A file is loaded into memory when you load the file in your SolidWorks session (SldWorks::OpenDoc6) or open an assembly that already contains the file.就是說(shuō)你想指定的插入的文件必須在調(diào)用函數(shù)之前已經(jīng)在內(nèi)存中加載了。Errors, amp。按照上面的要求我們?cè)谙蜓b配體中插入一個(gè)零部件時(shí),需要這樣步驟:得到裝配體使用opendoc6打開(kāi)需要插入的零件使用addponent4插入零件到裝配體我們上面的程序需要這樣來(lái)修改一下,添加了一個(gè)打開(kāi)文檔的函數(shù):39。 insertpart 03/21/05 by arden39。前提條件:在裝配體所在文件夾中有零件“零件1”存在,并且零件1有配置“配置1”39。 openYSB (pth) ‘在添加零部件之前,先打開(kāi)它 pth, 配置1, 0, 0, 0End Sub39。在一個(gè)裝配體中自動(dòng)判斷插入合適的零件,并添加配合。 下面只介紹怎樣進(jìn)行配合 在做配合時(shí),需要經(jīng)常選擇到零件的面、線等,這是一個(gè)問(wèn)題,還有就是介紹一下addmate2函數(shù)的使用: 一般進(jìn)行配合我們按照下面的次序來(lái)進(jìn)行: ‘取消所有選擇 2選擇需要配合的實(shí)體(entity) 3使用AddMate2函數(shù)進(jìn)行配合 4再次使用 ‘取消所有選擇 主要的問(wèn)題在于如何選擇合適的面: 由于面的命名沒(méi)有什么規(guī)律,很多時(shí)候是程序自動(dòng)來(lái)命名的,這樣,不方便使用selectbyID來(lái)選擇,我也不想使用坐標(biāo)值來(lái)選擇一個(gè)面,那樣做更加糟糕。錯(cuò)誤處理 MsgBox 選擇零件失敗 selectface = False Exit Function End If Set swDCface = ‘得到第一個(gè)面 Do While Not swDCface Is Nothing ‘遍歷各個(gè)面 Set swDsurface = ‘得到表面對(duì)象 If Then ‘如果是圓柱面 If tp = 0 Then 39。means plane Set swDEnt = swDCface True, selDdata selectface = True Exit Function End If End If Set swDCface = Loop End Function 此函數(shù)接受兩個(gè)參數(shù),第一個(gè)是一個(gè)ponent對(duì)象,第二個(gè)用來(lái)標(biāo)識(shí)選擇類(lèi)型:0表示圓柱面,1表示平面。需要注意的是我們需要在判斷面類(lèi)型時(shí)候需要轉(zhuǎn)換到surface對(duì)象。可能這個(gè)過(guò)程有些復(fù)雜,大家按照這個(gè)順序多測(cè)試幾次,就明白了它的工作原理。 下面介紹一下addmate2函數(shù): Syntax (OLE Automation) OLE語(yǔ)法: pMateObjOut = ( mateTypeFromEnum, alignFromEnum, flip, distance, distAbsUpperLimit, distAbsLowerLimit, gearRatioNumerator, gearRatioDenominator, angle, angleAbsUpperLimit, angleAbsLowerLimit, errorStatus ) 參數(shù): Input: (long) mateTypeFromEnum Type of mate as defined in swMateType_e 配合類(lèi)型 Input: (long) alignFromEnum Type of alignment as defined in swMateAlign_e 對(duì)齊選項(xiàng) Input: (VARIANT_BOOL) flip TRUE to flip the ponent, FALSE otherwise 是否翻轉(zhuǎn) Input: (double) distance Distance value to use with distance or limit mates 距離 Input: (double) distAbsUpperLimit Absolute maximum distance value (see Remarks) 距離限制max Input: (double) distAbsLowerLimit Absolute minimum distance value (see Remarks) 距離限制min Input: (double) gearRatioNumerator Gear ratio numerator value for gear mates 齒輪配合分子值 Input: (double) gearRatioDenominator Gear ratio denominator value for gear mates 齒輪配合分母值 Input: (double) angle Angle value to use with angle mates 角度 Input: (double) angleAbsUpperLimit Absolute maximum angle value 角度限制max Input: (double) angleAbsLowerLimit Absolute minimum angle value 角度限制min Output: (long) errorStatus Success or error as defined by swAddMateError_e 錯(cuò)誤報(bào)告 Return: (LPMATE2) pMateObjOut Pointer to the Mate2 object 返回指向配合的指針 Remarks To specify a distance mate without limits, set the distAbsUpperLimit and distAbsLowerLimit arguments equal to the distance argument39。但這樣做是影響了效率。并且第三個(gè)參數(shù)和第二個(gè)參數(shù)需要按實(shí)際情況來(lái)確定。特征下的草圖在solidwork中其實(shí)是特征的子特征,我們可以對(duì)特征進(jìn)行GetFirstSubFeature、及GetNextSubFeature得到。代碼是solidworks的示例文件,只是向用戶(hù)顯示程序執(zhí)行的結(jié)果。39。 Postconditions: None39。 Bold = amp。 CharHeightInPts = amp。 Escapement = amp。 Italic = amp。 LineSpacing = amp。 Strikeout = amp。 Underline = amp。 Vertical = amp。 End SubFunction TransformSketchPointToModelSpace _( _ swApp As , _ swModel As , _ swSketch As , _ swSkPt As _) As Dim swMathUtil As Dim swXform As Dim nPt(2) As Double Dim vPt As Variant Dim swMathPt As nPt(0) = : nPt(1) = : nPt(2) = vPt = nPt Set swMathUtil = Set swXform = Set swXform = Set swMathPt = ((vPt)) Set swMathPt = (swXform) Set TransformSketchPointToModelSpace = swMathPtEnd FunctionSub ProcessSketchLine _( _ swApp As , _ swModel As , _ swSketch As , _ swSkLine As _) Dim swStartPt As Dim swEndPt As Dim swStartModPt As Dim swEndModPt As Set swStartPt = Set swEndPt = Set swStartModPt = T
