Learn how to add analytical nodes in your 3D model.
You can automatically create analytical nodes for each beam end using the
(Create nodes for entire model) command, located in the Extended Modeling tab 
Nodes panel.
When using this command, existing nodes will be deleted and new ones will be created. The application warns you about this.
If you choose Yes in the warning dialog, the analytical nodes will be created at each beam end.
You can also create individual nodes using the
(Create node command), located in the Extended Modeling tab Nodes panel.
The command requires:
- The location on the input element (middle or end).
- The input element.
- Pressing Enter to stop the selection process.
- The insertion point of the symbol (node position).
Add Beams to Nodes / Remove Beams from Nodes
You can manually add beams to an analytical node or remove them, using the
(Add beams to node) and
(Remove beams from node) commands, located in the Extended Modeling tab Nodes panel.
Regardless of which of the two commands you use, you need to first select the beam and then the node.
