Defining Beam Sections - Columns
Next, we wish to assign a UC (column) section type to the first row of columns.
To do this:
1. Open the "Add" tab in the "Properties | Beam Sections" dialogue box.
2. In the 'Number' drop-down box, '5' should be automatically generated.
3. Select the 'Type', 'Family' and 'Size' of column required. In this instance, the options chosen are 'I Sections', 'UC' and '356 x 368 x 129' respectively (the preview window will display the chosen section type).
4. Select the number of (FE) divisions to use in the beam (in this instance,5 in both the local X and Y directions is sufficient).
5. Click the 'Add' button to enter the new section type on to the database.

6. Click the "Attach" tab to assign the new section type to the required elements.
7. Select the required section type (i.e. '5') from the drop down list.
8. Choose the members that require the 'column' cross-section by clicking them on the main screen.
9. Click the 'attach' button.
