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 have a fan blade, which should be ok. The Filled surface tool worked. Can you please advise me how to get the blade attached to the inner cylinder of a fan?
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!
Thank you very much! Now I understand how to use the Lofted Boss/Base tool. Unfortunately I still can not make it because when using loft there is an error: Cannot knit sheets together. I looked on the internet and saw I can use surface loft. It works but don't know how it helps me - I need a blade ..
