Rigid Bodies Exporting

Hello together,

 

I wanted to export a model to another CAD program and I noticed that the Rigid Bodies didn't arrive in that program. I think only Geometry can be exported. How can I add something at the center of the rigid body that can be seen in any other program, like a little sphere or anything like that? Or ist there a possibilty to transform a rigid into a surface?

 

Thank you in advance!

    You can use TCL script to create (geometrical) lines for each RBE. These lines will found within exported CAD.

    Do you know which TCL Modify Command it is? I can't find something appropriate to do that.

    You do a loop over RBE.

        Foreach RBE, get his ID, dependant nodes, independant nodes,....

             Get coordinates for each node and draw lines

    I made some now by hand but if I'd do all like that, I'd still do it in 2 weeks.

    How do you mean by loop over RBE? As is said I couldn't find any command of dragging a line. And the RBody Manager just shows me the ID of the Master Node, no coordinates..

    Here's my script:

    • Run it
    • Select some RBE
    • Lines are created within comp named 'RBE_Lines'
    • STEP is exported to '*_RBE.stp' in the same directory as HM model

    It's working! Thank you!

     

    Is the same process also available for a Spring2 element?
