Firts check, make sure that all entities are visible in the screen, click in icon RESET ALL VISIBILITY OPTIONS, this will cause that all FEMAP entities to be plotted in the screen.
Next you can issue command GEOMETRY > SOLID > CLEANUP > SELECT ALL and making sure to activate option ENABLE ADVANCED CLEANUP, this way all solids will be cleaned
Now you are in position to investigate to delete localy any geometry. For instance, you can try DELETE > GEOMETRY > CURVES > SELECT ALL command and you will get rid of all isolated curves. Repeat for POINTS.
Next you can use MESHING TOOLBOX and play with command FEATURE REMOVAL > CURVES > COMBINE SURFACES, enjoy!!.
try my API. If those Curves belong to a Solid, you can delete them and its Points with the following API:
Sub Main 'Delete Curve(s) from Solid by Peter Kaderasz Dim App As femap.model Set App = feFemap() Dim curveSort As femap.SortSet Set curveSort = App.feSort Dim curveSet As femap.Set Set curveSet = App.feSet Dim notSolidCurveSet As femap.Set Set notSolidCurveSet = App.feSet Dim curveID As Long Dim solidID As Long Dim feCurve As femap.Curve Set feCurve = App.feCurve Dim Msg As String Dim curves As Long Dim curves_NonDeleted As Long App.feAppMessage( FCM_COMMAND, "Delete Curve(s) from Solid(s)") rc = curveSort.Select( FT_CURVE, True, "Select Curve(s) to Delete from Solid(s)") If rc = FE_CANCEL Or curveSort.Count=0 Then App.feAppMessage( FCM_ERROR, "Solid Curves not selected - Cancelled") App.feViewRegenerate( 0 ) Exit Sub End If curveID=curveSort.First While curveID>0 rc=feCurve.Get(curveID) If feCurve.Solid(solidID)=FE_FAIL Then rc=notSolidCurveSet.Add(curveID) Else rc=curveSet.Add(curveID) End If curveID=curveSort.Next Wend If notSolidCurveSet.Count>0 Then rc=curveSort.RemoveSet(notSolidCurveSet.ID) App.feAppMessage(FCM_NORMAL, notSolidCurveSet.Count() & " Curve(s) Skipped...") End If If curveSort.Count=0 Then App.feAppMessage( FCM_ERROR, "Solid Curves not selected - Cancelled") App.feViewRegenerate( 0 ) Exit Sub End If curves_NonDeleted=0 rc=App.feViewShow(FT_CURVE, curveSet.ID) If App.feAppMessageBox( 2, "OK to Delete selected Curve(s) from Solid(s)?") = FE_OK Then If curveSort.Count > 0 Then curveID=curveSort.First While curveID>0 curves=App.Info_Count(FT_CURVE) rc=App.feDelete(FT_CURVE,-curveID) If rc=FE_INVALID Or curves-App.Info_Count(FT_CURVE)=0Then curves_NonDeleted=curves_NonDeleted+1 End If curveID=curveSort.Next Wend Msg = curveSort.Count-curves_NonDeleted & " Curve(s) deleted from Solid(s).

You didn't find the "Enable Advanced Cleanup", because you use an old version of Femap. But in this case you can use the Solid Cleanup command too (switch on all checkbox).
you deleted 139 curves, but 80 curves are nondeletable. Thera are maybe edges of a solid.
You can see the surfaces of this solid with Window / Show Entities... command, Entity type is "Surface" and in Selection box using method "using Curve". Similarly you can see solid if you choose Entity type "Solid".
Can you attach geometry?
All the stuff you see away from the surfaces of the ship hull are Parasolid Wire Bodies. Parasolid has solid bodies, which are a closed set of sheets, sheet bodies, which have free edges, wire bodies, which are curves, and vertex bodies which are points. The IGES importer brings in curves as wire bodies. After import, use Delete Geometry Solid (which is really Delete Parsolid Body, solid, sheet, wire, or vertex). Pick the curves away from the ship, and you can delete the curves, and their points at the same time.
There's still some wire bodies up with the hull surfaces as well, I don't know if you need to keep these or not. In the Model Info Tree, you can see the wire bodies, they've got a Solid Cylinder and with a curve to show that they're Parasolid wire bodies, you can select them all in the Model Info Tree and right-click to delete them.
