Hi Ranga....

Why you create your weldment as assy ?
Why you not create as a multi body part ?

  hi designer,
  
  The above is just a sample. In real practice. i use multi body parts only. but still i need to use an assembly made of many multi body parts. Because my structures contain many members which cannot be shown in a single model.

  send me that weldment part.
  i will send u the solution.
  in beam mesh first we have to select the beam structures.
  then software calculate the joints automatically.

    hi,
    
    i have chosen option "treat all weldments as beams". and it detected joints automatically. that is where prob lies.
    
    you can make two identical simple sqaure beam (weldment) parts. assemble them and try to detect joints. please let me know whether it detects properly.
    
    thanks

        i am very sorry.
        i tried that beam mesh using assembly.
        i got same results.
        4 joints created. but only 2 joints are visible.
        my opinion is beam mesh only for weldment . not for assembly
