用脚本进行三维造型

发布时间:2022-07-27 13:56:13

昨天有幸申请到AnyCAD Part Editor(一个脚本三维建模软件,官方介绍见此)的内部版本,使用了一下,感觉很小很强大。

以下是使用手记。

建立基本的三维基本体

用它建立基本的三维基本体,如:

圆柱

topoShape = theBrepTools:MakeCylinder(Vector3(0,0,0), Vector3(0,0,1), 30, 50, 0)
idx = theEntityGroup:AddTopoShape(topoShape)

  

topoShape = theBrepTools:MakeSphere(Vector3(0,0,0), 100)
idx = theEntityGroup:AddTopoShape(topoShape)

  

长方体

topoShape = theBrepTools:MakeBox(Vector3(0,0,0), Vector3(0,0,1), Vector3(50,50,80))
idx = theEntityGroup:AddTopoShape(topoShape)

圆台

topoShape = theBrepTools:MakeCone(Vector3(0,0,0), Vector3(0,0,1), 100,50, 50,0)
idx = theEntityGroup:AddTopoShape(topoShape)

等等,还有其他。

二维基本体

-- Circle
topoShape = theBrepTools:MakeCircle(Vector3(0,0,0), 100, Vector3(0,0,1))
theEntityGroup:AddTopoShape(topoShape)
-- Arc
arc = theBrepTools:MakeArc(Vector3(-50,0,0), Vector3(0, 50,0), Vector3(0,0,0))
theEntityGroup:AddTopoShape(arc)
-- Spline
pt1 = Vector3(0,0,0)
pt2 = Vector3(50,0,0)
pt3 = Vector3(100,30,0)
pt4 = Vector3(150,100,0)
pts = Vector3List()
pts:Add(pt1)
pts:Add(pt2)
pts:Add(pt3)
pts:Add(pt4)
spline = theBrepTools:MakeSpline(pts)
theEntityGroup:AddTopoShape(spline)

三维特征操作

拉伸

arc = theBrepTools:MakeArc(Vector3(-50,0,0), Vector3(0, 50,0), Vector3(0,0,0))
extrude = theBrepTools:Extrude(arc, 100, Vector3(0,0,1))
idx = theEntityGroup:AddTopoShape(extrude)

  

扫略

-- Section
circle = theBrepTools:MakeCircle(Vector3(0,0,0), 10, Vector3(1,0,0))
edgeGroup = TopoShapeGroup()
edgeGroup:Add(circle)
wire = theBrepTools:MakeWire(edgeGroup)
-- Path
pt1 = Vector3(0,0,0)
pt2 = Vector3(50,0,0)
pt3 = Vector3(100,30,0)
pt4 = Vector3(150,100,0)
pts = Vector3List()
pts:Add(pt1)
pts:Add(pt2)
pts:Add(pt3)
pts:Add(pt4)
spline = theBrepTools:MakeSpline(pts)
sweep = theBrepTools:Sweep(wire, spline)
theEntityGroup:AddTopoShape(sweep)

  

回转体

arc = theBrepTools:MakeArc(Vector3(-50,0,0), Vector3(0, 50,0), Vector3(0,0,0))
revol = theBrepTools:Revol(arc, Vector3(0,0,0), Vector3(1,0,1), 300)
theEntityGroup:AddTopoShape(revol)

  

其他等等...

文件导出

这个软件支持把建立好的模型导出为STL,IGES,STEP,因而可以在SolidWorks,UG里面打开了。

总结

上手有点难度,但掌握了就很好用。
