WOW!!!!

That really does take a beating. Guess I now know what is the strongest part of the robot.

That was the original plan, but there isn't really enough room... I could always make the chassis bigger than 35 x 25...

Pretty much yes.

The only problem is wood is not an option to choose from.. And I don't if you can manually change the density in Inventor...

You can. I forget how, but you can. And if wood isn't an option, then I just lost respect for Inventor. You go into the properties, and pick your type of wood--pine or oak should do the trick. (It doesn't have "wood" as an option because every wood is a different type of wood, and has a different density.)

Somehow we modeled ours in Inventor last winter...huh....

I went through all materials. Not a single type of wood. In the 2009 Inventor There was. They were listed as "Wood (Pine)" or "Wood(Oak)". But when they upgraded to 2010 they must have take it out...

It is possible to just change the texture (As I did). But odds are you made it in 2009.

Are there certain add-ins that you don't have enabled? I don't use Inventor but just a suggestion.

I don't remember exactly where it is, but in the iProperties of a part you can change the density to a custom value.

No. All the other add-ins not enabled are just converters for other CAD programs..

I went through all the IProperties.. Couldn't find it...


I think its time to switch to solidworks..

[MrForbes]

You definitely want to be using a wood friendly modeling program. Wood is where it's at.

[Rion Atkinson]

Maybe I'll switch back to Inventor 2009 until I can get solidworks somehow....

Just to Support Solidworks. One of the main benefits with Solidworks is that it is used more in the industry. In our area 12 out our 15 sponsoring (Engineering Companies) companies use Solidworks. Most of their partners use it also.

Also Solidworks has a wide range of add ins and the workflow is Fantastic. If you want a Copy of Solidworks, Marie Planchard would be the person to contact, Solidworks Rep for FIRST.
