Why not to replace screw thread with bonded contact?

maybe i do not understand you, prabhakaran.
Do you wand to draw some details in your model using abqs tools? i think you are searching difficulties=)
Does it possible to use CAD software?
abqs is powerfull solver but it has a weak preprocessor to my mind.

ok. why do you need this one-it's another question=)
you can do it in CAD software. I'm not CAD engineer, i do not use CAD software. i use preproccessors-BETA CAE, HM.
