Basic functions of two-dimensional CAD
① Plane drawing: Basic graphic objects such as lines, circles, ellipses, circular polygons (regular polygons) and spline curves can be created by various methods.
(2) Drawing assistance: provide drawing assistance such as orthogonality, object capture, polar axis tracking and capture tracking. Orthogonal function is convenient for users to draw horizontal and vertical straight lines, object capture can help pick up special points on geometric objects, and tracking function can draw diagonal lines and locate points in different directions more conveniently.
③ Editing graphics: CAD has powerful editing function, and can move, copy, rotate, arrange, stretch, lengthen, trim and scale objects.
④ Size: Various sizes can be created, and the appearance of the size can be set by yourself.
⑤ Writing characters: You can easily write characters in any position and direction, and you can set the font, tilt angle and width scale of the characters.
⑥ Layer management function: The graphic objects are all located on a certain layer, and the characteristics such as color, line type and line width of the objects can be set.
⑦ 3D drawing: 3D solid and surface models can be created, and the entity itself can be edited.
⑧ Network function: You can publish graphics on the network or access AutoCAD resources through the network.
