The logo - graphic should encompass the concept of transferring ECAD data into a storage system for purposes of Lifecycle Management. "Keeping Data Managed and Under Control"
Some electrical Schematic symbols with a PCB (Printed Circuit Board) flowing/morphing into a manages system/product would be interesting.
Initial usage will be business cards and web page logos/branding.
Look at some of the logo/graphics associated with these companies that create ECAD data:
Companies that create PLM systems:
Logo should incorporate the company name, though they can be separate.
claesDOTbiz - though this can be emphasized in different ways and fonts to be effective; CLAESdotBIZ, claes dot biz
A tag line under the graphic and logo should encapsulate the concept:
bringing ECAD to PLM
or merging ECAD into PLM
or integrating ECAD with PLM
From the logo-design store that are close but don't make it:
99designs.com/logo-design/store/421 - good graphic, bad font
See wiki pages on PLM and ECAD:
The "cycle" or wheel theme is typical in the industry for showing the product lifecycle concept.
