Create a deformation volume¶

A deformation volume is a box of control nodes around the part of the geometry you want to deform. Every morphing task starts with one. See morphing and optimisation for how volumes work.

Before you start

Upload the Part you want to deform. See upload Parts.
Morphing uses the Part's full geometry, so you need permission to load Part files. If the Part's Viewer button is disabled with "You do not have permission to load Part files", ask your Account admin.

Open the Part in the Morphing panel¶

In the sidebar, under Setup & CAD, click Parts.
Expand the Part Library and click the Viewer button in the Part's row.
In the viewer, click Morphing. The Morphing panel opens. You can drag it anywhere in the viewer.

The Morphing button only appears when the viewer shows a single Part from the Parts page. It isn't available in the Assembly viewer or a Run's model viewer.

Create the volume¶

In the viewer, select the zones you want the volume to surround.
In the Morphing panel, click Create Volume. Bramble creates a box of control nodes bounding the selected zones.
Enter a name in Enter volume name and click Save.

Volume names must be unique for the Part, and can't contain the words "Autosave", "Empty" or "Deformed".

Tip

Make the volume only as large as the change you want. Geometry outside the volume isn't deformed, so a tight volume keeps the rest of the Part exactly as it was.

Refine the volume with more planes¶

A new volume only has control nodes at its faces. To control the deformation more precisely, add planes of control nodes inside it:

Under Plane Refactoring, click Add Bisecting Plane.
Under Bisecting Plane, choose the existing plane to add next to.
Choose Before (Negative Axis Direction) or After (Positive Axis Direction).
Click Add New Plane.

Other Plane Refactoring tools:

Edit: choose planes and control nodes from a tree, with Select All, Deselect All, Expand All and Collapse All.
Delete Plane: removes a plane. It's disabled when deleting the plane would leave the volume open.
Undo / Redo: reverses or reapplies the last change to the volume.

Click Save to keep your changes. You can't edit parameters while the volume has unsaved changes.

Reuse or manage volumes¶

To…	Do this
Reuse a volume from another Part	Click Import Volume and choose the Programme, Part Library and Part it belongs to
Open an existing volume	Choose it from the Part's list of volumes
Rename a volume	Edit Name, then Save
Delete a volume	Delete. A volume that's in use in a Run can't be deleted
Close the volume	Deselect Volume

A volume that's been used in a Run opens as Viewing Volume, read-only. To change it, import it as a new volume.
