Command Overview

Generates a connection string between a 3D point and any points on a string which produce a predesignated angle, if possible.

Command steps:

Load your landmark point and string data. The point data represents the start of the connection string to be created, and the loaded string the destination.
Run the connection-on-grade command.
Specify the gradient of the new connecting string in degrees, to be formed between the initial point and the selected string, by entering a numeric (positive or negative) numeric value into the Gradient of Strings (degrees) field.
Click OK.

A connection string is formed between the original point and destination string if such a connection is possible.

The units and up/down convention can be modified with the set-gradient-convention command.
