Selecting the Assign-Columns-Size command causes the Assign Size dialog box to be displayed. From this dialog the engineer can assign new sizes to any lateral columns. Select the appropriate material from the material box at the top of the dialog. Select the appropriate size from the size box. For concrete and other materials the sizes displayed are those sizes created by the user in the RAM Modeler. For steel sections the sizes shown are based on the member type (column) and the currently selected master steel table (refer to the RAM Manager). Note that only columns of the material selected in the dialog can be assigned the size selected.

After a size is selected the engineer can assign the size to a single member (click on Single), to multiple members (click on Fence) or to all members (click on All). If Single is clicked the dialog will close and a target cursor will be made available. Click on each member to assign the size to. If Fence is clicked the dialog will close and a fence cursor will be made available. Click and drag a rectangle around all of the members to assign the size to. Note that sizes are only assigned to columns comprised of the same material selected in the assign dialog. To return to the dialog to select a different size to assign click on the right mouse button.
