CAD software is the backbone software and can be used independently.

Tianzheng software is a secondary development, a secondary development package according to domestic drawing habits. It can only be used by adding Auto CAD, which is equivalent to a plug-in of CAD and cannot be used alone.

2, the drawing speed is different:

CAD is a particularly powerful drawing tool, which contains many tools, and the drawing speed is relatively slow.

Tianzheng contains many quick functions, equivalent to an upgraded version of CAD, which can quickly draw grids, quickly mark dimensions, automatically layer, automatically grab elevations and so on.

3, the types of drawing graphics are different:

CAD software can draw all kinds of graphics with one click, including hydropower, structure, civil engineering, bridges and so on.

Tianzheng can include architectural tianzheng, structural tianzheng and hydropower tianzheng, and different jobs have different quick drawing tools.

Extended data:

Auto cad is developed and produced by Microsoft Corporation of the United States. Its function is very powerful. This is the second development based on auto cad in China.

Professionally speaking, there is a big difference between the two. In wall painting, there is a wall painting toolbar that can automatically close corners or intersections, while auto cad needs to close them one by one.

In different industries. Autodesk and some domestic enterprises have developed some plug-ins based on general cad, such as popular series, Chen Hao series and Tianzheng series. The usability of cad is greatly improved.
