What’s new in this release

Pipe drafting in plan

Enhanced drafting control for pipe display in plan has been included. This allows users to display outer diameter, inner diameter, and centreline line work for their pipes. Users can set pipe widths in plan to reference actual pipe diameter.

We have also updated default blocks for inlet pits and catchment areas.



A new command named Threads has been added to the software. A Thread is a collection of actions or commands that can be computed as a single process. This means that rather than constantly needing to run update commands in Civil Site Design, users can create a Thread, which will process a number of commands in the one button click.


A Thread could also be used for the purpose of plan production. For example, a Thread could be created to plot cross sections and long sections, update setout information and produce all CAD line work.

Check out this video for more information on Threads.
