Disable UCS if True North is not needed to prevent object tilting

[Anonymous]

I typically don't work from civil plans but in this case, I need to spot out equipment and bldg to bldg infrastructure but with is being a plan provided by the civil contractor its automatically adjusting everything to the direction of the true north orientation of the plan.  I tried some of the UCS options but I guess I am not understanding what I need to change.  I was advised that in Autocad 2019 there was simply an option to zero out the UCS the remove the coordinates adjustment but that doesn't seem to be the case in LT.  So basically I just want everything to stop tilting to match the tilt of the true north arrow on the sheet.  Its doing this for any block I insert of something as simple as drawing a rectangle.  Thank you for any suggestions.

"zero out the UCS" in AutoCAD would be the same command in AutoCADLT: did they actually give you a command name/sequence to try, or do they really not know either?

Are they using AutoCAD Civil 3D, or just plain AutoCAD?

UCS and PLAN commands set to WORLD would be a way to neutralize a file for the most part.

I tried using the world command, and its certainly possible I did it incorrectly, but all it did was change the North arrow and the x/y axis to physically pointing straight up visually on screen and tilted entire plan to the original angle of the north arrow.  Let me ask it another way in case I said it wrong.  I want the siteplan to stay as it sits on screen horizontally left to right and remove any fixed orientation that effect anything new that I add.

Let me also clarify that my experience is minimal as I am generally only adding spots, dots and lines to another persons drawing so bare with me if I am not explaining my issue the right way.

Type in WORLDUCS and press enter. What does it return? If "1", then you are in WCS which generally means north is up on your screen and you are looking at the plan view of earth, with no rotation in any axis (ultimately this is up to the drawing author).

If WORLDUCS returns 0, then type in UCS, and press <enter>, then type in "W" and press enter. Next, type in PLAN and press <enter> twice. Confirm that WORLDUCS = 1 now.

It reported WORLDUCS=1 (read only).

I went ahead and proceeded with steps you provided so I would have a better understanding of the effects and it adjusted the on plan North Arrow to pointing straight up instead of tilted and the plan with it.  After I did those steps worlducs is still 1 but I just selected the entire plan and rotated to a horizontal view and was able to place a block without it automatically applying an angle of tilt to it.  I think that's a "close enough" fix for now but I sounds like I need to learn this subject better matter to better handle it in the future.  It sounds like there may have been a problem with the originally drawing based on how you described WCS because it was set to 1 but North was not up it was about at about 30 degrees right of on screen up.

Thank you for the help

Hi @Anonymous,

Welcome to the Autodesk Community, and thank you for posting your question here in the AutoCAD LT forum.

It looks like @rkmcswain helped out with a workable solution, but I wanted to follow up and offer this link to the Autodesk Knowledge Network article on the UCS. It's a good starting point for basic info on this system, and the Related Concepts links at the bottom will allow for a deeper dive into specific subjects.
