How to remove/ join faces on a single part?

michael_stallsmichael_stalls Member Posts: 46 PRO
Hi im not sure if this has been addressed before (if so please delete or move thread). Below is a plan form view of a wing i have created by by lofting  between two airfoils of the same chord (length) and then lofting with guide lines to create the curved tip. Is there any way to to remove the vertical line between the constant chord part of the wing and the tip as it doesn't in fact represent any real feature? thanks
Michael

    Thanks Konstantin i have voted for it too!

    Just for a little bit on insight on this, internally to our system there must be an edge at the border of any two surfaces that do not have the same mathematical surface definition.  Other CAD systems choose not to represent these "smooth" edges to the user, but for now we have chosen to display them (and maintain the separation of those two faces as smooth but distinct faces).

    As always, thanks for the IR and the vote!  Even though this is how it is now, doesn't mean we couldn't treat it differently in the future if we hear the same opinion from many users.  Hopefully this clears things up a bit, at least for your mental model of why it is there.

    I should notice those IR is not for hiding smooth edges representation. It is for creating spline surface, which incorporates common math definition for a number of faces (with some tolerance of cource)

    Thanks for the extra info @konstantin_shiriazdanov

    Thanks for the reply. I understand this and it IS useful to have these points/edges  too. Maybe what I'm really after is a way to select and hide certain edges. (Either in the model or drawing) There is a global option to hide edges. I dont know if this is difficult or not. Maybe i should put in a improvement request 
    Thanks Michael

    I would appreciate having an option to display or hide these edges. Thanks.

    What type of surfaces are these? If not NURBS then what?

    Also, how do I formally link open surfaces into a single part? I can only do it now by creating a closed body then deleting the construction I used to artificially close it.
