12d Model (Intro)

A one-day course for people with little or no experience with 12d Model. At the end of this course you will be familiar with 12d Model, able to load and triangulate survey data and create contours for plotting and export to CAD, able to use the more common drafting tools in 12d Model, and will have had exposure to the techniques of surface modelling for design, analysis of surface features, and calculation of earthwork volumes.

Course Outline:

• Start a new project, and load survey data from DXF or CivilCAD and save the project.
• Interrogate the data using inquire and measure tools, and display elevations and codes on-screen.
• Use the survey data to create a triangulation (TIN), then edit the TIN (remove long triangles, flip triangles etc).
• Create Contours from the TIN, plot these to pdf, and export to dwg format.
• Use 12d Model’s CAD tools to draw lines and arcs, create offsets and fillets.
• Analyse a ground surface to determine the parts of a site suitable for development.  Colour the site based on the slope of the surface.
• Use 12d Model’s CAD tools to create the outline of a building pad, and generate earthwork batters from the pad to the survey surface.
• Triangulate the pad design, and calculate the earthwork volumes required to build the pad.  Adjust the height and position of the pad to minimise and balance earthworks volumes.
• Create a combined water quality / stormwater detention basin.  Triangulate the basin, and calculate the earthwork volumes required to build the basin.  Calculate the volume of water that can be stored in the basin, and generate the staged storage curve.
