Uniting components in an assembly.

[fernandomierhicks]

Hi:

I was wondering if anybody knew how to join components in an assembly, the reason of this is because, inventor cannot do a FEA in assemblies or various components so I was planning on joining all the parts in an assembly to make it a single .ipt and then apply the forces and see the FEA.


Thanks

Save the assembly as a .SAT or .STEP file. There is an option when saving to combine into a single solid or individual components.

I did what you said but now the problem is that inventor import's the assembly as a composite a single composite, and in the stress analysis menu it does not let me do anything, all the buttons appear disabled, do you know a workaround for this?

thanks

Forget all that; Open a new Part File, exit the sketch and use the Derive Component command, this will derive the assembly into a single part which you will be able to do FEA on.

Now that being said; IV2010 does do FEA on Assemblies and either way you spin what you are doing it is not an exact representation of FEA on an assembly but may give you a good idea of your design intent.

Autodesk Labs has/had a free add on for Professional users that will FEA assemblies.

Not anymore, they pulled it because the technology is in 2010 and more well refined. I still have the installer, but if this is a big part of your work you should jump to 2010.

I have 2010, but I'm waiting for a service pack to be made. If I blink my eyes, it crashes.

I have 2010, but I'm waiting for a service pack to be made. If I blink my eyes, it crashes.

I'll bet money that it is a hardware problem or some software other than Inventor that is causing the problems. What does your VAR say about your install?

2010 is VERY stable. If you are constantly crashing you have other hardware/driver problems. or simply a bad install

I also used to wait for service packs but stopped when 2008 came out and have not had more than 2-3 crashes a year.

I also run a good cleanup/refresh of my computer before each install. Run virus,run spyware,defrag, delete temp files, update all drivers including bios flash,etc...

Autodesk has indicated a large majority of crash reports are submitted because of graphics card issues...
