Better design starts with better software.

The latest release of NX software delivers a robust set of new tools and significant enhancements to existing
functionality. The goal is to help you design, test and manufacture your products quickly and with fewer errors than ever before.

NX 11 introduces capabilities for convergent modeling, rapid manufacturing, with improved annotation, drafting and documentation, and rendering. Active Workspace in NX 11 is built around these items to provide seamless access to PLM capabilities right within NX.

The following article explains the new function "Swept Volume".

Swept Volume

  • With the Extruded Volume function, via a Boolean operation of type “Subtract” or “Intersect”, a swept body can be created by dragging a "tool" along a path (2D or 3D).

  • The tool must touch the tool path.

  • The tool paths can be planar, not planar or self-tapping. The paths must be connected to each other and cannot be collinear to the tool axis.

  • The tool must have a cylindrical shape.

This is how it works:


1. As first step, you have to select the tool body.

For the tool body the following must be considered:

  • It must be a single volume body.

  • It may not have any through-holes, blind holes or internal cavities.

  • The tool axis must intersect the path within the tool body.

  • It must be generated using analytical geometry.

  • It must be generated cylindrically or rotating around an axis.

2. In the second step, you have to select the tool path. The tool path is a 2D curve geometry.

3. The third step is then to select the corresponding tool path orientation.

Two different options are available:

  • Parallel to Tool Body: Holding the extruded body parallel to the axis of the tool body.
  • Normal to Path: Allows an orientation of the extruded body along the normal of the tool path relative to the tool body axis. The orientation can be locked by specifying a vector.
