A group of nodes will be assigned the same connection. The connection assigned to a group of nodes will read from the BIM project the bar forces of all the nodes in that group. The combination filter obtained from "Generate from BIM model" is carried out by adding up the combinations of all the nodes.

The options available to generate these groups are as follows:

• Group
  Allows matching nodes to be grouped together. When a node is selected, all those that match are highlighted in yellow.
• Ungroup
  Allows previously grouped nodes to be ungrouped.
• Generate
  Generates nodes and automatically groups matching nodes.
