A horizontal alignment can be defined (module 3), giving the following data for each point of intersection (PI): Name ,co-ordinate ,curve radius ,transition lengths starting and ending the curve.
This module is then used to calculate setting out data of all chains as well as curve data as defined within a predefined radius from the setup station.

A geometric alignment string may be seen as a 3D poly line where each bend point/node on the line has an elevation and description. The string may be viewed and manipulated in plan or long-section format allowing the user to grade one or multiple segments in the string. Strings may be used in various design applications, e.g. slope tracking, complex terrace designs (e.g. traffic circles/roundabouts), clashing services, multi grade toe line interpolations, service crossing positioning for road designs, road edge definition and road layer inner offsets if used with Road Maker, defining pipe network layouts for use in Pipe Maker, reticulation powerlines profiling* and much more. Strings is a incredible design tool with extensive functionality and uses. Be sure to ask for more information regarding this module.

*For powerline profiling see Module 15

Landscaping of new areas or the rehabilitation of old mine dumps can be done in accordance with slope parameters in multiple directions. An existing model will automatically be updated to the predefined slope parameters to give a balanced (cut/fill) earthworks model. Geometric alignment strings can be used to define restrictions on the movement of material. Material to be imported from or exported to another area can be specified.

The movement of material in a cut/fill operation can be presented by hauling distance lines between the cut and fill areas. The total volume in a cut or fill area can be shown at the centre of that volume. This could typically be used to plan the most effective earthworks operation for the correct short distance or rather longer to long distance hauler.

Where terraces need to be designed in very restricted areas this module can be used to determine the toe perimeter of a terrace within a specified boundary. MODEL MAKER determines a final elevation, outside toe line perimeter and cut and fill volume for each terrace according to specified slope parameters.

This module uses the geometric alignment strings and CAD modules to design the route and pole positions for rural power lines (11kV and 22kV). A user-definable pole database and conductor seed file can be created. The power line is then profiled in a long sectional view where the program checks each power line pole for uplift as well as the poles wind- and weight span capability. Allowance is also made for conductor clearance distances. All service crossings is detailed in plan view and in long section view. Spanning sheets is then automatically created for construction purposes.

Indicate the centreline position of a dam wall, specify the wall construction parameters and catchment area and within seconds calculate various dam wall position options for maximized retention volumes. The results are dam wall earthworks volumes, water capacity, maximum depths and earthwork cost estimation.

This module will assist the irrigation design engineer with a flexible and indispensable tool without confining him to rigid limitations. Full graphical control over the automatic and manual design of an irrigation network is provided. Analysing the hydraulics of an open network with predefined or computer selected pipe sizes is done with ease. Global manipulation of groups of pipes and nodes may be done to optimize the design. Standard pipes, emitters and fittings may be defined in a user database. This module can be used in almost all aspects of agricultural pipe line irrigation design as well as various landscaping/turf irrigation projects. Model Maker DTM and CAD functions are available throughout the design. View the IrriMaker page for more info here.

Co-ordinates from the old South-African Clarke datum may be converted to the new WGS84 datum using this module. The WGS84 datum is implemented in South-Africa as from January 1999 and all new surveys must be done in this format. Using this module you may do a transformation of all the data loaded into MODEL MAKER i.e. DTM, CAD and geometric alignment strings. The WGS84 grid file must be parched separately for each geo-area that needs to be converted. These grids are based on the 1:50,000 map system of South Africa

After drawing the layout of a storm water pipe network and the catchment areas in Model Maker's CAD, this module may be used to create the data needed by the HYDROSIM - Storm water analysis program.

This module is used to calculate the minimum drainage connection height at the main sewer connection for each township erf. This automated action will then create a erf connection file which can be loaded into PIPE MAKER and be graphically displayed in the long sectional view of each sewer pipeline. This will assist the designer in his sewer pipeline design to ensure that the whole township is properly drained.
