Cleanup
=======

Cleanup tools remove unwanted elevation or duplicate geometry so
drawings stay flat and tidy for 2D delivery.

   single: FLATTEN

FLATTEN
-------

Sets **Z = 0** on the selected objects.  For polylines, the
**Elevation** property is zeroed as well so DXF/IQZ export stays
consistent.

**Access**

- Ribbon: **Super Tools → Cleanup** (default click) or the Cleanup
  dropdown → **Flatten**
- Menu: **Super Tools → Cleanup → Flatten**
- Command line: ``FLATTEN``

**Workflow**

1. Optionally pre-select the objects to flatten.
2. Run ``FLATTEN``.
3. If nothing is selected, pick objects and press **Enter**, or press
   **Enter** immediately to flatten **all** objects in the drawing.
4. The command line reports how many objects changed.

**Notes**

- Undoable (full vertex Z and polyline Elevation restore).
- Non-zero Z only: objects already at Z = 0 are left alone in the
  change count.
- Formerly available under **Modify**; it now lives only under
  **Super Tools** so cleanup stays with other Super Tools utilities.
  The command name ``FLATTEN`` is unchanged.
