Extracting Outer Surface Area Parameter for the Drawing

In the design process, when outer surface area is required for coating treatment for set of assembly parts, SHRINKWRAP technique can be useful as described in this video. In this, you would find:

1. Extracting the outer surface geometry,
2. Creating Area Measure Feature
3. And Calling out the Area Parameter in the Drawing from the measure feature.

Let me know in the past how you would have managed to achieve this or any suggestions…
