Making gears hook in to each other

[Anonymous]

Hi

I am a beginner at inventor and for my first school project i need to make a planetary gearbox but I can't seem to get the gear hook in to each other. Is there someone how can help me with this problem.

Thanks in advance.

Yes, attach your assembly here.

(BTW - this is the third student this week with planetary gear assignment.  Has your instructor given you the necessary instruction to complete the assignment?)

The files that I send is all that I got for now. And no the teacher is not giving us any information.

I've got to find me one of those jobs - getting paid as a teacher to not teach anything.

Back in a few minutes with your assembly.

Okay thank you I also have a problem with the ring gear because when I calculeted it it doesn't fit the rest. Can you help me with that two ? 

Thanks in advance

Well, either I got your files confused with one of the other students - or you have a ring gear with a helical twist angle while the others are straight spurs.

No this are my files it seems to work now so thank you very much you really saved me thanks.

What age group is this?

Have you been taught how to fully constrain a sketch?

 I say high school. One of my clients son is doing this as well. And no they teach nothing. He gave me one of his files and I was like what the #@^&.. this is his second year and he came to me today and ask how to constrain parts in a assembly.

 I thinks the idea is to give kids a cool toy but not teach them how to use it..

It is the last year in high school. But we have not seem how to do constaints correct.

... and that's what they call discovery learning.  It's expected the students will figure out on their own (!) several different ways of doing things.  The instructor isn't there to show them how it should be done (there is no "right way" in this process), they're only there to help the students "explore".  Fine for arts, stage, etc. but an absolute disaster for the technical courses.
