    Default Trim, trim objects/selection issue 2010

    Hi there.

    I am using civil 3d as 2010 for some general editing of larger dwgs for use down in 14.

    I use to use 2008 and this is the first time using 2010 for this purpose in a few months.

    Although I have C3D I thought this was a more generic cad question (Hope I posted in the right spot)

    The issue...
    When I want to trim a mass of random polyline (contours) to a rectangle...I select the rectangle as the abject to trim to...then I use a crossing to select a mass of computer is taking a very, very, very long time to actually trim the objects.

    When I select the polylines one by one it is very snappy/quick.

    I have tried this with the extend and projection options in different modes and this makes no speed difference.

    With 2008 there was never a problem...very fast, very efficient in the task.

    Any ideas ???

    Thanks in advance

    Have you tried Fence selection?
    Do the polylines contain lots of short segments near the point that they cross the rectangle?
