There are many ways to create a model, and the most efficient and effective combination of object types and editing methods varies widely depending on the end goal of the design process. The 3D modeling tools and commands can be combined to create complex objects step by step. Several commands, primarily but not exclusively available through the Modify > Convert commands, convert one kind of object into another, for different kinds of manipulation using the other tools and commands.
Scripts can manipulate a large number of objects efficiently. Marionette scripts can be used to create or modify many kinds of 3D objects, including solid objects, meshes, plug-in objects, and site models. Visual scripting with Marionette builds networks of sequentially performed actions, to define an object’s size, shape, texture, and much more. It is often best to convert a mesh into a different object type to edit more effectively, or to simplify a mesh to reduce the file size (see Simplifying mesh objects). However, meshes are very “expensive” in terms of computing resources, and they are difficult to edit efficiently. Meshes are useful in Vectorworks, to import models from other programs and to help convert objects of one type into another type. This allows for the creation of curved complex shapes and other more supple manipulations. Depending on the iteration setting for the model, the cage mesh is not necessarily identical to the object’s shape rather, changing an edge, face, or vertex of the cage mesh can affect the underlying shape indirectly and more subtly. Starting with a geometric subdivision primitive object, you manipulate a polygonal cage mesh to sculpt the desired shape. Subdivision modeling is a very powerful and flexible method of creating objects that have an organic or free-form shape. Surfaces can be converted into solid shapes using features such as the Shell Solid tool and the Stitch and Trim Surfaces command. Use NURBS surfaces and associated tools and commands such as the Loft Surface, Extract, and Project tools and the 3D Power Pack command suite to create non-rational, free-form shapes such as drapes and other flowing objects, and then use weighted vertices to “pull” the surface into shape. Because generic solids use far fewer computer resources than other solid objects, you may choose to convert an object to a generic solid once its final form is achieved and you are confident no more edits are needed, to reduce file size and improve performance. By contrast, generic solids are scrubbed of all history.Īny solid object can be converted to a generic solid object, and some solid operations automatically result in the creation of a generic solid.
Many solid objects also have a nested editable history (see Editing solid object history). Several tools and commands, primarily in the 3D Modeling tool set and in the Modify and Model menus, can create and reshape solids. Solid objects, which contain a volume, include extrudes (regular, tapered, multiple, and along path), sweeps, shells, fillets, chamfers, solid primitives (spheres, cones, etc.), solid additions/subtractions, and others. These can then be converted into other objects, like surfaces and solids, to form more complex shapes. Objects such as NURBS curves and 3D polygons can create primitive shapes in 3D space by precisely manipulating the vertices and contours of the objects (see Creating NURBS curves and Creating 3D polygons). There are generally multiple ways to create any model, but using the right objects, tools, and commands in the right sequence can both increase efficiency and improve results. Vectorworks includes a flexible combination of tools and commands to create and manipulate 3D models. 3D modeling in Vectorworks provides techniques to meet a range of design needs, including architectural details, custom furniture, and sculptural objects at a large or small scale.
