SolidWorks-API-Collision-Detection
Use SolidWorks API to MovePart and Collision Detection 利用solidworks的API来移动控件物体以及进行碰撞检测
visual studio 2022 利用Nuget 安装这些库
打开solidworks
可以看到有两个控件
部件运动
使用封装的函数void MovePart(string partName,double thetax,double thetay,double thetaz, double xDistance, double yDistance, double zDistance,double scale)改变部件partname 是部件名称 比如 床 
他的部件名应该为string partName = “bed2-1”; 您可以参考样例来学习更多的使用；
thetax、thetay、thetaz分别是让物块按照不同的轴转动，您也可以三个都写进行复杂转动，该函数中已经将多角度转动融合了。注意，这里的转动是转动到指定位置，而不是转动多少度。比如你想要30°，60°，您应该直接写对应的角度，而不是运行两次30°。
xDistance、yDistance、zDistance分别是指定轴方向的平移，这个平移经不确定的测量，可能1代表1m的运动距离 这个就是实打实的运动1m，比如你要0，1，2，3m的位置距离，那就多次写入运行1
scale是放缩该部件，这里不做赘述。
连接solidworks
打开solidworks后 连接solidworks 这里我写了一个简单的界面的连接按钮。
连接成功
即可对物块进行操作了，例如 旋转30°
进行碰撞检测
bool CheckForInterference() 调用后如果当前所有界面中有碰撞 那么会返回true 否则返回false
组合运用部件运动和碰撞检测
组合运动上述两个功能，即可用solidworks模拟机械设备运动，并知晓当前位置是否会发生碰撞，最终知道在各个位置是否会出现碰撞冲突，存入数据库，以指导机械运动的安全联锁。
