This tool allows to set the slope (vertical horizontal) of selected wires or lines. By setting a slope value, all vertices after the first one will have their Z value changed so the different segments of the wires or lines will have the given inclination.

For a selected [[Draft Line]] or [[Draft Wire]] drawn on the XY plane, the Draft Slope tool increases the Z coordinate of all vertices after the first one, so that the line or wire has the defined slope.
The slope value is a tangential value: 0 means horizontal, 1 means 45 degrees upwards, -1 means 45 degrees downwards, 0.577 means 30 degrees up, etc.

The slope value is the [https://en.wikipedia.org/wiki/Trigonometric_functions#tan tangent] of the elevation angle:
* 0 means the line is completely horizontal, because tan(0°) = 0.
* 1 means 45 degrees up, because tan(45°) = 1.
* 0.577 means 30 degrees up, because tan(30°) = 0.577.
* 1.732 means 60 degrees up, because tan(60°) = 1.732, etc.

<!--T:7-->
Negative values are also possible:
* -1 means 45 degrees down, because tan(-45°) = -1, etc.

Description

For a selected Draft Line or Draft Wire drawn on the XY plane, the Draft Slope tool increases the Z coordinate of all vertices after the first one, so that the line or wire has the defined slope.

The equivalent action is editing the object and moving the points manually to a new position.

Horizontal line; line with slope changed to 45°

Usage

  1. Select a Draft Line or Draft Wire object.
  2. Go to the menu Draft → Utilities → File:Draft Slope.png Set Slope.
  3. Set the desired slope value, and press the OK button.

The slope value is the tangent of the elevation angle:

  • 0 means the line is completely horizontal, because tan(0°) = 0.
  • 1 means 45 degrees up, because tan(45°) = 1.
  • 0.577 means 30 degrees up, because tan(30°) = 0.577.
  • 1.732 means 60 degrees up, because tan(60°) = 1.732, etc.

Negative values are also possible:

  • -1 means 45 degrees down, because tan(-45°) = -1, etc.
