There are supports at the bottom lines of all walls. To allocate supports, open the Types for Lines folder in the navigator and double-click the 1 Hinged item.
For a hinged support, the translational degrees of freedom are restrained in the directions X, Y, and Z so that the line is supported in those directions. There is no rotational support about any axis.
To assign this type of support to the bottom lines graphically, click the
button.
Draw a window from left to right which includes the bottom lines nos. 1 through 3. Make sure that no other lines are fully contained within this window (if necessary, rotate the view). When you have selected the lines, click OK.
Check whether the correct line numbers are shown in the 'Assigned to Lines No.' area. Click OK to allocate the supports.
