Thanks a lot sir, a great help for beginners.Sir I have a question plz. Sir in your bolt connection portion of presentation it is not cleared to me that we will delete the "Global contact (Bonded defined by Solidworks in an assembly)" to define the new bolt connectors and to define the no penetration contact set between two joining plates (Joined with help of bolts). Suggestion required.I can provide you my solidworks file on your demand.
