Tips How to Rotate the Drawing on scale position

Posted on Updated on

In Construction Engineering for Oil and Gas Company shall always have liase to Drawing engineering. Of course, with AutoCAD software as the main software of it. one of the most element on each drawing engineering is scale. Scale use to describe the true object position on the surface.

To rotate your drawing on scale position as UTM coordinate (Projection Coordinate System) with following :

  • Please aware the position of the original north as shown picture below. Prior to check and set up the drawing units in meter unit as the international unit system

  • Check the distance between UTM coordinates grid (projection coordinate system) on the drawing. For example, the horizontal scale is 1 : 2500, it means the distance value is 250 meter
  • Make the help line to rotate the drawing position to be the true north, and type command line :
    UCS (enter) – e (enter) – tick the help line (as the original north of drawing) to be the cartesian coordinate system.  See the picture as below

  • Type the command line as below
    Ro (enter), all (enter), UCS (enter), e (enter). And the picture as below

  • Move the drawing base on the UTM Coordinates (example : 549750, 9957250), type the command line as below
    M (enter), All (enter), right click your mouse, put the mouse on the UTM coordinate grid, input the UTM coordinate value (enter)

then, continue type the command line :

            UCS (enter), E (enter), Pu (enter), click “Purge All” to clean drawing

  • Check several coordinate value to make sure that the UTM coordinate grid value already on scale

Note :

  • To make the True North appropriate to the Original North as shown the drawing, please use the command line ; UCS (enter) —> E (enter) —> View —>3D Views —>Viewpoint presets —>tick Relative to UCS —>input XY Plane 90 —> Set to Plan View —> OK
  • Then, re-check several coordinate value to make sure that the UTM coordinate grid value already on scale, If the UTM coordinate grid value is still missing, use the command line Circle (C), input the UTM coordinate value and move the drawing with.
