Spot Coordinate

319 Views, 2 Replies

After specifying the shared co-ordinate of a project all the reference co-ordinates of linked drawing are matched with the project. But when we rotate the true north all the co-ordinates are getting mismatched with the reference drawing. How it would be possible that the co-ordinates remain same after rotating the true north ?

When you rotate true north, if you move the true north rotation origin to overlap the project base point the location should not change [other than the angle to true\project north] as long as you graphically click the rotation points or enter the “CCW Rotation Angle”.  
Otherwise if you rotate the entire view the coordinates will slightly shift:
Otherwise you could rotate true north first and then specify the coordinates as needed.
Thank you,

Thanks for your feedback.

 

By this process only one co-ordinate will remain same after rotating the true north and it is necessary that the point should be the base point for the rotation.

 

But is this possible that after rotatating the true north of a project at certain angle the shared coordinates (of 2 or more than 2 points) remain same. We are attaching a jpg. If yes then how?
