用脚本进行三维造型-创新互联

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。

成都创新互联专业IDC数据服务器托管提供商，专业提供成都服务器托管，服务器租用，成都电信服务器托管，成都电信服务器托管，成都多线服务器托管等服务器托管服务。

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)

球

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)
