Z Axis orientation issue

[Anonymous]

hi all,

Please find attached file, i am facing problem with(actual drawing is having lot of lines, this is sample).

I am trying to change elevation of polyline, but doing so results in movement in XY plane

Trying to snap center of arc, but snapping away from center.

(see revclouded area)

tried to flatten it but thats not working, as lines move in XY plane

tried to purge, audit, copying everything in new file that also not working

tried to save in dxf and very old version, that also didnt work

tried changing , ucs and all...

please help in flattening this drawing without redrafting and dislocating polyines.

Hey @Anonymous,

Please find attached drawing. I don't know exactly whether this is what you wanted.

Here is what I did:-

1. Used LAYISO to isolate individual layers, then FLATTEN them.
2. Opened a new file, copy-pasted the flatten objects and deleted the same on the original file.
3. Repeated 1&2 for all the layers.

Center mark is where is supposed to be. Again not sure if this is exactly what you wanted. Your drawing objects seemed to be on a different plane altogether.

thanks for the reply. 

actually when i did flatten on master drawing, relative location of lines were changing... will try your method on full drawing and will let you know. 

snapping also works fine in your solution. here is the snapshot i took earlier, where center snaps somewhere else.

again thanks for reply

Problem still persist, 

if you check in side view, those polyline have different Z axis

Different orientation

those lines are not flattening... 

now redrafting all the lines over it

@Anonymous,

I noticed the same case as well (you can see the image in my first post). Please do let me know how the drawing was created (was it imported from another cad software or how was it done)? That would give an additional info on how best to approach this.
