Individual dimensions for text and other objects within the sign panel do not display in OpenRoads SignCAD. Only the overall panel width and height dimensions are shown.
The text and other objects in the sign panel are placed over the sign panel but are not actually in the sign panel and that is why only the overall panel width and height dimensions display in OpenRoads SignCAD. If the sign panel is moved on the workspace, you will notice that the objects do not stay with the panel.
When an object is selected, moved and positioned over the sign panel, then the panel will blink indicating that it recognizes the object. Once the left mouse button is released and the object is placed in the sign panel, then the individual width and height dimensions for that object will display.
