# Measuring distance in rotated UCS

281 Views, 3 Replies

I have a plot plan, that is rotate about 31 degrees off true north. So when I draw inside the plan, I rotate the UCS to be able to follow a "plant" north.

> UCS > point 1 > point 2 (along x axis) > point 3 (along y axis)

> PLAN > enter > enter

Now, I'm trying to measure a distance between 2 points with my drawing rotated along a new UCS. However, it keeps giving me the measurements as if it were still in the WORLD UCS.....so my x and y values are weird numbers instead of the nicely rounded numbers to which I have offset from a certain point.

> DIST > point 1 > point 2

How do I get my distance to show me what the x and y distances are in the UCS that I have rotated to, instead of showing me the x and y distances based on the WORLD UCS? I know I'm missing something, but just can't remember what.

Thanks for any help.

DIST should give you the correct answer. It returns two lines of numbers. On the first line it will give you the correct straight line distance and the angle of your ucs, on the second line it will give you the difference of the start and finish points on the x,y, and z axis, which may not mean a right lot. Do you by chance have your command line reduced down just to show the last line of command history.

Make sure enough of your command lines are visiblr you can see all the information the DIST command returns

Steven -

Yes, I agree. DIST should give me the correct information. But for some reason, it isn't. I have my F2 open (Command dialog box) on another screen, so I see everyting that I need to know.

Eventually I just WBLOCKed the entire drawing, opened the wblock and it was working fine.

I really don't understand why it was acting up to begin with, but thanks for your suggestions.
