You can even go as far as keeping this all procedural. Set Volume essentially lets you set the initial state of the lattice. With the updated booleans in max 2017/2018 (not sure right now) you can also put a Editable Spline modifier on top. This lets you fit the lattice more precisely to irregular-shaped objects, giving you finer control when deforming. Choose the Lattice sub-object level, and then use any of the transform tools to adjust the lattice volume relative to the geometry.Īt this sub-object level, the deformation lattice control points turn green, and you can select and manipulate control points without affecting the modified object. However, you can position, rotate, and/or scale the lattice box so that it modifies only a subset of vertices. The pieces were then exported as STL files and imported into Autodesk Inventor using the Mesh Enabler for Inventor plug-in available on Autodesk Labs. The lattice volume defaults to the bounding box of the selected geometry. The overall shape and surface texture of the speaker enclosure was designed in Autodesk 3ds Max (using topology modifier, bend and wave modifiers, and FFD lattice). Moving or scaling the lattice so that only a subset of vertices lies inside the volume makes it possible to apply a localized deformation. When you first apply an FFD, its lattice defaults to a bounding box surrounding the geometry. If Auto Key is on, doing so animates the lattice. If the Auto Key button is turned on when modifying the control points, the points become animated.Īt this sub-object level, you can position, rotate, or scale the lattice box separately from the geometry.
You can use standard transformation methods with the control points. Manipulating control points affects the shape of the underlying object. At this sub-object level, you can select and manipulate control points of the lattice, one at a time or as a group (select multiple points using standard techniques).
