Model.lineextenddistance

Model.lineextenddistance(line, distance, derivative, direction)

Extends the specified line.

Parameters:

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

• distance (double) – The distance to extend the line.

• 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 2 at distance of 10.0 , tangent to the line from the end of the line

import hm
import hm.entities as ent

model = hm.Model()

model.lineextenddistance(
    line=ent.Line(model, 2), distance=10.0, derivative=1, direction=1
)
