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 contours....my 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
