There is a new hotfix in response to Customer Error Reporting (CER) reports we have received from customers. This solution applies to all AutoCAD 2010 based products such as AutoCAD 2010,AutoCAD LT 2010, AutoCAD Architecture 2010, AutoCAD Mechanical 2010, DWG TrueView 2010, and more listed in the ReadMe.
MEASUREGEOM is a command that was released to AutoCAD 2009 Subscription customers last fall in the AutoCAD 2009 Subscription Bonus Pack 1 and was also included in the AutoCAD 2010 based products. It added new measurement capabilities such as measuring the distance, radius, angle, area, and volume of selected objects or a sequence of points.
If you entered your email into the CER dialog and hit this issue you should receive an email from Autodesk alerting you to a fix in the near future.
If you crash an Autodesk product (hopefully not), please make sure to send in the CER report with details and your email with each and every incident so we can research the problem.
Cheers,
Shaan
