splitting error

[Anonymous]

i'm creating a site plan and i'm trying to split a surface but i keep getting the following: "The splitting boundary must split the Surface into exactly two pieces" What does this mean? i've done exactly what i've done in the past w/o any problems

Typically the message:

“The splitting boundary must divide the Surface into separate pieces. There may be a gap in the splitting Lines or the Sketch may be incomplete.”

can occur because of:

1.  The split sketch lines do not form a closed loop

2.  The split line does not intersect the toposurface specific geometry you are trying to split

Could any of these points apply to your site?

Thank you,

yes the 1st option.  i actually figured it out.  the tinest little gap was in my sketch lines.  thanks.
