HI

IM USING REVIT 2015 AND AUTOCAD 2015.

IVE BEEN LINKING THE CAD FILES AND USING THEM FOR REFERENCING AND MODELING IN REVIT. I HAVE NEVER HAD ANY ISSUES BEFORE BUT YESTERDAY MORNING MY REVIT STARTED FREEZING AND GIVING ME THE TIMER SYMBOL AT EVERY COMMAND. THE REVIT PROGRAM HAS ALSO STARTED 'NOT RESPONDING.

BUT... THIS ONLY HAPPENS WHEN MY LEVEL -2 CAD FILE IS LINKED. THE PROBLEM DOESNT OCCUR WHEN THE CAD FILE HAS BEEN UNLOADED OR REMOVED OR WHEN ANOTHER CAD FILE IS LINKED TO THE SAME LEVEL -2 FLOOR PLAN.

I HAVE BEEN WORKING ON MY REVIT MODEL WITH THE SAME CAD FILE LINKED FOR MONTHS AND HAD NO PROBLEMS.

HAS ANYONE EXPERIENCED THIS?

When you link are you checking the 'THIS VIEW ONLY' box?  If you don't check that box, then Revit inserts the CAD as a 3D element and has to show it in every view.  That is a real problem if you have several views open.

I REMOVED AND AND RELOADED IT AS 'CURRENT VIEW ONLY' BUT SAME PROBLEM PERSISTS.

IS THERE ANYTHING ELSE I CAN TRY?

Audit the file just incase...

CAD file size? 

Is the origin a long way away?

What happens if you link this in a new project?

I HAVE...

MOVED THE CAD FILE CLOSER TO THE ORIGIN

STRIPPED THE CAD FILE, CHANGED THE CAD TEMPLATE

THE CAD FILE SIZE IS NO BIGGER THAN THE OTHER WORKING CAD LINKED FILES

I LINKED IT INTO A DIFFERENT REVIT PROJECT ... SAME PROBLEM

I THINK ITS A CAD PROBLEM RATHER THAN A REVIT PROBLEM! BUT THANKS FOR THE SUGGESTIONS!

SOLUTION....

THE REASON THIS HAPPENED WAS DUE TO SPLINES IN A CAD BLOCK IN THE LINKED CAD FILE

WE INTRODUCED A NEW CAD BLCOK INTO CAD FILE RECENTLY. THE PLINES UPSET THE CAD FILE IN REVIT (NOT SURE WHY) BUT ONCE WE CHANGED THEM TO POLYLINES OR REMOVED THE SPLINES, THE PROBLEM WAS RESOLVED AND THE FREEZING STOPPED.

HOPE THIS HELPS OTHERS IN FUTURE
