Being able to shift, scale and rotate coordinates is a regular requirement of Engineers working with various building components and methods.


This function was added to assist Engineers in computing position and level around a road junction where the intersection of two joining channels are calculated and levels attached around a curve by forming a plane through the tangent points and intersection

An Engineer will rarely be able to mark out a line on the ground directly where something has to be constructed, he will invariably need to offset it by an amount to allow for working space. This is one of the many uses of the parallel line function

The intersection of two gradients is needed when an Engineer wants to calculate the properties of a vertical curve.

Finding where lines will intersect on the ground has many uses for the Engineer, perhaps in marking out road junctions or finding where pipes clash underground.
CoGeo will handle all 3 types of lines, straights, curves and spirals.

Many design schemes such as roads and railways use a reference line built up of straights curves and spiral curves to indicate it’s position. Most of the salient information is computed by distance along and offset to this line and computation is required to determine these points, CoGeo provides a simple interface for this. When the Engineer needs to check a points position to the reference line it is a simple matter to select the alternative tab converting coordinates to distance and offset.

Setting out is an important part of any construction operation, it involves marking out by various means the lines and levels of the various construction components and operations. Engineers often work in difficult site conditions and are relied on to produce consistently accurate information to tight time schedules. The information they are given to work with can involve much manipulation and computation but their work rarely goes recognised until they make a mistake. CoGeo attempts to give these stalwarts of the construction industry a helping hand.
Converting rectangular coordinates to polar is fundamental in allowing an Engineer to position a point on the ground from a known position using angle and distance measuring equipment.
The opposite function is provided as well so he can check his work by radial observations.

For a vehicle to change direction at speed it is essential that a smooth arc is formed. Spirals or ‘clothoids’ are used to join arcs and straights and this function computes the salient points for the Engineer to layout the curve on the ground
DXF is drawing interchange format developed by Autodesk to facilitate exchange of drawings between their drawing package AutoCad and other CAD packages. Contractors are very often given these DXF drawings by a designer and the Engineer must interrogate the drawing, measuring between lines or points and selecting positions which he needs to mark on the ground either by direct selection or by extending lines or offsetting them.
