我很菜，请朋友们帮助：
我一直对Osnap函数不理解，请教，两个点到底是什么关系？

The osnap function can find a point by using one of the AutoCAD Object Snap modes. The Snap modes are specified in a string argument.
The following call to osnap looks for the midpoint of an object near pt1:
(setq pt2 (osnap pt1 "midp"))
The following call looks for the midpoint, the endpoint, or the center of an object nearest pt1:
(setq pt2 (osnap pt1 "midp,endp,center"))
In both examples, pt2 is set to the snap point if one is found that fulfills the osnap requirements. If more than one snap point fulfills the requirements, the point is selected based on the setting of theSORTENTS system variable. Otherwise, pt2 is set to nil.

(setq pt2 (osnap pt1 "midp"))
就相当于命令当中打了midp,并在pt1上点下，而捕捉到的中点,并设成pt2。
依此类推.
