer a CAD Model to be as accurate as possible to your original part. This type of 3D scanning is mainly used for part inspections, or objects that are not mechanical in nature but rather artistic, like museum pieces and statuary. We will not adjust for design intent, and will re-create the scan data from the object as closely as possible.

Reverse Engineering with Modifications

If a part has failed in its operation, and it now needs to be reverse engineered, then there is probably a mechanical reason that it failed in the first place. We can often make adjustments to the original designs of parts to improve on weak areas, and reinforce the parts overall  performance.
Now that you have your Reverse Engineered model, see our 3D Printing page to find out how to begin the prototyping process.

Don’t have an part to scan?  ProImage 3D can take your 2D CAD drawings and create 3D CAD models. We’ve even converted napkin sketch drawings into 3D models.
