Angle Constraint / Drive Constraint Issues

Hi everyone,

 

I am designing a vertical axis wind turbine just for some practice (just started using Inventor) and everything was going smoothly until I tried to "animate" it spinning.  First, I set up a work plane that goes through the center of the structure, and then I clicked angle constraint "explicit reference vector." After watching several youtube videos, I figured that I should click on the work plane, click on another reference point, and then click another point that would be orthogonal to those two (right?). Well after I choose the first point, Inventor will only allow me to choose the center axis  as the second option (which I think should be the third option).

 

Regardless, no matter what I do it won't work. 

 

Has anyone else experienced this? I attached the file if anyone would like to give it a go.

 

Cheers

Drew

First of all an assembly file without part files is useless.

You should not need to create the workplane - use one of the origin planes.

Sorry about that! 

 

It will only allow me to upload three attachments, and the assembly contains 5 different part files. I will post 3 in this post and 2 in the next. Please let me know if there is a better way to do this!

Inventor complains about the missing files:

VAWT structure.iam

Shaft1.ipt

SKFEE 3ANSI.ipt

locking collar.ipt

 

when I try to open the attached assembly. Could you create a zip file of all missing components (and upload it), so I could take a look at it?

I did a "pack and go" (love that name)  and then compressed all those files into a zipped folder. Hopefully this will work!

Thanks

One of the ways to animate your turbine is creating two workplanes. One by selecting Shaft:1\Origin\XY Plane. This workplane will be attached/constrained to your Shaft:1. Create another one constrained to VAWT structure:1. Since both workplanes will share the same shaft axis, you can easily constrain them by angular constraint. Then you drive the constraint as needed.
