If you click on the link I posted about earlier, you will get this:
On August 23, 2010, Autodesk released Update 1 for AutoCAD 2011. Unfortunately, Update 1 introduced an issue when conducting certain operations that may cause AutoCAD to shut down. This issue affects a small number of users.
We have removed Update 1 and will reintroduce it in the near future when the issue has been resolved. For customers who have already installed Update 1, the hotfix that resolves this issue has been posted at the following location:
AutoCAD and AutoCAD LT Layer Manager Hotfix
Please be assured that Autodesk is wholly committed to the quality of AutoCAD, and regrets this error.
Having been pretty critical of Autodesk lately, you might expect me to dish out another serve for this. But I won’t. With the best of intentions, this stuff happens. Autodesk has done the right thing in recalling the update and providing a workaround for customers who have already applied it, and a fixed Update 1 should get released soon enough.
CAN SOMEONE PLEASE SUGGEST HOW TO STOP LINEWORK FROM DISAPPEARING FROM MY ACAD 2011 DRAWINGS(ON SCREEN) WHEN THEY HAVE BEEN DRAWN OVER AN ORTHOPHOTO?!
“REGEN” OR “DRAWORDER” DON’T SEEM TO HELP.
MY V.A.R. AND AUTODESK CAN’T SEEM TO REMEDY THE PROBLEM.
THANX………MARC
