is there any way to convert an edge of a part in an assembly to the surface of a rolled sheet metal part and have it stay on the surface when flattened?
How? Sketch and 3dsketch wont do the work...
ok, how then?
The compressor blade profile needs to be 2D for your planned work flow. Then use path/profile to make the part. Then trim it. if the design is more 3D than that (multiple profiles), you will need to make a block and start trimming it or input a bunch of 2D profiles and trimming. True compressor blades can be very complex. Not an easy task in works. I would look at possibly changing workflow to making a set of surfaces that enclose a volume. It all depends on what you need for manufacturing.
You state "convert an edge", but convert entities projects to the sketch's plane losing the length of the curved mating part.
Try an intersection curve and use this to create a base flange.
This edge will be curved, so you may need to create an extrude and covert it to sheet metal using a different edge.
i just ended up grabbing the profile of the fin and using it to make a cut thru the rolled id and od sheet metal parts then arraying it. when flattened i exported to dxf and changed the cuts to the correct layer for our plasma to etch instead of cut. i've done intersecting curves before, just not for what i was trying to accomplish. i was ultimately wanting to give the guy something to align too when welding the parts together so he didnt have to lay it out himself. i always try to make a project easier for the person building it. thank you all for your help
