Can extrude on a curved surface?

[jenettezone]

Hello, I'm trying to make an extrusion on a curved surface, the surface of which is created from a swept path (img: [url]http://img.photobucket.com/albums/v461/aznf0b4eva/candlestic kscrnsht.jpg[/url])


On my attached image is a candlestick and I want to make an extrusion from the handle (selected and colored green on scrnshot). I've tried to select the surface of the handle so i could try to use it as a curved plane, and from that planemake a sketch and extrude my sketch. Of course solidworks won't let me do that, i think because you can't have a curved plane?


It looks like the person who made the following model -> http://img.photobucket.com/albums/v461/aznf0b4eva/catia.jpg<- made a lot of extrusions on a curved surface (but on catia). I want to be able to copy this (one day, hehe) on solidworks, but how do you do that? Can anyone help me please?


Is this possible with 3d sketch? I'm totally new to 3d sketch, how does it work?


Thank you so much!

oh, and I apologize for the topic typo (Can extrude on a curved surface?), I don't know how to edit it...

No 3d planes so try to offset a plane from your front or side planes to be in the middle of your handle and draw your profiel there?

More complex would be to draw the shape of your base extrusion above your curved surface on a flat plane and use the Split line feature to project your sketch onto the curved surface from the top and then use that 3d profile as your profile for another sweep.

Of course you can extrude from a curve. You start with a 3dsketch, extrude with surface, define a extrusion direction. If you want it to be solid, close up the ends then join the two solids together.
