Trim to a Spline

i got a spline with lines passing through it, i need to trim these lines using the spline as the cutting edge, when I do this I have to zoom right into the intersection and trim the segment closest to the spline because for some reason it doesn't recognise the spline as 1 entity, if I selecet the line in the middle it only takes away a tiny segment of it. If you actually understood that could you please tell me if there is a lisp or command I can use that trims to splines? I'm using AutoCAD 2005.



Thanks in advance

Here it works fine to trim to a spline (ACAD 2005, SP1). Can you send me an example file?

is ur spline relatively straight? cos i find the more curves it has the more segmented the lines cutting through it will be during triming.

If it works for you and not for me then there must be a system variable for it. anyone have any ideas?

Thanks in advance

Are you really dealing with a SPLINE object, or rather a splined POLYLINE? If the latter, I suspect that you have EDGEMODE set to 1. Try setting it to

0 (off) and I think your problem will go away. ___

No. In fact, they are quite different, both mathematically and in terms of the way AutoCAD processes them. The EDGEMODE variable, for example, has no effect when trimming to a true SPLINE object. ___
