常用

黑色线框:

把场景中所有几何体的线框颜色设置为黑色

清空选择:

清空选择。如果被选择物体处于子对象状态，将切换到父对象并取消选择。

Copy:

Copy selected objects.

Paste:

Paste objects stored by Copy tool to the scene,if right-click in view,the new objects will retain their origin positions .If left- click in the scene,the new objects will move to new position.

DelEmptyObj:

Delete the objects that have not any

Dwg文件输入:

Dwg文件一键导入，工作原理是读取在AutoCAD中保存的块文件。
1.在CAD中，使用块文件写入功能（WBLOCK 快捷键为"w"）把被选择的物体保存为一个Dwg文件，默认名称一般是"new block.dwg"或"新块.dwg"。
2.在利斧的管理工具中，打开利斧设置，在【AutoCAD输入】中查找到第一步保存的dwg文件以保存文件夹和文件名；
3.为了确保单位能准确转换（如cad中的单位设置为毫米，而max中的单位为米），单击【导入测试】按钮，打开【AutoCAD dwg/dxf Import Options】窗口按自己希望的进行设置。
完成以上设置后，就可以使用该命令进行一键cad导入了

PivotCenBot:

Set pivot of each selected object to it's bottom center.

PickPivot:

Snap a point and set it as current object's pivot.

ConnectKnots:

Connect two selected vertices of a spline shape.

FlatShp:

Flatten all selected spline shapes.

线条焊接

将线条内所有位于端点的顶点进行焊接操作，用于消除不易察觉的断点。使用此工具时，会选择所有子线条的端点。

FreeLine:

Free to draw spline shape.

曲线逆时针

将线条内所有闭合子线条转换为逆时针走向；

线条细分

根据线条曲率以及设定的最小距离对曲线进行细分。一般情况下，由线条直接转变生成的多边形，会经常出现圆角处顶点密集或者过于稀疏的情况，需要后续的圆整操作来改善模型。使用此工具可以获得较为合理的顶点密度，减少后续的工作量。
顶点密度的控制同自动圆角和线拼图，可打开管理->圆弧vs段数预设进行设置。

Base on allowed min distance and curvatures of each segments to subdivide selected spline shapes.

Explode:

Explode selected object,if Editable poly,then detach each element as a single object;if splineshape ,will detach each spline.

MoveObjs:

Move selected objects from one point snapped to another one.

DropToGrnd:

Move each selected object along z-axis to ground surface .

DropToGrndZN:

Move each selected object along z-axis and normal align to ground surface.

RefRotate:

Rotate selected objects like in AutoCAD,Snap first point as rotation center,second point with first define start angle,snap third point with first as rotation end.
