|
|

|
This tool generates an offset surface from the target object using `OpenVDB <https://www.openvdb.org/>`__.
|
||||||
|
It is useful for hollowing out a model for 3D printing, for instance, to save material and/or speedup print.
|
||||||
|
It is also possible to create a thin-walled mold for the object, when using an outside offset surface.
|
||||||
|
|
||||||
|
The target object must be a closed surface to allow for an inside offset surface, but not necessarily manifold.
|
||||||
|
On the other hand, outside offset surfaces can be created even for open objects.
|
||||||
|
|
||||||
|
Offset Direction
|
||||||
|
Where the offset surface is created relative to the object. An *Inside* surface is useful to hollow out the the
|
||||||
|
target, while an *Outside* surface can be used to create a thin-walled mold.
|
||||||
|
|
||||||
|
Offset
|
||||||
|
Surface offset in relation to the original mesh.
|
||||||
|
|
||||||
|
Voxel size
|
||||||
|
Lower values capture finer details but increase processing time and memory usage. Too large a value may lead to
|
||||||
|
the offset surface intersecting the original object.
|
||||||
|
|
||||||
|
Hollow Duplicate
|
||||||
|
When unchecked, only the offset surface is generated. When checked, the tool generates a hollowed out copy
|
||||||
|
of the target.

Rotates the object so that the selected faces are parallel, in average, to the XY plane.

Face Areas
|

Take into account the sizes of the selected faces, so that larger ones contribute proportionally more to
|
||||||
|
the orientation than the smaller ones.
