consraints in inventor 2010 studio

[matulja87]

dear people hopefully smarter than me,

 

i need help on trying to run a mandrel down driven by two sprockets. not to be preverted but the assembly looks almost like this........... olo .......... in the assembly i put motion constraints on the sprockets so they run equaly with each other. i also constained the sprockets to match up with knobs on the mandrel. in the assembly when i run the mandrel up and down with my mouse everything works. and i cant figure out how to link those constraints when i switch over to studio. so i can animate the mandrel up and down and have the sprockets follow wichever way the mandrel goes. i need to make a movie for a presentation at work. i just never realy got into studio and am trying to teach myself. if anyone can help please let me know. i would not mind sending more information to help anyone who can help me (screen shots or files) if you want them.

 

thanks

Have you gone through the Help>Learning Tools>Tutorials? Seems to me there is something similar with an Arbor Press.

 

In any case the solution is to add an angle constraint (I like to name it Drive This) between one of the sprockets and a convenient plane. Then in Studio Animate Constraint the angle constraint.

 

If you can't figure it out zip and attach your assembly here.

Wow I never realized those files were there. But I still can't figure it out. I appreciate you helping me out. Let me know if the zip works.

 

Thanks

First thing you should have been taught in your training is that an assembly without parts is useless. The iam is only hyperlinks to the ipt files and a record of assembly constraints.

 

You need to include the ipt part files to have a valid assembly.

oops sory about that JD. i was in a rush yesterday trying to get home. i have three .ipt's to send you which are 462, 356, and 295 kb, which the forum only allows 250 kb. if you want i could send them to a personal e-mail of yours if you want. and i will continue to work on the studio animation and see if i can figure it out. i wonder if i set it up to animate positional representations???

 

thanks

The usual procedure it to drag the red End of Part marker in the feature browser all the way to the top of the browser to hide all features before saving and zipping to get the absolute smallest file size for posting.

At the other end the person answering question simply extracts (unzips) the file and drags the EOP back down to reveal the features.

[matulja87]

i will have to remember that one. well JD i figured it out, i did put positional representations on the assembly and it worked perfectly in studio!!! now if i can just figure out how to make a movie and e-mail it??? i greatly appreciate your help JD i will still try to send files like you said, just for fun.

thanks mark thats some good information. i made a short, crappy, basic movie but i could not save it. i need to be able to send movies through email. is that possible???

 

thanks

mikey

[MarkFlayler]

Yes, you can but the quality will be very low. What you might consider is creating a private VIMEO.com or YouTube account to put them up on. Anything email size is usually very low in quality. Most of the videos you saw in that youtube channel I have range from 8 MB (short) to 138 MB (long)

oops i dint mean to send that specificaly to you. it was ment to be put on the main post page. sory im new at this forum deal. but anywase thanks for more helpfull information.

Have you gone through this document?

Your 10' Mandrel has sick geometry in Sketch4 and the sketches aren't constrained. I would have done this part much differently.

Was the sprocket sketch even created in Inventor? I would have done much differently and pattern features rather than sketch enitites.

[matulja87]

the mandrel was 110' long and i un-extruded a section of it. the sprocket was actually traced, scaned, and sketched in autocad 2008, then copy and pasted(sory)i cheat sometimes. the new sprocket did not need to be 100% correct from the original. they wear down and get thrown away in a SHORT period of time.

 

and i looked through your papers, and that is some good info. i will have to find some time to really go through it well.

 

thanks

Do you realize that you can simply edit the extrusion length? That is the beauty of history based parametrics vs AutoCAD.

[matulja87]

i took a part out of the assembly that should not have been there and fixed the sick geom.
