Professionals such as product designers, architects, and engineers have an intrinsic relationship with drawing, using it to represent everything from the creative sketches of a proposal to its production. In this sense, technical drawing and sketching techniques are a relevant part of design education. In this context, this article presents an analysis of drawings developed by product design students from different countries working in the Global Studio 2018, an international interinstitutional project. In this edition, undergraduate product design students from five universities from four countries (Brazil, Italy, Japan and Turkey) worked in sixteen paired teams, simultaneously playing the roles of "client" and "designer". This study deals with the work of three teams from a Brazilian university and its paired teams, one from Japan and two from Turkey. To support this study, nine categories of analysis were used: Type of drawing; Material used; Quality of the Trace; Presence of Text; Scale; Drawing Communication; Differences and similarities in the drawings of the teams of each country and between members of the same team. In some cases, students used drawings as mere illustrations for detailed textual descriptions of their design concepts. In others, they presented their design concepts by isometric drawings and frontal visions, using texts only as complementary information. The results allowed to identify how the students articulated different forms of drawing for the same purpose.
