1. The reason why I asked that question is rather for me selecting that bottom surface of the nearly 30 red small plate by rotating the truss, then selecting the bottom surface. I thought i would just select the solid red member without compromising the results.
2. is there a way to do it in a group fashion? Meaning to select one red plate bottom surface, then have ansys in a group fashion select bottom surface of all the other small plates in the model, then apply this bonded contact individually for each. I have many members and i don't want to spend the time to do individually for each one if i can do it in a group fashion.
3. You stated in the other post "one of the advantages of having a worksheet view is you can easily modify your selection of contact regions in the Worksheet ". What do you mean by a worksheet view or where is it?
