orientating rotating a drawing

[timurphy]

Hi all

 

Im running autocad 2004 and am having trouble rotating/orientating a drawing in model space. i have two fixed control points that are in the correct position and an arbitary survey that has also has two control points which are 'floating'??

 

i need to recify/position the drawing with the two points to the two fixed controls i already have in the drawing. simply rotating the the drawing is not accutate enough.

 

i basically need to drag point A to A1 and B- B1 with all the accompanying points

 

sorry if im not explaining very well

 

any help much appreciated

 

cheers

It's been a while since I used 2004 but is there an ALIGN command in that version? If so, that would help immensely.

 

I'm baaaaack.

 

Yep, there sure is. Confirmed it myself.

 

Type ALIGN at the command line and follow the prompts.

As mentioned, use the ALIGN command and that should work. Using the 'scale' command within the ALIGN command (scale objects based on alignment points) will actually 'scale' your arbitary survey. This will cause the survey to become inaccurate as it will actually change the distance between the points vs. how they are in actuality (ie: distance on actual site). As you mentioned, the rotate command isn't sufficient, but it technically should be since your control points should match the survey regardless, if there is a difference (ie: distance from A to B should equal distance from A1 to B1), by using the 'scale) sub-command, you will be inputting error into your project.

 

I don't have enough information to know for sure what the use of your drawing is, there are instances where a person possibly should 'scale' a survey but in reality, you should never do that. As I mentioned, all depends on what you are working on I suppose.
