The behavior in AutoCAD 2012 has changed with regard to the UCS command. I am trying to rotate my UCS along the Z-axis.
In 2011, I could enter UCS [enter] Z [enter] then select 2 points on *any* line using ENDpoint osnaps to have the ucs rotate along the Z-axis at the angle of the selected line.
Now in 2012 when I enter UCS [enter] Z [enter], a rubber-band line displays anchored from a pre-selected point which appears to be the drawing origin, usually 0,0,0. I am only allowed to select a single point, which results in the UCS NOT rotatating to match the line as before.
I am aware that I could now use the OBject option, and then select one end of the line. This is fine except it does not work if I select a line that is part of an attached xref. With the old method in 2011, I could select 2 points of *any* line.
I am also aware that I could "type" in a value in both cases above but that option is too time-consuming and error-prone.
Are there any legacy options available for the UCS command to make it work as before? Or is there a way to override the UCS-Z command option to not pre-select the first point at the drawing origin?
I also preferred the way UCS > Z worked in AutoCAD2011 vs the way it works in 2012-2013. The change is no doubt due to the 2012 UCS icon being directly editable with grips. I don't know if you can get the old behavior back, but here's a video showing several methods to get the same result.
After typing UCS, snap to the endpoint of your line, snap to the other endpoint. Don't type Z in other words.
Use UCS, 3, pick the endpoints and an arbitrary Y point.
Grab the UCS and move it to the endpoint, grab the X axis grip and snap to the endpoint.
The problem with this is if your points picked are not on the same plane in the x or y, your UCS will also rotate in on these axis and not just on the Z. With the old command and selecting Z when rotating you did not have to worry about this.
