Known point change coordinate

[Anonymous]

I have a curb and gutter drawing in autocad. It was drawn using an unknown coordinate system (most likely started at zero, zero).

I would like to change the value of the coordinates to match my Surveying coordinate system).

I have a known point in the drawing, let’s say a building corner, with a coordinate 300, 200. And I would like to change it to 364112, 107765. And subsequently have all the other points change as well.

How do I do this. I know enough about autocad to be dangerous, so your step by step is helpful.

Hi,

MOVE command will do that . try to understand the issue after reading this link . >> Click <<

Command: m MOVE
Select objects: Specify opposite corner: 1 found

Select objects:
Specify base point or [Displacement] <Displacement>: select here your known building corner
Specify second point or <use first point as displacement>: @364112, 107765

Now all of your selected objects will move to the new coordinates that you need and choose .

If I understand correctly what the OP is after, that should be either:

A)  if Dynamic Input is on  [DYNMODE System Variable] in versions that have it, #364112, 107765, or:

B)  if Dynamic Input is off, or in versions old enough not to have it, just 364112, 107765 [without prefix].

Another thing the the OP needs to think about is orientation -- eg while one known coordinate will get you to the correct spot at one location, there's no reason whatsoever to assume that the X-Y directions are the same between the two schemes.  Best to have a minimum of two know coordinated, and to rotate after moving.  North is only occasionally North after all
