Lisp to dimension between two center points

[Ramees]

Hello again CAD wizards,

 

So heres the thing i want to do.

 

 

 

 

I have to dimension 800 such points in a drawing file. So what I want to know is that is it achievable using auto lisp. All I need to do is create an aligned dimension from the center of the Yellow hatched Circular object( Which is by the way created as individual blocks) to the center of the magenta colored circle.(All the magenta circles are part of large Single Block)

 

Any help in creating this hugely appreciated. I really dont know if this is a rather simple or a complex task as I am a noob to autolisp;)

How would it work differently than just using aligned dimension? Is the distance between each pair of yellow and magenta circles the same?

[Ramees]

Actually Its not the same,that is what needs to be found out. Magenta represents the design position of a pile and Yellow represents the actual position of a the pile. Dimension is required to mark the deviation from the original

Perhaps if you searched for "deviation" or "as built", you could find what is already on the forum.

 

In the meantime, this thread might be able to help you

That Wont Solve my problem because it gives the deviation in vertical and horizontal direction . However I could Extract the design coordinates using the data extratction option in autocad. So right now I already have the design coordinates and as built coordinates and I know the distance. But I neeed to show it in the drawing also So it there is way to place an aligned dimension between the two coordinates connected from a csv file or something

Via lisp maybe explode the master block or others smarter than me get the centre point of all circles in the block, you then get all the other circles step through them and do a small window search with a tolerance so as to only get the two objects, then its easy to do a DIm AL Pt1 Pt2 and so on. NO dwg so no real help.
