Deform a Part¶
Apply one of a volume's parameters at a chosen magnitude, preview the result, and create it as a new Part.
Before you start
The volume needs at least one parameter. See create deformation parameters.
Load the volume for deformation¶
- Open the Part's volume in the Morphing panel. See create a deformation volume.
- Click Deform Part. Bramble works out where the Part's surface sits inside the volume, which shows "Mesh node location in progress...". This can take a while for detailed geometry.
- Open the Parameter Deformation tab in the sidebar and click a parameter.
Preview a deformation¶
Drag the parameter's slider. The viewer shows the deformed geometry.
To help you judge the result, open Morphing Visualisation Tools:
| Option | Use it to |
|---|---|
| Live Geometry Update | Update the geometry as the slider moves. Turn it off for large Parts: only the volume moves until you create the Part |
| Smoothing Applied | Preview with or without smoothing. Turn it off to check which nodes a parameter moves. The created Part is always smoothed |
| Sharpness Factor, Deformation Factor | Tune the smoothing (both default to 1). See smoothing |
| Deformation Heatmap | Colour the surface by how far it moved. It shows the maximum and mean deformation |
| Simplify Mesh during deformation changes | Keep the preview responsive on large Parts |
| See Original Part | Overlay the undeformed Part for comparison |
Create the deformed Part¶
Click Create Part. Bramble shows "Deformed Part Creation Started", then "Creation Successful".
The new Part appears in the same Part Library (folder) as the original, named
<part name>-<volume name>-deformed-<number>. The original Part isn't changed. On the Parts page, switch on
Show deformation status to see its progress, or any warnings, in a Deformation Status column.
Chain several deformations¶
To apply more than one parameter, one after another:
- Set the first parameter's slider away from its starting value, then click Create Chain. The Chain Deformation tab opens.
- Click Add Parameter to add the next deformation. The menu also has Create New Parameter.
- For each entry, enter its Magnitude and click Apply.
- Drag the rows into the order you want. Each deformation is applied to the result of the one above it, so order changes the result.
- Click Create Displayed Part.
Each chain row also lets you: - show or hide the deformation - pick a colour for its origin and axis markers - Edit Parameter in chain - Remove Parameter from chain
Hidden deformations aren't created
Only the deformations that are visible when you click Create Displayed Part go into the new Part. At least one must stay visible.
To step through the chain as an animation, use Movie Visualisation: - Step Previous, Play and Step Forward - Delay (ms), from 250 to 10,000 - Reset Visualisation
Cancel Chained Deformation leaves the chain without creating a Part.
Move control nodes directly¶
For a one-off change that doesn't need a parameter, open the sidebar's Morphing tab. There you can move individual control nodes, edges or planes with position sliders, in millimetres, and then click Create Part. Reset Changes puts everything back.
Finish¶
Click Stop Deform Part and confirm to leave deformation mode.
