M. To detect and remove zero length members
A zero length
member is one of the undesirable consequences of having duplicate nodes in the
structure. A member connected between duplicate nodes, which have the same
(X,Y,Z) coordinates, will have a length of zero (or nearly zero).
- On the Utilities ribbon tab, select the tool in the Geometry Tools group. The Zero length beams dialog opens.
- (オプション)
Type a different tolerance in the
Enter Tolerance field.
Since duplicate nodes can be two or more nodes separated by any user-defined distance, zero length members too can be defined as members of any user defined length. This distance is the tolerance used in the process of detection.
-
Click
OK.
If no members of zero length are detected a message is displayed.
If one or more zero length members are detected, the Detect Zero Length Member dialog opens.
- Select a zero length member in the list and then click Delete to remove the beam.
- Repeat Step four as necessary until all zero length members are removed.
- Click Close.
