I've just started learning SolidWorks, and am trying to learn how to do weldments. The problem is I don't have the Weldment tab (see image below). There's a weldment toolbar available, but it doesn't seem to have all the tools available on the tab. I'm using the Student version of SolidWorks. Is the weldment tab not available in this version, or is there a way to enable it?
