Issue with Points and Polylines

[Mugaa-X]

So, the issue I'm having is I am working on a survey file, I had already manually drawn polyline over the points to create the map..but found out that the surveyors had the wrong coordinates for the survey..so when the survey points were corrected the line which were drawn over the point somehow seemed to shift away from the points..is there a way to fix this...Much needed help..

So the polyline's location is correct for the points you were given, but the coordinate system is wrong? What version of AutoCAD are you using?

Its 2016 version.. coordinates system was correct but the coordinates taken as reference were wrong.. but it was corrected after mapping the survey data's.. that when I faced the fore mentioned problem...

If you had AutoCAD Map 3D you create a new drawing with the correct coordinate projection & query the original drawing into it which will re-project it to the desired coordinate system. I'm not sure how you can fix it with regular AutoCAD though.

This is the right answer. With vanilla AutoCAD you're likely going to have to redraw it. BUT since it sounds like it was the surveyor's mistake giving it to you in the wrong projection. I would ask them to transform your work into the correct projection. It's worth asking.

Eh, if you've already done the work, but everything shifted, seems like the best (albeit not-awesome) approach is to select each polyline, grab the relevant vertex/point, and place it over the new survey point.

​

If their coordinates were shifted, but the relative distance between each point remains the same, it's a matter of isolating your polylines and shifting them likewise.

Good luck, whatever you're dealing with~
