Model.lineextendtonode#

Model.lineextendtonode(line, node, capture_radius, derivative, direction)#

Extends the specified line to a node.

Parameters:

  • line (Entity) – The line entity to extend.

  • node (Entity) – The node entity to which the line is extended.

  • capture_radius (double) – If the point at the end of the extension is within the capture_radius of the node, then force the end point to have the same coordinates as the node.

  • derivative (int) –

    1 - Extend the tangent to the line

    2 - Extend following the curvature of the line

  • direction (int) –

    -1 - Extend the beginning of the line

    1 - Extend the end of the line

Example#

Extend the line with ID 1 to the node with ID 2 with a capture radius of 1.0 . The extend line should be tangent to line and extended from the end of the line .#
