The Manual Data Input Mode (MDI) is one of the modes your CNC machine can operate in. The idea is to enter g-codes on a line which are executed immediately by the machine–you don't have to write an entire g-code program when a line or two will suffice. You just type in your line of g-code, press a button, and the machine .

Understanding surface roughness symbols. Symbols that indicate the surface texture of machined and structural parts are used in industrial diagrams. The pictorial representation using these symbols is defined in ISO 1302:2002. This section will explain how to write these symbols to indicate surface textures. Terminology explanation
Click the Annotate tab Symbols panel Surface Texture. Select an object to attach the surface texture symbol to. If you attached the symbol to a line, in the drawing area, specify the start point for the leader. If you attached the object to an arc, circle, ellipse or spline, skip to the next step. Specify one or more points to define the vertices of the leader, and then press ENTER.
