Entry Path Radius

Specify the entry path radius value. This is the radius of the path which the design vehicle travels from the entry approach leg to the circulatory path.

Entry Path Radius Start

Specify the entry path radius start value. This is measured from the inscribed circle diameter to the start of the first radius in the biarc entry.

Secondary Entry Path Radius

Specify the secondary entry path radius value. This is the second radius of the path which the design vehicle travels from the entry approach leg to the circulating path.
