Contour Parameters

This dialog box allows you to set the way contours will be generated and displayed.
Enter the Minimum and Maximum RL value in the contours. Only contour levels between these values will be displayed. If these fields are left blank, all contours will be displayed, from the lowest level in the job to the highest.

Cont Visible - Turns the contours layers on or off, this is the same as making the contours layers visible or not using the Layers option

Check the Smooth Contours box to draw smoothed contour lines. If left unchecked, straight contour lines will be drawn. Straight lines are faster to draw and easier to work with on the screen

The Advanced button allow you to change the way contours are drawn. You can alter the ‘roundness’ the cut off angle and the plot increment.
See Contour Smoothing for more details.



Contour Banding
Allows you to change the colour properties for the different contour heights.

Minor Contours
Interval – this is the vertical distance between contours, choose an appropriate value for your job, usually 1m.

Choose the Colour for the minor contours. It is usually best to leave it ‘By Layer’ so that the colour can be determined by the layer for all contours. Note: This colour will only be set onto the contours when the contours (polylines ) are formed, when triangles are formed or the apply button is pressed. Click here for Colour chart.

Choose the Layer for the contours and the height text. The text will use the font, colour, size and style of this layer. Press the New button to create a new layer.

Check the Height Text check box if you want the minor contour heights to be inserted into the job as text elements.

Major Contours
Interval – this is the vertical distance between contours, choose an appropriate value for your job, usually 5m.

Choose the Colour for the major contours. It is usually best to leave it ‘By Layer’ so that the colour can be determined by the layer for all contours. Note: this colour will only be set onto the contours when the contours (polylines ) are formed, when triangles are formed or the apply button is pressed. Click here for Colour chart.

Choose the Layer for the contours and the height text. The text will use the font, colour, size and style of this layer. Press the New button to create a new layer.

Check the Major Contour Heights check box if you want the major contour heights to be inserted into the job as text elements.

Check the Height Text check box if you want the major contour heights to be inserted into the job as text elements.
