For labeling doors and windows in section/elevation. This is completely different from the dimension marker used in plan.
It is intended to be used as an associated label.
How about a quick review of associated labels. To place an associated label, select the element, in the window you want the label, and Check 'label Elements' in the Info Box. Which label will be placed? Ah. Each tool has default label settings, which are configured in the Label settings dialog. For each tool you want to label, highlight it in the list at the top and choose the appropriate label from the top right flyout. This is also where you set the pen, layer, and other attributes of the label. Remember that labels can have a different layer than the elements they reference, and they usually will.
For doors and windows, starting today, set the label tool to use Door-Window Label JM9.
It draws a hexagon for windows and an ellipse for doors. It knows the difference! If Auto Size is on, the window tag will be 5/16" and the door tag will be 3/8". If these don't meet you needs, turn Auto Size off.
Once the label is placed, move it where you want it. (A method to control where labels pop up remains elusive.) Place the label on a sash with no divisions, or to the side of the window/door. Try not to obscure the design of the window/door.
