Fitting pins at the ends of the bars
The pins at the ends of the beams are created using the following option, available in the "Beams" section of the top toolbar, within the "Properties" tab (under the "Structure" sub-tab).

Pins
The "Pin" option allows you to add pins to the ends of the bars, enabling full rotation in all three spatial directions, including rotation about their own axis.
When you click on the option, a pop-up window will appear asking whether you wish to make a "Single" or "Multiple" selection.
If an "Individual" selection is made:
- When you click in the middle of a bar, the program inserts pins at both ends.
- If you click on one end of a bar, the pin is only inserted at that point.
- To remove the pins you have inserted, click again on the centre or end of the bars.
If a "Multiple" selection is made, the program will add or remove pins at both ends of the selected bars.
In the model, the articulated ends are represented by blue circles.

| The "Pin" option does not allow you to define any partial fixity. To do this, you must use the "Fix" option in the same group of options. |
