Strange xref behaviour

[PeterHarding7326]

Hi, 

I have a master building drawing OVL1 that has a number of event spaces on it in a large exhibition centre

there are two contractors that collaborate in each space. Party, Breakout, Networking, Plenary

HTH - a technical supplier

TBP - a event designer

we have an overall master drg is made showing all the drawings together to create a composite drawing

where 

hth  - party, breakout, networking and plenary individual drawings

and

TBP -  party, breakout, networking and plenary individual drawings

and

OVL1 building drawing are all xrefed in

To be able to work on each area the 

HTH contractor would create a drawing for each area such as party

In HTH party drawing

i have a HTH contractors drawing entities and

Overlay xref of OVL1 (clipped with a rectangle window)

TBP Party as an overlay xref

In TBP party drawing

i have a TBP contractors drawing entities and

Overlay xref of OVL1 (clipped with a rectangle window)

HTH Party as an overlay xref

HTH party dwg works as expected, but when i open up but TBP party dwg when i zoom extents, it zooms to a blank space, when i click the OVL xref it shows the correct clipframe and a phantom invisble but now highlighted clip frame that is causing the zoom into open space.

how can i fix this!

tried everything i can think of

This illustrates the problem, interestingly one xref the furthest right at the top doesnt have the problemthe phantom blue squares from the highlighted refs

[PeterHarding7326]

interestingly the one that works doesnt have the TBP-OVL master build xref clipped in it

[PeterHarding7326]

As soon as you clip that master drawing then the problem is evident

Hi Peter,

Have you tried to use AUDIT command to find and fix errors in the problem drawing?

[PeterHarding7326]

Yes I have done that and none found

Can you share the whole set of drawings here?
Or you can send it to my mail: [email protected]
I'll look at it.

[PeterHarding7326]

It seems to be connected with clipping the master building overlay In HTH – PARTY drawing

In HTH – PARTY

There is

TBP-OVL2 as overlay clipped

TBP-PARTY as overlay clipped

Ie

In Overall master summit 2019

TBP-OVL2 is an attached xref unclipped

HTH – PARTY is an attached xref unclipped

If you clip the TBP-OVL2 in HTH – PARTY then it shows a phantom clip border when in the SUMMIT Master

Have sent a dropbox link to your email with all the drawings. - let me know if you dont get it

[maxim_k]

Got it, looking into it.

[maxim_k]

I sent dropbox link ti edited set of drawings to your email.
What I have done:
I changed the type of xrefs in the all drawings in the set from Overlay to Attachment.

[PeterHarding7326]

Maxim,

Thanks for looking at this, so is this a bug and switching to attached from overlay fixes it, because it would seem that overlay is the right way to go here?

or am I missing something.

Best

Pete.
