AutoFEM Analysis Multi-volume bodies | |
Mode Multi-volume bodies reflects multi-volume bodies if any are in the study. The multiple-volume body is the term meaning the AutoCAD object which consists of several non-contacting volumes. Multi-volume bodies are treated by AutoCAD as a single object. In versions until 2.5, AutoFEM Preprocessor requires only the one-volume nature of solid bodies involved in the study, i.e. one closed volume in the 3D space must correspond to a single body. In version 2.8 and following, this restriction is removed.

Multi-volume bodies are formed, e.g., when using copying by massive in AutoCAD (use the AutoCAD command EXPLODE to separate the massive into separate bodies), and also can be obtained when a body is created with the help of Boolean operation (in this case, for the division of the multi-volume body, the AutoCAD command SOLIDEDIT/BODY/SEPARATE is used).
In addition, the multi-volume bodies may emerge in the process of automatic correction of the model’s intersections by the command of study creation. Appearance of the multi-volume bodies post automatic correction indicates significant inaccuracy of the 3D modelling of the real structure and requires correction using AutoCAD tools.
Appearance of the multi-connection body in the process of intersection corrections evidences errors in the 3D modelling process
