AutoCAD MEP 2010 Product Update 1 Now Available

General Updates to AutoCAD MEP

The following defects have been fixed in AutoCAD MEP 2010 Update 1:
  • Duct Flanges are displayed incorrectly after moving a duct using grips.
  • Velocity in Duct Modify does not match the Velocity in the Properties Palette.
  • Add Selected does not work correctly when duct height is greater than duct width.
  • Takeoff for branch is not sized correctly when duct height is greater than duct width.
  • Top and Bottom Elevation are incorrect in tooltip when duct height is greater than duct width.


  • A crash may occur when closing a drawing with an EPD file that has a relative path.
  • A crash may occur when converting multiple blocks to Devices.
  • Wire will only connect to one connector on some scaled devices.
  • Device modify via grip edit doesn't move or maintain its orientation as expected.
  • The Add Automatic Property for a Device was not retrieving the Load Category or Number of Poles.


  • The formula for percentage slope by angle is incorrect. Fixing this means that an existing tool in which a specific number for percentage is stored will produce a different slope due to the new calculation.
  • Pipe layouts with Very low slope cannot be created correctly.
  • The Parallel Pipe command places new pipes on the wrong layer when systems use different layers.
  • Some Pipe created in previous versions of AutoCAD MEP snaps to fittings when opened.

Multi-View Parts

  • Some linework is missing from certain MvParts.
  • Radiator insertion fails, using the window option, if the radiator width or length is located in a basic table.
  • Radiator Import does not set property data properly.
  • Radiator valves are not aligned to the radiator when inserted using the plus grip.


  • Haloed or hidden appearance for Plumbing Lines, Schematic lines and Wires do not display correctly.


  • CollisionDetection does not work as expected.
  • "Copy to Clipboard failed" dialog will appear when copying an object that has been copy/pasted from another drawing.
  • A fatal error will occur when creating an elbow with multiple segments.
