Problem Triming Contour lines...Any suggestion?

Hi  all,

 

Up to now, I was able to trim contour (elevation) lines simply by drawing a polyline across the contour lines and use the trim command. But the function suddenly stop to work on my computer.

 

I have tried the function on other computers and it works very well.

 

Now, on my computer,  I can only trim one contour line after the other by adjusting the polyline to the same elevation as the contour line. This is rediculous if I have to trim hundreds of contour lines.

 

Because the problem is only on my computer, I suppose i have mistakenly apply a command that have change the settings on my computer.

 

I have reviewed my settings but cannot identify the problem.

 

Any suggestions?

Sounds like you need to change the 'Project' option to UCS. Check the command line after you execute the Trim command. You enter P for Project.

I'd agree with this generally but it doesn't sound like the OP is working with a surface - just trimming polyline contours

I think we need to know exactly what program and version you are using.  When you select these contour lines are they polylines?  If so, where did they originate?

Thanks for your suggestions. I have resolved the problem by resetting my AutoCAD, following steps provided by the AutoCAD Civil 3D Services & Support!
