Other usage issues

i want to edit arbitrary vertex of a arbitrary shape just like what has been discussed
here: http://www.opencascade.org/org/forum/thread_14071/
here: http://www.opencascade.org/org/forum/thread_15411/
and here:http://www.opencascade.org/org/forum/thread_14514/

and i can edit vertex on an edge now, use the method in http://www.opencascade.org/org/forum/thread_14071/
thanks for Pawel and all other people contributing for this problem.

but there is a problem, when i move a vertex to another location, previous face(i mean plane here) with this point usually will not be a plane now. thats a problem for both "reshape" or duplicate mechanism. anyone has any idea about this?

thanks for any help.

Hi li,

you could convert your plane into a nurbs curve and then modify the control point.

thanks very much Pawel:

its a good idea, i will try it.

however it seems the modified face will be a curved surface, isn't it? if so , what should i do if i want to keep all faces as planes? split the face ? how ? i even don't know which edges form the new faces.
