How can I delete a split line feature without deleting all the split lines created later? When I delete the split line, it removes all features that were created after the split line I am trying to remove.
One way of doing this is with multiple surfaces. First you do a 0mm offset to create a duplicate of the surface you are trying to split. Hide this surface for now. Next you will do your split operations on the initial surface. Once you have the geometry created with the use of the split lines use either delete face or delete body to get rid of the face/surface that has the split line. Unhide the zero offset duplicate and you now have a clean face that is matching your geometry.
If you need to keep certain split lines in the model you may have to create more than 1 0mm offset duplicate.
The round face in thescreenshot was created this way.
-0mm offset to duplicate
-split round surface to create edge for the blend
-after blend, delete face or body to remove the split surface
-show the 0mm offset duplicate face
-stitch together and have a clean transition and surface
If you have I think, 2016 or later, there is this option when deleting a feature.
Click advanced then make sure none of the children are checked.
If this doesn't work you will need to go back and remove all the parent/child relations.
If it does work you will need to remove all the blown up features and reattach them.
Take your pick
One work around is to force your original split line to fail by editing its sketch and changing all the sketch entities to construction. Exit the sketch and when it prompts you, hit rebuild anyway. Any subsequent feature that was dependent on this split line will probably fail also. Edit those to resolve any issue. Once those are all cleaned up, you can delete the original split line without it affecting anything below it.
