The Panel Dimension shows the number of Formwork components on a Wall. Handset Designer automatically draws Panel Dimensions and places them on the right or left side of the Wall (refer to About Wall Orientation and Direction for more information on right and left). To draw a Panel Dimension, simply highlight right-click the Wall and select either the right or left Panel Dimension. Per convention, the Panel Dimension does not have any indicator of any panel heights or stackups.
In the Formwork Design tab of the Formwork Options dialog, there are two options for displaying the Wall length and height on a Panel Dimension. Checking these boxes allows the height and length of the Wall that's selected to be shown on the Panel Dimension.
