Shape

A Rectangle profile can be used to define the shape of a tunnel in cross-section. Set the following properties of the Rectangle shape:

Width (X)

Enter the Width labelled as X in the panel showing the shape display. Optionally, double-click to select the name of a field containing Width values in the String file. The values in this field will be used to control the width of the extrusion.

Height (Y)

Enter the Height labelled as Y in the panel showing the shape display. Optionally, double-click to select the name of a field containing Height values in the String file. The values in this field will be used to control the height of the extrusion.

X offset

This field controls the horizontal position of the extrusion relative to the centreline and defaults to negative half the width of the extrusion. If the field is empty it will default to zero.

Y offset

Defaults to zero. Optionally, enter the distance the extrusion will be offset from the centreline in the Y direction.

Rotation (Deg)

Enter a Rotation value in degrees. Enter a value (0° to 360°) if you want to rotate the profile shape. Use positive or negative values to rotate in a clockwise or anti-clockwise direction.

The default profile shape for a vertical shaft is a Circle. Set the following properties of the Circle shape:

Radius / Point Count

Enter the radius of the vertical column and the number of points used to construct the circle. As you use the increment/decrement controls, the shape of the column will change in the Preview window.

X offset

This field controls the horizontal position of the extrusion relative to the centreline and defaults to negative half the width of the extrusion. If the field is empty it will default to zero.

Y offset

Defaults to zero. Optionally, enter the distance the extrusion will be offset from the centreline in the Y direction.

An Arch by Heights profile can be used to define the shape of an arched tunnel, where the shape of the arch is determined by its height and the number of points. Set the following properties:

Width (X)

Enter the Width labelled as X in the panel showing the shape display. Optionally, double-click to select the name of a field containing Width values in the String file. The values in this field will be used to control the width of the extrusion.

Height (Y)

Enter the Height labelled as Y in the panel showing the shape display. Optionally, double-click to select the name of a field containing Height values in the String file. The values in this field will be used to control the height of the extrusion.

Arch Height (h)

Enter the height of the arch.

Point Count

Enter the number of points used to construct the arch. As you use the increment/decrement controls, the shape of the arch will change in the Preview window.

X offset

This field controls the horizontal position of the extrusion relative to the centreline and defaults to negative half the width of the extrusion. If the field is empty it will default to zero.

Y offset

Defaults to zero. Optionally, enter the distance the extrusion will be offset from the centreline in the Y direction.

Rotation (Deg)

Enter a Rotation value in degrees. Enter a value (0° to 360°) if you want to rotate the profile shape. Use positive or negative values to rotate in a clockwise or anti-clockwise direction.

An Arch by Radius profile can be used to define the shape of an arched tunnel, where the shape of the arch is determined by maximum width and height values, a radius and a point count.

Width (X)

Enter the Width labelled as X in the panel showing the shape display. Optionally, double-click to select the name of a field containing Width values in the String file. The values in this field will be used to control the width of the extrusion.

Height (Y)

Enter the Height labelled as Y in the panel showing the shape display. Optionally, double-click to select the name of a field containing Height values in the String file. The values in this field will be used to control the height of the extrusion.

Radius (r)

Enter the radius of the arc. Depending on the radius, the arch can take one of three forms:

1. A radius of zero will produce a square with four points.

2. A radius < half the width will produce rounded corners. An arc on each shoulder.

3. A radius > half the width* will produce a rounded top. A single arc.

   *Profiles with a very short height to width ratio will only produce a single arc when the radius is large enough to produce valid geometry. The profile will always give the Width and Height properties a higher priority than the Radius.

Point Count

Enter the number of points used to construct the arch. As you use the increment/decrement controls, the shape of the arch will change in the Preview window.

X offset

This field controls the horizontal position of the extrusion relative to the centreline and defaults to negative half the width of the extrusion. If the field is empty it will default to zero.

Y offset

Defaults to zero. Optionally, enter the distance the extrusion will be offset from the centreline in the Y direction.

Rotation (Deg)

Enter a Rotation value in degrees. Enter a value (0° to 360°) if you want to rotate the profile shape. Use positive or negative values to rotate in a clockwise or anti-clockwise direction.

An Arch by Ratio profile can be used to define the shape of an arched tunnel, where the shape of the arch is determined by its height, width, the ratio of the arch and the number of points. Set the following properties:

An Arch profile can be used to define the shape of a tunnel in cross-section. Set the following properties of the Arch by Ratio shape:

Width (X)

Enter the Width labelled as X in the panel showing the shape display. Optionally, double-click to select the name of a field containing Width values in the String file. The values in this field will be used to control the width of the extrusion.

Height (Y)

Enter the Height labelled as Y in the panel showing the shape display. Optionally, double-click to select the name of a field containing Height values in the String file. The values in this field will be used to control the height of the extrusion.

Arch Ratio (r)

Enter the ratio of the arch.

Point Count

Enter the number of points used to construct the arch. As you use the increment/decrement controls, the shape of the arch will change in the Preview window.

X offset

This field controls the horizontal position of the extrusion relative to the centreline and defaults to negative half the width of the extrusion. If the field is empty it will default to zero.

Y offset

Defaults to zero. Optionally, enter the distance the extrusion will be offset from the centreline in the Y direction.

Rotation (Deg)

Enter a Rotation value in degrees. Enter a value (0° to 360°) if you want to rotate the profile shape. Use positive or negative values to rotate in a clockwise or anti-clockwise direction.
