Guest Hendrik Posted April 12, 2005 Share Posted April 12, 2005 Hello everyone, I have to draw a truss with inventor and i hav no idea how i can do this the best way. I want to draw it in such a way that i can easily modify the angle of the braces, the number of braces, the lengthe of the main chords etc... drawing of a truss: http://members.home.nl/hendrikwitting/truss.jpg I know how to draw a truss in solidworks, i sketch the braces in 1 sketch and afterwards i place structural members on top of them, a repetition, and voila, the truss is ready. I also know of a add-in program for inventor called vectrasteel http://www.vectrasys.com With the help of this program you can place structural members in a similar way as with solidworks. However, is there a way to draw a truss without using this add-in??, or do you HAVE to make workplanes for EVERY brace? Many thanks in advance Hendrik Witting Quote Link to comment Share on other sites More sharing options...

Mr T Posted May 9, 2005 Share Posted May 9, 2005 Not been around since I was flamed......... Just draw a spar, then start an Assembly. Now assemble and mate/cosntrain each spar. Bear in mind that you would have to have holes in the three main tubes. Or weld them. Nick Quote Link to comment Share on other sites More sharing options...
caddman6425 Posted April 20, 2011 Share Posted April 20, 2011 I've got a Truss Creator routine that I wrote. Putting finishing touches on it. Respond to nah@truevine.net Quote Link to comment Share on other sites More sharing options...
MarkFlayler Posted April 20, 2011 Share Posted April 20, 2011 What's wrong with using Frame Generator with a Skeletal Part? That works fine for me. Otherwise you can use iCopy with an Adaptive Assembly with spar components. Quote Link to comment Share on other sites More sharing options...
caddman6425 Posted April 20, 2011 Share Posted April 20, 2011 I don't use inventor, I use ACA 2012. So what is this frame generator, something in Inventor only? Quote Link to comment Share on other sites More sharing options...
JD Mather Posted April 20, 2011 Share Posted April 20, 2011 I don't use inventor, I use ACA 2012. So what is this frame generator, something in Inventor only? Frame generator is standard in Inventor (I didn't look at original information since it wasn't posted here). It works essentially the same as in SolidWorks, exept that in Inventor you place the skeleton in an assembly and place the frame members in assembly while in SWx you do in a single part file and then push out the individual parts.

JD Mather Posted April 20, 2011 Share Posted April 20, 2011 I suppose you could work something up in obsolete AutoCAD ( http://home.pct.edu/~jmather/content/CAD238/AutoCAD%202007%20Tutorial%208.pdf), but not sure it is worth the effort since modern tool already exists.

caddman6425 Posted April 20, 2011 Share Posted April 20, 2011 OH, OK. I like that, too bad ACA doesn't have that Quote Link to comment Share on other sites More sharing options...
abccad Posted May 17, 2011 Share Posted May 17, 2011 Is it possible to analyze a 2D Truss structure using the "Frame analysis" module? I have added constraints to all nodes ( to allow Z rotation. ) But besides axial stress, I am also getting bending stress on the members. Do I need to use the "Release option" on the Truss members? It is unclear to me with the Inventor online help. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 17, 2011 Share Posted May 17, 2011 Have you gone through this book? http://www.amazon.com/Wasim-Younis-step-step-engineering/dp/B004VG3STE/ref=sr_1_5?ie=UTF8&s=books&qid=1305629345&sr=1-5 Quote Link to comment Share on other sites More sharing options...
abccad Posted May 17, 2011 Share Posted May 17, 2011 I have ordered the book; but from the TOC, I didn't see the Truss analysis. The analysis results are showing additional bending stress, which shouldn't exist in Trusses. Anybody has done "Truss analysis" in Inventor?
