C3D is able to open older LDD files and offers: We’ve used this software for more than eight years, with C3D replacing our previously used AutoCAD LDD software.

AutoCAD Civil 3D (C3D)ĪutoCAD C3D software is used primarily for earthworks projects such as landfills, quarries and subdivisions. We used 12d Model software to design the 7.5km-long Northern Gateway motorway extension to the Northern Motorway in Auckland, the Waterview Connection tunnels and numerous landfills throughout New Zealand. Smooth data exchange with software such as MX Road, AutoCAD and AutoCAD Civil3D.Powerful string-based terrain modelling.12d Model software is ideally suited to alignment design and offers: It’s the main design software used for road, rail and tunnel alignment projects and for land development projects such as subdivisions, quarries and landfills. Our design team has been using 12d Model software for more than 15 years. This ensures we provide efficient and productive services, using up-to-date industry standard software 12d Model

Our CAD team offers a high level of technical expertise and a strong team culture. These include the SH20/20A Extension to Mangere Airport and Northern Gateway (Albany - Puhoi motorway extension) roading projects in and north of Auckland, along with Auckland’s Vector Tunnel and Canterbury’s Kate Valley and Redvale Landfills. Our strong track record in these areas includes significant contributions to many high-profile projects. We offer specialist design services for infrastructure, land development and solid waste sectors. Tonkin + Taylor’s Computer Aided Design (CAD) team continues to expand to meet client needs and expectations.
