Can someone please explain x/y coordinates in note parameters in drawings? (SW 2014)

Mike, the first X/Y coordinates are the start point for the line, followed by the second set of X/Y coordinates which are the end point. Below them it represents the delta length in X and Y.

Your first vertical line shows a length of 1.964~ along the Y Axis and the second shows a horizontal line that is 1.691~ in length along the X Axis.

Ninja Edit: The third box represents the start point of the text, at least I believe it's supposed too ... Though the numbers shown do not seem to be valid. It appears as if they are 2x the value they should be, but honestly I don't know. Sorry ...

for some reason, the X and Y coordinates of the notes include factors for the sheet scale. And are to the "origin" of the note - left for left justified, right for right justified, etc. (not necessarily the center).

I am seeing the same thing.   When I edit my sheet format:

X coordinate of the line:

X coordinate of the "DRAWN" note:

When I create a point and manually type in the x coordinate of 11.4, it places it right next to the line.

When I make a copy of the "DRAWN" note and type in 11.4 for the x coordinate, it is actually sitting at the x coordinate 5.7......hrmm.

So, I opened up a blank template......and did a test by editing the sheet format of the drawing:

Then I exited the sheet format and drew on the sheet view:

When I am editing the sheet format, the note x and y coordinates are scaled by 1:2 but when I am on the sheet view, they are 1:1.

Then I did a quick search on the knowledge base:

Sounds like this is a known issue.

I am using SW 2015 SP5 by the way.
