Understanding the projection methods

The Attachment toolset provides three tools for creating attachment points. The tools provide convenient methods for producing points, such as following an edge, reading the coordinates of each point from a file, or spacing points along a line. However, in some cases it may be easier to define the attachment points in one location and project the points onto a desired face. Therefore, Abaqus/CAE provides projection options as a method of positioning attachment points on a face.

The Attachment toolset provides the following techniques to create attachment points by projecting points onto the desired face:

  • Project each point to its closest face.

  • Choose the start point and end point of a projection vector. Abaqus/CAE projects each point along the vector and creates an attachment point where it first intersects with a face.

Figure 1 illustrates the two techniques for projecting points onto a selected face.
