Hello Everyone,

In Abaqus/CAE, Attachment Points are highlighted as "Wire edges”.

At top level there are four types of topological entities in a geometry kernel: Solid Body, Sheet Body, Wire Body and Point/Acorn Bod. All these bodies may internally have Cells, Faces, Edges and Vertices.

The geometry kernel which is used for CAE is called ACIS which doesn't have the concept of Point/Acorn Bodies. Solid Body is called Solid Cell in CAE, Sheet Body is called Shell Face in CAE, and Wire Body is called Wire Edges in CAE but nothing in CAE corresponds to Point/Acorn Body. So there is no way to represent a Point (say for e.g. Attachment Point in our case).

So whenever a Body for attachment points is to be created, a zero length Wire Body with two vertices having coordinates as that of the attachment point is created (as per advice of ACIS).
