Hi Burr,

Yes - but the normal thing is for those left over lines to be all your original curves that were used during your modeling.

Things like booleans and fillets should not be creating additional left over lines - if they do then that would definitely be a bug. If you have an example of something like that, please let me know and if you have an example it might help me to track that down.

But it is pretty normal to have many left over curves from previous operations, like extruding, revolving, something that you drew as a boolean cutting object, etc...

Those curves can pretty easily get in your way and prevent you from selecting the "edge" of an solid instead of that original different curve object, so it is a good idea to hide or delete those things when you are finished with them.
