Thank you for the hints. It's not the only one button missing. The whole bar was not shown and I am not sure why this vase look like icons are not showing at all... and that's why I install all this plugins whit hope, one to repair the problem but for now I am not finding the solution for this problem.
Thank you all for help. It is not so urgent or important for now. I still use Blender and the new found CAD plugin that extend the ability for object creation.
