12d Model Course Notes and Data Sets

ExDS runs training sessions for 12d Model on a regular basis in Sydney, Adelaide, Newcastle and Canberra. Our most popular sessions are the ‘12d-1A Introduction to 12d Model' and '12d-2C1 Basic Civil Design' courses.

Printed course notes are provided to everyone who attends any of our training courses, and the notes and data sets used for the '12d-1A Introduction to 12d Model' and '12d-2C1 Basic Civil Design' courses can be downloaded using the links below.

12d-1A Introduction to 12d Model

The Introduction to 12d Model session is a full day course which covers the basic principles of modelling ground features using 12d Model. The course covers importing data, measuring and inquiring the data then triangulating it to form a ‘Triangulated irregular network’ (tin). We create contours from the tin, then move on to cover the basics of drafting in 12d Model and simple plan plotting. We finish the course by using these new skills to create an outline for a building pad, and batters for the pad to natural surface. Once the building pad has been created Volume calculations can then be calculated to determine the cut and fill for the design.

12d-2C1 Basic Civil Design

The Basic Civil Design session is a two day course which covers the basic principles of civil engineering design using 12d Model. On day 1 the course covers importing and triangulating survey data, creating a road centreline using super alignments and design templates. These three parts are brought together using an Apply Function to create the road design. Two roads are created one a ‘highway’ across the site, another a local ‘subdivision’ road. Students can ‘drive’ on their roads, and plots of plan, long sections & cross sections are produced.

On day 2 the course covers creating another road design of 2 roads and an intersection. The road designs are created using the Apply Many Function and MTF file. The design features covered on day 2 are creating the intersection, by stopping and starting the design templates through the intersection, creating kerb returns, lane widening, superelevation and a bus bay design. To modify the design templates the MTF modifier options are used.

Elements of the Super Alignment String

The Super Alignment String allows the designer two methods for defining an Alignment String, that is the traditional I.P. method, and Element Based design (also called 'Parametric Design' or simply 'Fixed & Floating').

Using Elements for the Alignment String allows more ways to define the geometry of the alignment than the I.P. method, but with the power comes complexity.

Elements are put to best use on intersections, roundabouts, kerb returns, and any other 'tricky' geometry.

EXDS regularly runs training sessions on the Super Alignment in the 12d-2C2 Intermediate Civil Design Course, and we normally spend about an hour talking about the theory involved in using Elements.

The pdf file available from the link below is the first part of the course notes for our 12d-2C2 Intermediate Civil Design Course which incorporates the Super Alignment design, and covers a little of the theory of 'Elements'.
