Dana Judge
Beth holds an Associate’s Degree in Architectural Engineering and brings over twenty years of experience to the AEC industry. As a Digital Delivery Leader for Transit and Rail, Beth supports BIM management, data management, and
implementation, helping professionals leverage new technology to optimize project outcomes. Since 2005, Beth has trained and supported Autodesk users
while working with various architecture, engineering, and construction firms. She is dedicated to improving workflows and believes that effective use of emerging BIM and data management technologies increases value and minimizes waste
throughout every phase of a project.
Dana brings more than 30 years of experience in the AEC industry and holds a B.A. in Geography from the University of New Hampshire. As a Principal Business Consultant at Autodesk, she leverages her experience
with the Civil Infrastructure toolset to help organizations advance their BIM for Infrastructure and Digital Delivery capabilities.
Over the past four years, Dana has partnered closely with GFT’s Digital Delivery team on a range of Transit and Rail initiatives, guiding the
adoption of 3D workflows that enhance project coordination, quality, and deliverable efficiency. Her deep understanding of digital design
processes and her collaborative approach have been instrumental in enabling teams to transition seamlessly from traditional 2D methods to data-driven 3D project delivery.
Greg brings over 15 years of experience in the AEC industry, with focus in the Transit & Rail industry. At GFT, Greg is the Design Technology Manager within the Transportation Business Group specializing in design drawing production
and document management. Greg holds a Bachelor's Degree in Engineering Management and an Associated Degree in Architectural and Engineering
Technology.

Strategy Learnings
New for Civil 3D (or not)
- UI and workflows do not align (design core does)
- Linear to singular modeling (both section based)
- Mixing geometry and styles (already there)
Implementation potential
- Elevating CAD content to C3D
- Bringing rail disciplines together in C3D
- Accessing all capabilities that already exist in C3D
Partnership
- Joined team of GFT and Autodesk experts
- For every obstacle, we quickly found a solution
- Supporting both the now, tomorrow and the future
