Deformation

This commands allows to deform a shape or a surface. Available deformations are:

Creation stages / Use:

Click on the icon or select the Shape > Other operations > Deformation... command from the drop-down menu.

Select the shape or surfaces to deform.
Select a deformation if it has been created before, if not click on "+" to create one.
If surfaces have to be deformed, select surfaces to deform. If we consider as example a sheet metal part to be unfold, the 2 faces on the bend (the inside and the outside of the bend) and the 2 lateral faces are all faces that have to be deformed. All the faces of the flange to unfold are faces to be transformed. In this kind of case, lateral surfaces have to be separated for each group of surfaces. You can use the Surface > Imprint command.
Validate by clicking .

The initial volume of the shape is not preserved after deformation.

Available Options:

Face by face:

This option allows to use another mechanism for calculating the deformation when the overall deformation fails.

Detect faces to exclude: This button allows to automatically excludes the problematic faces. These faces will be added to the list of faces to exclude, this list can be completed manually.
Unsew: Activating this option TopSolid will create as many surfacing shapes as faces composing the shape to deform. These surfaces are available in the Shapes folder of the entities tree. Without this option TopSolid will create a unique surfacing shape result of sewing of all faces at the given tolerance.
Create boundary edges: Because this deformation mode allows a surfacing result, it is interesting to recover the boundary edges of exclude faces to help the construction of new surfaces. A sketch operation is then created in the operation tree.


Original shape with flexion deformation	Preview and result of the flexion deformation. The front cylindrical face, the top face and 2 side faces have been automatically excluded to allow this deformation.

Rebuild blends:

If this option is not activated, the fillets of the part will be deformed as well. The deformation can generate a loss of tangency or a punctual change of the radius at some points. When checking this option, fillets are "removed" before deformation, then rebuilt after deformation.


Torsion without rebuilding blends option	Torsion with rebuilding blends option

Faces to deform:

If you have chosen some faces with the Faces to deform option, this dialog allows you to select the faces that will not be deformed but moved only.

This could increase performances on complex shapes.

Example of torsion with faces selection, the 2 yellow faces are moved only

Modifications:

Each modification can be done using the popup menu from the operations tree.
