Googong Township Neighbourhood - Stage 1A

Project Summary

As a part of the design process for sewer and stormwater analysis, the layout and numbering of a network was drafted in another software package. Part of the process for transferring this network to 12d Model was node numbering. Projects as large as Googong Township (over 2 stages) include well over 300 nodes.

The Challenge

Manually numbering such an enormous network can be very time-consuming. The team needed a quick and simple process to transfer the node numbers into 12d Model.

The Solution

Once the network had been drafted, complete with node numbers, and created in 12d Model, the team was able to use the import/export feature from the Drainage Network Editor (DNE). Using a customised list file, they exported the following:

• String ID

• Pit id

• Pit centre x

• Pit centre y

They developed a LISP routine to read the data from the customised list file. This routine then exported the number attribute associated with each node and created another custom list file with the following:

• String ID

• Pit ID

• Pit name

Using the Drainage Network Editor’s ability to read data from the clipboard, the data was read in and all nodes updated with their correct numbers.

The Result

This simple process saved the team incredible amounts of time, eliminated errors and ensured consistency between 12d Model and other software.
