Refrence data not showing

Is it possible that the data is in a different model of the new drawing?

I didn't get you

I see in your ref dialog that you have the Hilite Mode set to Boundaries, yet I do not see any boundary showing. This indicates that you are zoomed in to far to see the extents of the reference file boundary. Try to Fit View. I also see the reference file is scaled XXX:1500. Is that the correct scale factor. Maybe it should be 1:1?

Also, have you checked if the reference file is clipped? If so, delete the clip and then Fit View.

Yeah already I tried all the details that you mentioned above but nothing is help to get the reference data. But I detached used ref and reattached the file that time the data is visible. But Ref is too big So, the work also too much if I reattach, I find the exact place and clip the correct shape and find the levels used etc.,.. that's why I need a suggestions and solutions

Yes, we get that. However, we need to ask many questions and make many suggestions because we do not have your files, we do not know your workflow & we do not know what you have done up to this point.

Perhaps you can post your files so we can try to replicate your issue.

Yeah you're right.

I will guess when you browsed to a different file, Microstation did something undesirable to your attachment, happens. Maybe delete the clip boundary (if any), set the scale to 1:1 (unless you know the scale to something different), then fit all.

I never use  boundary option to find the ref,   I always use the hilte option instead makes it  much easier to see, I only use the boundary  option to change clips once its already clipped and in the right  place...
