What are the specific applications of "point" in CAD? In fact, points have a wide range of applications, knowing that two points can define a straight line, three points that are not on the same straight line can define an arc, and so on. You can set a point style, create a fixed distance bisector on a specified object, or create a fixed digital bisector. The created points can be used as datum points or reference points for other design operations.

* * * There are many point styles, and the default point style is the first one. You can change the style of points by setting two system variables "pdmode" and "pdsize".

There are div-constant division and mea constant division. After bisection, you can capture the bisection point using the capture node in object capture. Po is mainly used to mark points. First, the style and size of points should be set with ddptype command.
