The slope value is the tangent of the elevation angle:
* 0 means the line is completely horizontal, that is, tan(0°) = 0.
* 1 means 45 degrees up, that is, tan(45°) = 1.
* 0.577 means 30 degrees up, that is, tan(30°) = 0.577.
* 1.732 means 60 degrees up, that is, tan(60°) = 1.732, etc.

Negative values are also possible:
* -1 means 45 degrees down, that is, tan(-45°) = -1, etc.

Description

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

How to use

  1. Select a Draft Line or Draft Wire object.
  2. Press the File:Draft Slope.png Set Slope button, or go to the menu Draft → Utilities → 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, that is, tan(0°) = 0.
  • 1 means 45 degrees up, that is, tan(45°) = 1.
  • 0.577 means 30 degrees up, that is, tan(30°) = 0.577.
  • 1.732 means 60 degrees up, that is, tan(60°) = 1.732, etc.

Negative values are also possible:

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