Can't see everything in viewport

[jgratton]

The only way I was able to see all the MS geometry in a viewport was to wblock it and insert it into a newly created drawing.

I am very curious to know why and hope someone here has experience with this. Is it something to do with limits or z elevation? I looked at the system variables but nothing suspicious there.

We inherit these drawings from others and no doubt this will come up again.

I would guess that the issue is related to the "Z" depth in the viewports. I scaled a "Z" value difference of up to 42,393,852' - 8" between the groups of data.

When I adjusted the "Z" values everything was visible in all viewports.

I do not see any clipping going on in the views. I've never seen numbers this far apart so this is pure speculation but, I'm guessing that the views just can't calculate the data that far away?

Thanks - Did you use the Express flatten to do that?

Since I was just testing the file I just used "move" to shift the groups of items one group at a time.

I did notice that the line work in MS were on different planes from WCS (plan view), they were drawn in a 3d plane along the WCS x axis and placed in different coordinates.
Is there a reason for this? This would explain the z value differences between them.

(see attached dwg, model space)

I also noticed the right viewport had layers frozen "per viewport", but thawing them didn't seem to matter.

Wow, thats an interesting problem. I did Everything I could think of.

This started as a 3d model and I'm not sure what they used to make it 2d but obviously it wasn't good enough.

Thanks for your time.

Your welcome.
It's seems as if when it was a 3d model, they used the "flatten" command while in different 3D "Right" views (not plan "top" view) but perpendicular to "top" (WCS plan view).

Good Luck.

I think the best way to solve this is to have the company resend a fixed version. they aren't paying you for this. put the fix it stuff on thier bill.

My guess is that they just selected the objects individually rather than globally and moved them to 0 manually instead of using flatten. This would of course cause its own problems which appears to be part of why things look the way they do.
