The Draft Slope command slopes selected Draft Lines or Draft Wires by increasing, or decreasing, the Z coordinate of all points after the first one. It can also be used to flatten Draft Wires. Note that the slope is relative to the XY plane defined by the DataPlacement of the objects.

On the left a horizontal Draft Line. On the right the same line with a slope value of 1 (angle is 45°)


  1. Select one or more Draft Lines and/or Draft Wires.
  2. There are several ways to invoke the command:
    • Press the Set slope button.
    • Select the Modification → Set slope option from the menu.
  3. Enter a Slope value. 0 means each segment is horizontal, 0.5 means the delta height for each segment is 0.5 times its length, etc. The value can also be negative.
  4. Press Enter or the OK button to finish the command.

There is no Python method to slope objects. To emulate the results of the Draft Slope command the Points property of wire objects has to be modified.
