Easily draw shapes such as lines, circles, and arcs, and easily edit and modify shapes with just a touch of the shape. Angle constraints can specify commonly used angles of 5 º -90 º. Snap endpoints, midpoints, vertical points, tangents, and intersections, allowing you to draw accurately. There are also dynamic auxiliary points that provide you with dynamic assistance when drawing each line. The numeric keypad can accurately specify distances during drawing or modification. Drag the dimension edit point to convert it to horizontal or vertical dimensions. Angle annotations, radius annotations, and arc annotations can all rival the excellent performance of desktop applications in creation or editing. Layer management, displaying or hiding layers, and locking layers. Annotation management can add annotation styles, modify annotation styles, colors, line widths, and other annotation shapes. The drawn drawings can be exported as PDF files or DXF data exchange files, and can be shared on the computer and opened using AutoCAD. Thank you very much to Graziano from Italy for providing Italian language translation and Сергей Ломонос Provide Russian translation.
