Compress nodes: Remove nodes, which are close together

This command compresses the nodal data by eliminating nodes, which are close (within a given tolerance) together. Before compressing all related nodes can be checked graphically by pressing “Plot”. Pressing “Apply” causes the compression to be done.

Following dialog shows the available options:

Element selection

The nodes of all selected elements are considered.


The tolerance for nodes to be merged into one node must be given. Nodes with a distance lower than this value are merged into a single node. When reading a structure from AutoCAD compression is done automatically.


Nodes within given tolerance eps are marked by a colored symbol

Individual nodes

Nodes within given tolerance are marked. Afterwards two nodes at a time have to be selected graphically which are merged into a single node. Canceling is done by right mouse button.
