Entering bars
Bars are entered using the tools available in the "Bars" group of the top toolbar, within the "Geometry" tab (in the "Structure" tab).
Bar
The "Bar" option is used to insert a new bar into the structure.
Defining the properties of the bar
In the "Properties - New bar" panel that appears, the main button is used to "Describe" the section.
Users can modify the "Angle" and, on the right, the layout with respect to the input line.
The table below shows the "Sections used" previously in the job. They can all be selected directly.
Entering a bar into the work area
Each bar is defined by its start and end nodes, so to enter it, two points must be selected with the left button in the "Work area".
These can be nodes previously entered using the options in the "Nodes" group or points in space yet to be determined.

| Users are provided with various aids for entering these points in the work area In the "Drawing" menu, users can select the “References” option and activate the "Show grid" and "Reference lines" options. To activate the snaps of other elements already inserted in the model, the "Object Snap" option is used. Users can also click on the "Allows for dimensions to be defined upon entering each element" option to write the value of the "Length" of the bar when entering it. On the other hand, the "Orthogonality" and "Polar tracking" options force the direction of the bar at the moment of insertion. If desired, users can also use "Coordinate entry", and if a template has been entered in the program, the "Template object snaps" are used. These options are available in the top right toolbar. |
Inserting consecutive bars
After entering a bar, further bars can be entered by left-clicking on other points. To finish entering bars, click the right mouse button.
Generating nodes at crossbar cut-off points
When entering two cross bars, you can keep the "Generate nodes at intersection points" option activated in the "Bars" group so that the program automatically generates a node defined as an inner link at the point of contact of the bars.
If kept deactivated, the bars will be unlinked in the model and a node will not be generated at the intersection point.
Delete
The "Delete" option is used to delete a bar.
To do this, make an individual selection by left-clicking on each bar or draw a selection window. When drawing from left to right, this window selects the bars that are completely contained within it. When drawing from right to left, the bars that are completely or partially contained within it are selected. The selection of a bar can be carried out by left-clicking with the mouse while holding down the "Shift" key.
By pressing the right button, the program will delete the bars.
| Note: |

| The nodes formed at the ends of the deleted bar will remain in the model. |
Move end
The "Move end" option is used to change the position of one of the end nodes of a bar. To do this, select the node by left-clicking on it and then click on its new position.
