Model Maker

Model Maker

Model Maker is a digital terrain modelling program and the most advanced in the Model Maker Systems software suite. The program consists of 21 modules, which are available in four different versions of the program. The versions are determined by the number of survey points that each can model. This modular design gives users access to only those features required for their specific application thus reducing the cost of the software.

Provision is made to input data manually using various land survey methods, importing data from electronic data recorders or GPS system and from various fixed and free format ASCII files. Data can also be captured from existing drawings in DWG/DXF/DGN/SHP etc.

In addition, a facility exists to survey new data or to use an existing model to do real-time setting out work on site by connecting a notebook to an electronic survey instrument in the field.

The model is created using a fast automatic triangulation routine with or without parameters. After the DEM model is created the user has full control with built in functions provided for editing the model graphically. Contours and triangulation is edited in real time either manually or electronically to defined break lines. Break lines can be automatically created by using points from the survey.

Once the model is created various calculations can be done, e.g. four methods of calculating volumes, extracting long or cross sections, slope and watershed analyses, three-dimensional viewing, area (plan and surface) and perimeter calculations, automatic toe point generation for platforms, mine planning, rehabilitation (landscaping) of excavations and stockpiles, 3D-Mass Haul planning, power line templating, earth dam design, irrigation design and almost anything in between.

Output of results may be printed or saved and drawings may be plotted directly to any HPGL-compatible plotter, plot file or various CAD data exchange (DWG,DXF,DGN etc.) and various ASCII formats.


Why modules? - So that each user can customize his own package saving the user costs.

Required Modules (Suggested Modules)

This module is used to manipulate co-ordinate data from various sources by automatically creating a triangulated terrain model. This triangulated model can then easily be edited to display geographical contours. The contour intervals and labeling positions can easily be changed and manipulated. The user can use break lines to define valley and ridge positions upon which the software will automatically adjust the triangle model to the correct scenario. Data can be edited graphically or in text mode. The user has full control over the triangulation process with real time triangle editing tools that give live feedback as you work.


Required Modules: 1 (6)


This module is required for any graphical output. The output is determined by using an extensive range of user-definable plotting parameters and the graphical setting of plotting windows covering the total project area. Contours, survey point information, co-ordinate grids and CAD data can be plotted. Plotting can be done directly to any Microsoft Windows® printer/plotter driver as well as the following electronic formats: DWG, DXF, DGN, SHP, TXT, PNG, JPG, TIF, CEX, DRW, MOSS, GENESIS


Required Modules: 1,2 (6)

Model MakerWhen dealing with stockpiles or quarries (single surface models) this module can be used to calculate the earthworks volumes using contours, triangles or cross-sectional areas. The analysis function calculates the sloped surface area, as well as plan area. Slope analysis is pplotormed by colouring the terrain with different colours depending on the degree of steepness. Height analysis can be pplotormed by also using colouring indicating the differences in elevation across a terrain model. Valley analysis is pplotormed by indicating watershed lines and valley positions indicating water runoff patterns. Long-section or cross-section data is extracted along a horizontal alignment which can be defined on the graphic screen or can be captured from CAD entities. These data values are recorded to a text file for use with other modules.


Required Modules: 1,2 (6)

Model MakerModel Maker can be used to simultaneously model up to 21 DTM (digital terrain models) surfaces. Calculations can then be pplotormed between any two of theses surfaces. Where the designed surface (second surface) is a terrace that must meet the ground model (the first surface) at specified batter slopes, MODEL MAKER will automatically determine these toe points on the ground. The terrace level can be automatically re-elevated in order to balance the cut and fill earthworks. Bulking and compaction is also taken into consideration as well as batter slopes. Once the two models have been created, the earthworks volume can be calculated using cross-sections or a more accurate grid method.


Required Modules: 1,2,6


Model MakerUse this module to view the active model from any side at a vertical angle in a wire-frame grid or solid triangle fill format. Contours at a user-specified interval can be displayed and the full view can be converted to the CAD environment into virtually any electronic image format like bmp, jpg, tiff etc. You may also edit your triangle legs in this view. This function works pplotectly for triangulation that has to represent vertical excavation terraces.


Required Modules: 1,2


Model MakerThis module is a comprehensive CAD module with all the basic drawing functions intelligently linked to the DTM data to create detailed survey maps. A drawing can consist of any number of drawing elements, e.g. lines, circles, text, dimensions, hatching, etc. on different layers with a variety of pen, line and font types. This module is needed to load third party CAD into Model Maker. It is especially useful to convert CAD line entities e.g. contours into live DTM models. This module is excellent CAD at a very reasonable price and becomes a added design tool with intelligent functions only available to Model Maker.


Required Modules: 1,2,3,6


Model MakerGround cross- and long section data extracted using module 3 can be loaded and plotted into the CAD module (module 6). The user can specify a horizontal and vertical scales, plotting paper sizes and a layer names.


Required Modules: 1,2,3


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.

Module 9 - OPENCAST MINE PLANNING(Strip blocks, Volumes and Ratio)

Required Modules: 1,2,4,6,7(11)


Model MakerIn initial planning for an opencast mine operation this module can be used to calculate volumes between different material layers or strata. Borehole data is used to create up to 50 models defining the different strata. The mining areas (strips) within which opencast mining must be done can be defined as geographical areas and volumes or average depths can be calculated between different strata within each strip area. Any plan area can be defined. Each area is then numbered and its area and boundary perimeter is calculated.


Module 10 - BOREHOLE MANAGER (Geology, Soil Sampling)

Required Modules: 1,2,5, (4,6,11)

Bore Hole ManagerGeological data or soil sampling logs can be entered (or imported from Excel CSV format) into a convenient borehole data manager. Borehole logs can then be individually mapped and coloured with a drag and drop feature to represent different soil seams. Boreholes can be graphically compared with each other. Strata/seam layers can be exported to DTM where it can be viewed in 3D to evaluate the seam structure and to easily determine data input errors. This data can then be used to calculate the volumes of the different seams using Module 4 (Module 4 needs to be added separately).


Required Modules: 1,2,(6)

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


Required Modules: 1,2,11

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.

Module 13 - Mass Haul AND VOLUME CENTROIDS

Required Modules: 1,2,4,6

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.


Required Modules: 1,2,4,6,11

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.


Required Modules: 1,2,6,11


Model MakerThis 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.


Required Modules: 1,2,11


Model MakerIndicate 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.




Required Modules: 1,2,6


Model MakerThis 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. Analyzing 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.


Required Modules: 1,2,3,6


Model MakerDesigning the horizontal alignment geometry of a road is supported by using this module to determine sight distances on horizontal curves. Vehicle turning circles may also be tested graphically within confined areas. The test vehicle dimensions and parameters may be fully defined by the user and the result is a graphical output of sight lines or vehicle wheel paths.



Module 19 - WGS84 CONVERSION  

Required Modules: 1,2

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


Required Modules: 1,2,3,6

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.


Required Modules: 1,2,3,6,11

This module is used to calculate the minimum drainage connection height at the main sewer connection for each township plot. This automated action will then create a plot 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.
