XREF and ZOOM EXTENTS

Anonymous — Thu, 22 Oct 2020 18:48:00 GMT

Hello - For the life of me, I can not figure out why when I zoom extents my xref files are tiny in the drawing. I don't see any floating bits, I've cleaned the drawings multiple times. I need assistance with another pair of eyes. Anyone out there can help? I've uploaded a etransmit. Thanks so much!

I think when you insert xrefs as "attachments" instead of "overlays", zoom extent will include the attachment point (in this case, includes 0,0). Try using "overlays", we typically use "overlay" as standard to avoid circular xref issues. There are few cases where I intentionally use "attach".

It looks like one of your xrefs has a grip at 0,0. I moved everything closer to 0,0 and everything was good. Sadly I only had a few minutes to look at this today so I'm not sure if there are other issues. Good luck to you!

One shouldn't need all drafting to be near 0,0 for zoom extents to work. Most of my CAD drafting is georeferenced to some state plane coordinate system.

I tried with "overlay" and the same issue is occurring.
I believe it has something to do with the survey needing to be scaled by 12
so it is in architectural units.

Unfortunately, if you move it like that then you lose the relationship the
drawing has to the coordinates of the survey file.

Agree. I work off the survey. I reference the survey into a new drawing and
then scale it by 12 to be in the architectural units. Then start my work.
The architectural file comes in at 0,0 and I move that to be relative to
the survey. Simple. Then when I zoom extents it should all zoom relative to
the drawings unless there are floating bits. It's bizarre.

That's strange. I changed to overlays and it did seem to work.

That's really strange. Let me try again.

That's not what I said; ZE is working as expected. Did you open the drawing to investigate?

Nope. Didn't work on this end.

Yes, I see the grip that is away from the drawing. I did notice this however, you move that it's relative so the grip moves too. I've opened the survey drawing too, unsure where it's coming from because it zooms fine in the original drawing.

Hi @Anonymous the problem seems to be with the 20-04 l-ar-01.dwg. If I open that drawing and detach the base plan xrefs and attach them again and save the problem seems to go away.

Yes, I realized that too but I'm unsure what is causing the issue. Any
thoughts?

Re: XREF and ZOOM EXTENTS

user181 — Thu, 22 Oct 2020 20:48:17 GMT

I don't really have an idea of what would have caused it since it's not normal behavior.

Me either, the file is clean.

What is unusual is if you open the L-AR-01 file and the associated Base Plan xrefs and zoom extents they are correct. Something happens when the AR file is Xrefed into the SP-01-PA file. I've recreated them over and over again and still can't figure it out.

Acad doesn't like your invert-xclipped xref(A-BASE_PLAN-01) in file '20-04 l-ar-01.dwg",

when your block 'Door (2D)-38' include a wipeout (A-base_plan-01.dwg).

Switch xclip clip-side or remove the wipeout from this door block

and it works as expected. I am going not deeper, i am out 😉

Oh thank you, thank you, thank you! That was it. I exploded everything in
the A-BASE files since they are just for reference and whala - it's normal
now.

Thank you for going deep into this! Greatly appreciate help!

And everyone who attempted to take a look.
