1 Fill Type and Colors

Model Maker analyzes a model’s slope quickly and automatically by checking the maximum slope and direction of each triangle.

Choose one of the following methods to display the model:

1. Full fill                : A bitmap will be created indicating the slope. Colour1 shows the flattest areas and Colour2 shows steepest areas. The in-between slopes will be mixed colours.Each triangle has one maximum defined slope. Therefore, the bitmap consists of triangle images coloured according to the slope value.


2. Slope band fill : Triangle hatch areas will be defined in CAD. The colour definition is limited, (unlike the full fill option), but is controlled by the INTERVAL VALUES colour chart.


3. Arrows :
Model Maker draws arrows on the triangles at the interval specified in the CROSSES grid interval input box. Grid sizes are defined in millimeters. The actual plotting interval depends on the scale setting of the slope analysis. The colour of the arrows is also related to the INTERVAL VALUE and SLOPE CHART. Thedirection of the arrows indicates the direction of the slope. This is useful for determining water flow patterns.


4. Text     :
The slope value as a percentage will be written in each triangle. Text colours will vary according to the 6 slope intervals.
5. Range              : CAD lines will be drawn around the areas within the defined 6 slope intervals. The lines defining each slope interval will be coloured as specified. They will be on  different layers, making it easy to displaythem individually. The plan area values covered by the slope intervals are recorded and displayed in the editor.


2 Interval value and colour chart

Define up to six slope intervals from the flattest slope to the steepest slopes. The first column uses percentages, the second column uses factors: 1/(by the factor). Define one of the columns and Model Maker will calculate the other. Five colours are used to indicate the slopes between the 6 intervals. These colours relate to the CAD pen colours and may be changed by clicking on the button.

Input  interval values and change colours. Click on the coloured boxes to specify what colour you require from the colour chart.
