Parameters for Creating Single Elements

Modify Element Parameters (Create Simple Element)

You can set the following parameters on the Context toolbar.

XA

YA

Alpha

Parallel

Arc Length

Rad (Rs)

Rad (Re)

A

Depending on which parameters you set, you can create geometric primitives such as lines, circles and clothoids (spirals):

• To create a line: set the radius at the start point (Rad (Rs)) and end point (Rad (Re)) to 0.
• To create a circle: set the radius at the start point (Rad (Rs)) and end point (Rad (Re)) to the same value.
• To create a clothoid: set the radius at the start point (Rad (Rs)) and end point (Rad (Re)) to different values.
• The element length will not change when the radii are altered. Similarly, changing the element length or clothoid parameters will not affect the radii.
