According to the national standard, the drawing frame must be drawn with thick solid lines, with or without binding edges, but only one format can be used for drawing the same product. Whether there are any drawings with binding edges, the frame format is shown in the figure below, and the frame size is shown in the figure below:
On the left is the reserved binding edge, and on the right is the schematic diagram of the drawing frame without binding edge.
The orthogonal function of the national standards of Technical Drawing and Mechanical Drawing is convenient for users to draw horizontal and vertical straight lines. Object snapping can help to pick up special points on geometric objects, while tracking function can draw diagonal lines and locate points in different directions more easily.
Writing text: You can easily write text in any position and direction of the graph, and you can set the font, tilt angle and width scaling of the text.
Layer management function: graphic objects are all located on a certain layer, and you can set the color, line type, line width and other characteristics of the objects.
3D drawing: 3D solid and surface models can be created, and the solid itself can be edited.
Network function: you can publish graphics on the network or access AutoCAD resources through the network.
