2009 Controls Inventor model?

[Ellery]

Aren't the components for the CRIO already on the NI.com site - they are iges/step formats that you can import.

Can someone post the links please.

OK, i am just about done with the cRio inventor model that i have been working on all day. If anyone needs i can try to email it to them. It has the overall dimensions fairly close, but it lacks very minor details. For inventor puroposes though it is perfectly recognizeable and very close in overall dimensions.

just email me and i can try to get it to you asap through email, or may have it posted somewhere within the next few days.

Email me Please!!!

Here is the link to the web page listing all of the cRio models available.
http://digital.ni.com/hardref.nsf/di...node=200533_US

Drawings are available in IGES, STEP and ProE formats.

Visually, this looks like the cRio that ours is derived from:

ok, i have my cRio done now, and i can send it to anyone that needs it. Just email me at samir13k@hotmail.com.

As soon as I recieve the Controls kit, I'll start modeling and posting on FirstCadLibrary. These models will be weight accurate and more detailed.

I have updated my model, but for competition purposes you may want to use FirstCadLibrarys version as soon as it comes out. As for now, mine is still available for quick drawings and temporary use if you would like. Just email me. I will warn you that it is not completely accurate. I could not find a fully dimensioned drawing, so i had gone off what i could find.

Nice work. BTW My last post was not intended to be a dig on your model. I was speaking of the generic models on the NI site.

I'm really confused here... didn't the actual models get released through autodesk?

[samir13k]

no offense taken...
Anyways, if you look at FirstBase by autodesk, it says that the drawings will be released around kickoff (from what i can remember). Unforunately, NI's drawings from their website are in IGES form, and you will run into problems with opening them on autodesk. Obviusly, First Cad Library is usually the most reliable source, but they can only make the models after they recieve the parts. This unfortunately means that there are not many usable models out yet. That is why i made my model. It is fairly accurate, so if you want to plug it into an old robots drawings, then it will serve its purpose to show the general area taken up.

Long story short, models will be released eventually, but most are not available yet. Im sure First Cad Library will start theirs asap, but making models is a fairly long process when you reach the precision of them.

Hope that makes sense.

I was just looking at the Pro/E model of the cRIO-9074* from NI's website; it's just a shell that's been filled in with the solidify tool. It will be geometrically accurate, but you won't be able to edit the parametric features.

The STEP file on the website seems essentially indistinguishable from the result of converting the Pro/E file to STEP using Pro/E Wildfire 4.0. That's this:


When imported back into Pro/E as an assembly, the STEP files have some individually selectable parts (like the DE9 on the left), but others are just merged into the whole (like the DE15 housing at the bottom of an expansion slot). Note that there are only 2 out of 8 DE15s depicted—that's annoying.

So, for those of us who want to be accurate in terms of the shape of the device (apart from the omitted D-subs, and with very minor variations from the cRIO-FRC) the NI-supplied model is pretty good. If you're going for the Inventor award, then maybe you'll find it necessary to grab the Pro/E model, duplicate the missing D-subs and graft them on, re-export it as a STEP for Inventor, and then insert the textures and decals (and hope the judges appreciate really nice imported geometry over passable native geometry). Either that, or dig up NI's actual production CAD files and convert them as necessary. And if you want something that is native-Inventor then you're pretty much stuck with modelling it from scratch. I can't see any good reason to use the IGES files.

As for weight, centre of gravity and other properties, I suspect that the best method (for Inventor or SolidWorks at least) would be to hardcode them. If you're using Pro/E, the hardcoding has never really worked right (because of where Pro/E grabs its data from when using model mass parameters in relations or drawings), but it should be good enough within the model itself.

And for anyone looking for some of the dimensions of the cRIO-9074 device, here's a drawing with a few useful dimensions.

*FIRST teams get the cRIO-FRC instead, but it's mechanically similar.
