TheValross Posted January 27, 2017 Share Posted January 27, 2017 Hello! Im struggling with the modeling of a Computer fan. My idea is to make a fan with a diameter of 120 mm and to make it look somethin like the fan in the picture. . To create the fan blades I have used a coil and then tried to make the soft edges using a sketch and then cuting it out (fillet did not work well because I could'nt get the shape I was looking for). The thing that I ran upon was that when I used a circular patern it cut out things of the other fan blades and it al ended up in a mess.. Any suggestions on solutions?

JD Mather Posted January 27, 2017 Share Posted January 27, 2017 Any suggestions on solutions? Attach your file(s) here. If you want the blades uniform thickness, then I would use a trimmed surface coil. Then Thicken. If you want non-uniform thickness then that becomes a bit more difficult using Loft. Of course, create one blade and pattern. Not quite the same as your design - but might give you some ideas. http://www.cadtutor.net/forum/showthread.php?34738-Impeller-Headache&highlight=impeller http://www.cadtutor.net/forum/showthread.php?42799-STUCK-on-impeller-vanes&highlight=impeller Quote Link to comment Share on other sites More sharing options...
shift1313 Posted January 28, 2017 Share Posted January 28, 2017 This isn't inventor, and its really old, but here was a fan tutorial i probably did about 7 years ago in solidworks. http://shift1313.wix.com/design-splash#!__tutorial-downloads page 33 is where i make the blades and one method. I actually just did a plastic part design course for Pluralsight creating a pc fan. I did this with Fusion360 but the process is similar.

Lazer Posted February 19, 2017 Share Posted February 19, 2017 Use sketch and loft to make one blade then use revolve to make the others. Quote Link to comment Share on other sites More sharing options...
