创建特定于条目的宏

本例说明如何创建使用用户定义的间隙值对已选刀具路径进行碰撞检查的宏。该宏将：

• 需要用户输入 PowerMill 用于对刀具路径进行碰撞检查的夹持间隙。
• 显示它正在处理的刀具路径的名称。
• 在碰撞检查完成时显示一条消息。

Function Main(
STRING $Selected_Toolpath
) 
{
	// Create new project parameter to store the holder clearance
	BOOL $chk = 0
	$chk = ERROR $project.clearance
	if $chk {
		// Project variable does not exist. Create it and set it to 5 degrees
		EDIT PAR CREATE REAL "clearance"
	}
	// Before checking the first toolpath, PowerMILL should ask the user to enter the holder clearance
 	IF($powermill.Status.MultipleSelection.First) OR $powermill.Status.MultipleSelection.Total == 0 { 
 		$project.clearance = INPUT ${"Enter the holder clearance PowerMILL uses when checking the " + $powermill.Status.MultipleSelection.Total + " selected toolpaths for collisions "} 
	}
	// Now collision check toolpath with entered clearance
	// Set the clearance:
	EDIT COLLISION HOLDER_CLEARANCE $project.clearance
	// Now check the toolpath for collisions
	EDIT COLLISION TYPE COLLISION
	PRINT = "Processing toolpath " + $powermill.Status.MultipleSelection.Count 
	EDIT COLLISION APPLY
	// Tell user all selected toolpaths have been checked
	IF ($powermill.Status.MultipleSelection.Last) {
		MESSAGE INFO "All toolpaths have been checked "
	}
}

输入所有行，且不带换行符。由于页面宽度有限，这里的有些行看起来像包括换行符。
