Break all across points.
 
  Program name : BCROSS.LSP

   This program is designed for a specific purpose rather than a general purpose. 
But I introduce it to civil engineers who feel uncomfortable like me. 
When we use structural analysis program, we model with grid or SHELL element. 
Almost of analysis program can import DXF file that is create by CAD. 
If analysis program can't recognize arc like left figure below,
You should draw like a right figure . 
You have to pay for it. So this program breaks the intersections of the model figure consisted of ARC and LINE 
and Analysis program can import them. ARC entities are converted to lines.  


  
 Example-1
select entity :                 [Select entities. (ARC or LINE are possible)]
base point:                     [Pick base point]
destination point:              [Pick destination point] 


  



This program does not actually cut the selected entities, 
but uses the information of the selected entities to create another entities. 
We need a base point and a destination point. 
The reason for this is to create a new model with the original. So You can modify original entities.
