Curved Lamp Shade in solidworks?

Curved Lamp Shade in solidworks?

Curved Lamp Shade in solidworks?

(OP)
I have been trying to create the attached, curved lampshade in solidworks. Each change in direction will be its own individual piece in reality - i just can't get the layout down. Nothing seems to handle running the loft and the curve at the same time.
Thanks for looking!

RE: Curved Lamp Shade in solidworks?

Have you thought about creating a begninning and ending sketch and running a sweep through the two profiles?  (That's one way to do it.)

RE: Curved Lamp Shade in solidworks?

Yeah, I'm incorrect though - I think it's a lofted profile.

RE: Curved Lamp Shade in solidworks?

don ... Your first image shows the shade as being convex. The second image shows a concave segment. Which shape are you actually trying to create?

RE: Curved Lamp Shade in solidworks?

(OP)
Thank you for your responses! It's just the angle from the sweep image that makes it look concave - it is a dome.
I was able to get it to work as a whole using the loft command by creating the I/D and O/D hexadecagon for the top and bottom with 4 spline curves as supports.
 My problem was every time i tried to create an individual leaf, there ended up being a diamond shaped hole in between the adjacent plane, or piece.
Still working out the kinks. Thanks Again!!!

RE: Curved Lamp Shade in solidworks?

Give the sheet metal method a try. It is very simple and as I mentioned before, allows the segment to be flattened for cutting.

RE: Curved Lamp Shade in solidworks?

Here's one attempt I made.

The key trick is using a Derived sketch to add the identical guide curve profile to a plane located at a 360/12° offset.

I then used a boundary surface and a cheap body copy to make the whole shape. You might want to do a better job and do a full set of 12 guide curves and do a proper loft/shell.

Up to you.

Good luck!

CorBlimeyLimey - I tried the sheet metal method, and it worked perfectly. It must have been that I was defining the curve with an arch at the outer edge of the shape when i ran the loft. Very slick approach, though. Thanks a ton. Now i have a flat DWG!

kgwhipp - i am interested in your approach, but i don't have SW11 (of all the things solidworks can do).

/*doesn't it seem contradictory that one can straight up profit from such a socialist activity???*/

i remain supremely appreciative to everyone!
