[vavenash]

hi,


can anyone guide me on creating fan blades of a Table fan?even the outer covering also(wired).


thanx in advance


bye

Hi,


My Suggestion is Just make Dtm Curves(twisted Profile)in any middle planes & getit projected on cylindrical surface, then u can proceed with offset in tweak.


R u a Student of CADD CENTRE?


Bye.....

Hi,


You must draw the fan blade curved in standart option.Themchange to seetmetal (aplications\seetmetal)to take development of the blade you ned curve off the blade. (feature\create\seetMetal\Unbend)


Note: excuse me because my English is not very weel. I hope you understand me.


Bye


Note: I am from Spain and I am workink in Industrial Fans company.

hi,





sorry can anyone give more detail on this? never used sheetmetal applications and dont know what you mean by dtm curves or how you do it?

 

[tobbo]

you dont need sheetmetal for this.... Are you familiar with surfacing? Or do you know how to manage a rotational blend? (and it can also be done with VSS)

here is a VERY "quick and dirty" fanmodell . Just so you get an IDEA of one way to do it.

Surfacing will give you the best results. However, first you have to draw 4 boundary curves that will outline the shape.
Each curve can be determined by two views, that is you draw a line in for example Front Plane-Extrude as Surface-this will give you Surface 1.
Then you draw a second line from either Top or Side plane and extrude it as a Surface 2
The intersection of Surface 1 and Surface 2 will give you one of the boundary curves.
You may have to follow same approach for other boundary curves
