Hi @mikegera
Try this:
If the objects are at different elevations, your dimension won’t be accurate.
Chicagolooper
Hey @ChicagoLooper ,
The circle and the line are both on the same plane. But, I did notice that some entities in the assembly I'm working with are not, and that could be affecting things.
What is the best way to push everything in the drawing to Z=0?
Thanks.
Use FLATTEN command.
Express Tools tab in the Ribbon=>Modify panel=>click the drop down arrow=>click Flatten Objects
Chicagolooper
Perfect.
Thanks!
Were the assemblies drawn by others? AutoCAD is a 3D program and those elevation values may be important.
Better solution if you don't want you additions to use elevations would be to set the OSNAPZ (System Variable) to 1 and make sure the ELEVATION (System Variable) is set to 0. Any objects or dimensions you add using osnaps will be with an ELEVATION of 0 without converting the entire drawing to 2D which might make it useless to others.
Hi Tom,
Thanks for the very helpful rely. Often drawings are a mix of blocks from many sources. Sometimes, I don't realize that there's 3D content.
Is there a way to globally "turn off 3D"? i.e. outright "disable Z"?
Thanks.
Hi @mikegera
Cannot 'disable' 3D elevations.
Use FLATTEN command to move the objects from their current elevation to Z=0 so they're all on the same Plane.

For some reason, the FLATTEN command does not always work. For example, I found a text entity that had a nonzero "Position Z" (21.3655). FLATTEN did not change its Position Z to zero, it remained at 21.3655.
I also found that FLATTEN cannot penetrate blocks. Is there a setting to allow it to do so?
Thanks.
Hi @mikegera
Do you know whether this drawing began in Revit?
Yes, it did or no it didn't? I don't know and I don't care?
Is it possible to upload more screenshots?
Select a text entity nonzero "Position Z" then upload a screenshot with the text is still selected. Include the Properties Palette in the shot so the text can be evaluated.
Next, select a block which cannot be penetrated and upload a screenshot with the block is still selected. Include the Properties Palette in the shot so the block can be evaluated.
BTW, do you run Revit? Is this an architectural drawing?
Chicagolooper
Chicago,
1. Sorry for the delayed response.
2. I do not use Revit. While I am not the originator of the drawing in question, I'm nearly certain that Revit was not used at any point.
3. This is not an architectural drawing. It's an electrical schematic.
4. I did make an interesting discovery: the issue is NOT present in AutoCAD mechanical. It IS present in AutoCAD electrical.
I am not ignoring your other questions, but thought I'd share this first.
Thanks.

I have both variants, 2023 versions, as do many others around here I suspect: can you share a DWG that exhibits this?
If you can figure out the FLATTEN issue to get it to always work, you could set AutoCAD to run a LISP each time a drawing is opened (in your acaddoc.lsp file) that flattens it first. It would do it for every drawing you open, even one that's already been flattened, but it would keep you from accidentally working in a 3D drawing.
