Solid Modeling

Solid modeling is definitely my main tool for design.

I've used different packages. 3D CAD Modeling in Solidworks after 2006, ProE before that, SDRC Ideas before that. My job is primarily tuned to internal reinforcements and strapping retention anchors, fit system components etc...but I'm not beyond doing full helmet cad from white light scanned hard models. All helmets are now released to the tooling vendors in CAD form.

The projects shown here are mostly reworking of white light scan data into tooling surface cad for tooling release to the vendors. White light scans are used to covert the clay and bondo models made by hand by Industrial Designers into computer cad data. Knowledge of how EPS tools are made is required to accomplish correct draft and estimation of tool component parting lines.

Scan data looks like an alligator's skin and not suitable for machining path code. It needs to be reworked. This project was done for Giro.
A Bell helmet which was reworked then scanned, tooling cad was created in Solid Works.
This Giro model is one of their Spherical MIPS helmets. Therefore, it has an upper and lower body. Both are resurfaced from scan data to tooling cad.
A proto-type vacuum formed polycarbonate cap intended for the Aeon proto-type tool.

This is an antiquated method for fitting an internal plastic inject molded reinforcement...sometimes called a roll cage. This was done pre-2010.
