Software -SMIGS

By Mask - Strings can be selected by name or part thereof by use of masks for manipulation. A mask can be deleted, copied, moved, clipped, linked, scaled, rotated, edited, converted, etc.

By Fence - A fence (window) of any shape can be placed around certain strings to restrict manipulation of strings to the ones that fall inside the fence. A fence can be deleted, copied, moved, clipped, linked, scaled, rotated, edited, converted, etc.

String Manipulation
Individual - Strings can be deleted, copied, moved, clipped, linked, scaled, rotated, edited, converted, etc.

Perspective - Wire frame, Hidden line, Rendered, Animation / Drive Through (SGI only).

Viewing
Plan Fit view (extents), Update, Pan, Window In, Full view, String view.

Annotation and Labelling - Numerous attributes and other types of data can be labelled or annotated permanently.

Feature Coding - Automatic assignment of cells and symbols to strings and points.

Symbols/Cells - Libraries of symbols may be inserted into the model by reference (the cell is treated as a separate entity, and is referenced to coordinates in the current model), thus significantly reducing the model size.

Text - Vector drawn text and True-Type fonts fully supported with 12 point justification.

CAD
3D Coordinate Geometry - Location of points at nominated bearings, angles or distances. Projection of point from nominated strings. Intersection of strings. Creation of tangent points to strings. Fillets between nominated strings. Division of strings. Creation of parallel strings. Perpendicular strings created from nominated strings.

Macro Language
BASIC like language with access to most of the features in SMIGS which makes this a very powerful and flexible way of extending the functionality of SMIGS according to the individual needs.

Plan Annotation - Automatic annotation of lot numbers, layers, bearings, distances, point numbers, etc.

Minimum width

Parallel sides

Specified frontage

Manual

Subdivision
Lot Definition - The following options are supported:

Material Takeoffs - Measurement of material takeoffs associated with length, areas and volumes.

Batters - Simple - creation of interface string using a single slope batter. Compound flexible way of creating several interface strings by using user definable multislope batters.

Earthworks
Volumes - Sectional (End-Area Method)- volumes are calculated to RL, to RL along a string, between models and between models along a string. Prismoidal - to RL and between models.

Vehicle Turning Path - Calculation of the swept path of standard and user defined vehicles turning a curve.(additional module)

Superstrings - Combined horizontal and vertical design in which new strings are created from either a reference, subsidiary, or both.

Templates - Flexible way of automatically generating pavement, batters (including tick marks to indicate cut and fill), cross sections, volumes and kerb/lane/footpath strings of a road pavement all in one hit.

Vertical - IP-method - similar to horizontal but curves can be placed according to length, radius, control point or pipe joint deflection. Splines - A spline is fitted through all points defined. Constraints may be placed to cheek against certain values. Sight line, reaction time and speed data fully supported.

Road/Railway Design
Horizontal - IP-method- Intersection Points are placed, after which the curvature gets defined for each one either with or without leading / trailing spiral. Dynamic Elements - Straights and arcs with 0/1/2 degrees of freedom are connected by a multitude of possible connections.

Plotting - SMIGS plots using HPGL.

Macro Language - SMIGS includes a sophisticated yet easy to use Macro Language (SML) which is used for functions ranging from tailoring the user interface through to complex design automation. SML incorporates powerful calculation and reporting facilities as well as trigonometric functions, manipulation of character-strings and enhancement features such as colour-shading of TIN triangles according to geometric attributes. Based on the BASIC programming language, it permits direct read/write access to the SMIGS model, to external files and can even execute external programs which analyze and/or generate model data. The language includes access to every on-screen menu function in SMIGS as well as a comprehensive library of subroutines. SMIGS is shipped with working examples of all SML functions and subroutines, many of these Macros provide useful standalone functions in their own right.

Multiple Layers - SMIGS supports 180 layers for data discrimination, each layer able to be named by the user. Layer attributes are held against each data entity, allowing the user to work within the model on a "What-You-See-Is-What-You-Get" (WYSIWYG) basis. Additionally, each entity can also be named and this attribute can be used for sophisticated mask-based model manipulation if desired. These features contribute significantly to the power and ease of use of the package.

String Modeling - By adopting a string-based approach to design, SMIGS improves processing and interpretation of large volumes of data. Graphic primitives, such as contours, feature strings or road centre-lines are modeled by lines connecting a series of points. These lines are called strings. Because each string is stored and manipulated as a single entity, exceptionally high interactive speeds are achieved. Data types supported within SMIGS include: contour strings, feature strings, grouped entity sets, text, circular arcs, spirals, meshes, surface polygons and user defined symbols.

Unlimited Model Size - SMIGS has NO limits to the amount of data in any one model. In addition, SMIGS has the powerful ability to operate on models composed of other models; to "cut" out an area for manipulation and "paste" it back into a model, effectively eliminating the need to work on an entire model for particular design projects.

SMIGS Unique Features
