Relative Placing Point
When this function is selected, a drawing is positioned on a drawing sheet according to a relative reference point. If changes are made on the building model that affect the drawing, the drawing is positioned on the drawing sheet after the update thus that the selected reference point is related to the changed drawing and remains at its previous position on the sheet.
In the example, the center point of the left edge of the drawing area has been selected as the reference point of the drawing. The drawing has been positioned on the sheet using relative positioning. The building model is changed thus that the drawing is enlarged. After the update the reference point is related to the changed drawing. The location of the reference point remains unchanged.
