Duplicate Line selection and deletion macro

[TheKyle9]

I am bringing in a 2D profile from an IGS file, the profile has 3700 elements (lines and curves) then it has a totally new set of lines and curves that form the same profile on top of it. Essentially, its a single geoset with duplicate lines on lines. Is there a tool in Catia (or custom macro) to isolate only one group of elements that form the profile without going thru each line and deleting one of them?

I think the operation I'm looking for is similar to "OVERKILL" in AutoCAD...

thanks

if it's all 2D:

make a big join (no check connexity - no check manifold)

create a plane offset at 1mm

project the join on the offset plane

isolate the projection 1 (copy paste as result)

delete all but the isolated projection 1

project the isolated projection 1 back on the original plane

isolate the projection 2

delete isolated projection 1

disassemble isolated projection 2

delete isolated projection 2

Good suggestion to project, I discovered (after you create a smart join) you can project dumb up to the offset plane- however, you must project along a direction and turn nearest solution off. That will (apparently) get rid of duplicate lines, I'm not really sure WHY... but it worked so I'm happy.

Thanks for your help!
