You'll find that when constructing helix-shaped objects (with the Sweep command) this is an especially convenient way to see the results of the radius, pitch, and angle values as you set them. For example, you can change the height and the angle of a tapered extrusion.
When you select a VectorWorks' 3D object, its dimensions will display in the Object Info palette. The Add and Intersect operations are performed without any further action from you, but the Subtract operation displays a dialog box for you to use when specifying the object whose volume the others will subtract from. You must preselect at least two objects before you invoke the commands. Although-despite their names-the operations do work with surface objects, you will generally use them on 3D objects that are completely enclosed by a unified surface. The names of the VectorWorks commands for the Boolean operations are Add Solids, Subtract Solids, and and Intersect Solids, and they are accessed from the Model tab of the screen pull-down menu. You can use the Boolean intersect operation to create a 3D model from a multiview 2D drawing. These objects are then moved together, as shown in panel C, and the Intersect operation creates the 3D model shown in panel D.įigure 1. The outline of the part in each of the three drawing views shown in panel A of the figure are extruded to create the three 3D objects shown in panel B. It can, for example, transform 2D drawings into 3D objects, as shown in Figure 1. Usage of of Intersect is not so obvious, but it is a very handy operation. Usage of the Add and Subtract operations is straightforward because the Add operation is somewhat similar to fusing components together and Subtract is similar to drilling holes or milling away portions of a base part. Subtract removes the volume that one or more 3D objects share with a specified 3D object, and Intersect leaves only the volume that is shared between two or more 3D objects. The Add operation combines the volume of two or more 3D objects.
#Vectorworks 3d modelling how to#
This one column will describe how to combine and modify those 3D objects to create complex 3D models.Īs does virtually every 3D modeling program, VectorWorks supports the three Boolean operations-Add, Subtract, and Intersect.
#Vectorworks 3d modelling series#
This is the third in my series about the 3D features of VectorWorks, an $895 2D drafting and 3D modeling program from Nemetschek North America that runs on computers using either Mac or Windows operating systems ( My previous column (" Creating 3D Objects in VectorWorks") focused on the VectorWorks tools, which are initiated from buttons on tool palettes, and its commands, which are invoked from screen pull-down menus, that create basic 3D objects.
