Briefly talk about the basic functions of CAD software

The following uses AutoCAD as an example to briefly introduce the basic functions of 2D CAD. ·

Plane drawing: can create basic graphic objects such as straight lines, circles, ellipses, polygons, and splines in a variety of ways. ·

Drawing auxiliary tools: Provides orthogonal, object snapping, polar tracking, snap tracking, etc.

Drawing auxiliary tools. The orthogonal function allows users to easily draw horizontal and vertical straight lines, object snapping can

help pick up special points on geometric objects, and the tracking function makes it easy to draw diagonal lines and locate points in different directions. Easier. ·

Edit graphics: CAD has powerful editing functions that can move, copy, rotate, array, stretch, extend, trim, scale objects, etc. ·Annotation dimensions: Various types of dimensions can be created, and the appearance of the annotation can be set by oneself. ·

Writing text: You can easily write text at any position and in any direction of the graphics. You can set the text font, tilt angle, width scaling and other attributes. ·

Layer management function: Graphic objects are all located on a certain layer, and the layer color, line type, line width and other characteristics can be set. ·

Three-dimensional 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. ·

Data exchange

: Provides a variety of graphics and image data exchange formats and corresponding commands.
