Hi,
Sometimes 2D analisys is more than enough, specially if you try to train students in basics of FEA.
I can understand that ANSYS and some others don't have a good 2D sketch modules and it is a pain create 2D models but, why is also true in the Simulation Mechanical case?
You have the technology in products like Inventor and it is so easy and fast create an accurate 2D sketch in these products, please put it in Simulation Mechanical!
Thanks,
Miguel Ángel Agustín
