I want to make a shop drawing of two conical part which connect togather .i wish to know how draw interfac in connect point of this connection.
Create an assembly of the two parts, and make a drawing of the assembly.
I have been try it with trim surface but the problem is when use surface it will not possible to inser bend in sheet metal.
It is hard to know exactly what you want but I have attached a sheet metal part showing what I think you want to do, if this is incorrect please upload a part file for someone to have a look at.
What I did was to create a sheet metal cone, I then did a linear pattern so as to give me two intersecting cones. I then created a 3d sketch and used the intersection curve feature to create a sketch of the intersection between the cones, I then did a cut extrude to remove the excess material.
