CAD is an automatic computer-aided design software produced by Autodesk Company in the United States, which can be used to draw two-dimensional drawings and basic three-dimensional designs. You can draw it automatically without knowing how to program it. CAD is widely used in the world, which can be used in many fields such as civil construction, decoration, industrial drawing, engineering drawing, electronic industry, garment processing and so on. No matter what field you want to work in, you can learn CAD by yourself. Here are the basic introduction of CAD, intermediate advanced, advanced and advanced video tutorials. Yutu is committed to helping friends quickly master the use of CAD.

The display effect of the selected edge in different coloring modes is shown in the following figure.

Select sub-objects on a composite 3D solid.

Hold down the Ctrl key to select faces, edges and vertices on the composite solid formed after Boolean operation. If the History property of the composite entity is set to Record (On), the history subobject can be selected for the first pick. (A historical subobject is a part of the original object deleted in a union, difference, or intersection operation. You can select a face, edge or vertex on the original shape by holding down the Ctrl key and picking again.

If a sub-object selection filter is set, you can select faces, edges or vertices by clicking once.
