ucs world is wrong

[ali kashan]

guys normally in every drawing ucs world is straight. but i have some dwgs fromt the consultant that when i try to change ucs to world coordinates it become angular instead of default result for
ucs=world
and if i try plan=world command my plan rotates to some angle
what is the settings changed in this dwg any one can tell me
thnx

Go to menu View - 3D views - Current UCS or World UCS

[James Taylor]

how do you mean angular?? do you mean its doesn't line through with the horizontal and vertical lines of the drawing? will it not just be the case that the drawing has been done with north pointing directly vertical??

[ali kashan]

Ok let me explain
ist image is the image with command line ucs/world
second image is with command line plan/world
may b it clarify my qusetion

I think if you determine the angle to that world UCS and start a new drawing and insert it as a block it will correct it for you although you may have to rotate it when in the new drawing.

[James Hindley]

if a drawing demands that you set your ortho lines to follow a certain angle and you dont want to rotate the drawing then you can use the command.

snapang then simply click the basepoint of an angled line and click somewhere along its lenght -

this will set your UCS to the angle of the desired line.

This way you can set your ortho off that lines angle not the standard straight up and down setting....
