======Manipulate mesh sections======

Isolate sections of a mesh and move them independently from the whole. Currently, you can only manipulate meshes assigned to Frond generators.

=====Prerequisites=====

  * A Frond generator with a material and mesh assigned.

=====Manipulate mesh sections=====
To manipulate mesh sections, you need to identify the sections and adjust the appropriate generator properties. All painted areas in one section move together when you adjust the properties.

====Identify sections of a mesh====

To identify sections of a mesh:
  - Open a mesh in the [[toolcutout_editor|Cutout Editor]]. The mesh must be assigned to a Frond generator.
  - From the Paint group, select **Section**.
  - Paint the areas of the mesh you want to manipulate. Adjust the brush size for precise painting, and use falloff to create soft transitions between painted and unpainted areas. To create multiple sections, select **New section** from the dropdown menu.
  - Save the mesh to the High, Medium, or Low slots.
  - Close the Cutout Editor.

====Adjust generator properties====
To manipulate the identified mesh sections:
  - Open the Frond generator properties where the mesh is assigned.
  - In the Shape group, modify any values under [[frond_generator#section variance|Section Variance]].
