Copy with base point-Paste to original coordinates

[Anonymous]

Hello all,

I am working as a CAD drafter and I want to know that why sometimes "copy with base point and paste to original coordinates" does not work. Recently, I was working on one project and I wanted to copy one riser going up from level 1 floor plan to the exact same location on level 2 floor plan. I used copy with base point with 0,0,0 and when I paste it on 2nd floor, it went off the drawing. Interestingly, on another project this procedure was working fine. So, I would like to know what is the primary reason of this thing? What should I do or what settings should I apply first before starting on any project so that whenever I want to use  "copy with base point and paste to original coordinates", it will work. Currently, I am struggling with this and since I am not able to figure this issue, I have to measure dimensions off the grid lines before placing any equipment or riser and this is taking too much time. Please advise.

Why not use a base point from the building grid line as you say.  You didn't say if it was from two different drawing. There could be a user coordinate difference if two drawing. Also check your units if the drawing(s).

Hi,

>> when I paste it on 2nd floor, it went off the drawing.

i suggest to check the insertion base point for the current drawing from BASE command .

Once you "copy from basepoint" you purposefully give up on AutoCAD tracking the original coordinates since you told it to do so by manually selecting another origin point.

If you want AutoCAD to keep track of the original coordinates then you need to just COPYCLIP the object(s) instead. If you don't like that result, that simply means your two DWG files are not perfectly positioned identically. You need to fix that problem yourself. See other posts on how to do that (BASE command).

If you want to use "COPY FROM BASEPOINT" then you need to commit to the placement location yourself.

I have to contradict some others' suggestion that you involve the BASE command.  That will not help.  That only sets a location within the current drawing that will be the insertion base point of the current drawing when you INSERT it into another drawing.  It does not affect the coordinate locations of anything in the drawing, so it will have no effect on the results in PASTEORIG.  What you would need, if you want to use PASTEORIG, is to ensure that the elements in both drawings lie in the same relationship to the 0,0 origin.

But if you get them positioned the same that way in both drawings, I agree that if you want to use PASTEORIG, don't use COPYBASE but rather just COPYCLIP.  Or use COPYBASE with a base point at some meaningful relationship to the selected objects, and use just PASTECLIP and give it that same location in relation to objects in the target drawing.
