How to make a fan blade in SolidWorks from 3D sketch?

By luka on 29 Oct 18:31 4 answers 3 comments

I made a 3D sketch of a fan blade. The coordinates are strange, far from the origin.
I don't know how can I extrude it or better make another 3D sketch and use Lofted Boss/Base. Then I hope I will be able to make a fan ..
Thank you in advance.

    luca - go into Surfaces and use the Filled Surface command to create a surface from your 3D sketch. Then use the Thicken command to give your fan blade surface a desire thickness.

    I can't seem to open the file you attached in my solidworks 2012, the way I would go about making something like a fan blade would be to sketch cross sections on several new planes every inch or two apart (depending on the overall size), then using the Lofted Boss/Base tool to connect them. Attached is a tutorial that involves the lofted base tool (pages 14-27 specifically). You can go back and edit the sketches after to try and tweak it if you are just eyeballing dimensions, but this is the best way to make something amorphous like a fan blade.

    Hope that helped!

    The fan is finished. I just have to adjust the shape of the blades which I will do on Monday. Thank you for your help.

    luka - there was no part files included with your assembly. If you go to File, then to Pack and Go you can have SolidWorks save all of the parts that are in your assembly and then compress them into one Zip file.
