What is a VSDM file?
Macro-enabled drawing created with Visio, a technical drawing program; serves the same purpose as a .VSDX file, except it allows VBA (Visual Basic for Applications) macros to be stored and executed when the drawing is opened.
Visio macros are used to automate repetitive drawing tasks such as setting shape sizes and positions or setting page formatting options. They may be written from scratch with VBA source code or recorded as a series of user actions ().
