You will need to get the entity and then use the explode funtion to
expolde the pline to an array of entities. This will not disturb the
orginal entity. then cycle through the exploded enties and go through
some logic of finding which entitiy you have selected.
here is a code snipit that I did. I was looking for only the curves.
this is in LDD so it may be alittle foreign to some. it is not complete
code so don't try and run it on its own.
Dim explodeOBJ As Variant, pLine As AcadLWPolyline
pUtil.GetSubEntity Object, PickedPoint, TransMatrix, ContextData, vbCrLf
& "Pick CURB return at the intersection: "
If TypeName(Object) = "IAcadLWPolyline" Then
Set pLine = Object
Err.clear: On Error Resume Next
explodeOBJ = pLine.Explode
alg.StationOffset PickedPoint(0), PickedPoint(1), pstation,
offset, pdirection
On Error GoTo 0
For i = 0 To UBound(explodeOBJ, 1)
If TypeName(explodeOBJ(i)) = "IAcadArc" Then
Set getcurve = explodeOBJ(i)
Err.clear: On Error Resume Next
alg.StationOffset getcurve.startPoint(0),
getcurve.startPoint(1), Station, offset, direction
alg.StationOffset getcurve.endPoint(0),
getcurve.endPoint(1), station2, Offset2, Direction2
If (pstation < Station And pstation > station2 Or
pstation < station2 And pstation > Station) _
And (poffset < offset And poffset > Offset2 Or poffset
< Offset2 And poffset > offset) And Abs(offset - Offset2) < 75 Then
found = True: Exit For
End If
End If
Next i
