Civil Designer is the design system created by civil engineers for civil engineers. The world-class software platform consists of a suite of fully interactive design modules which combine to form an integrated data gathering, drawing, surface modeling and design system for civil engineering infrastructure. Design Centre lets you read in and reduce survey data from various sources. We support a number of data logging programs and total stations. The terrain database has a theoretical limit of two thousand million points. Actual capacity will depend on available disk space. Data may be allocated into one of 128 terrain surfaces or road layers. CREATE DIGITAL TERRAIN MODELS (DTM) You can create a digital terrain model from the raw coordinates with full control over the break and feature lines on the site. If you want to remove the background clutter simply filter the points display to show only certain points and break lines. When you use the interactive graphical functions to manipulate the data the contours will be updated as you change the break or feature lines.
