solidworks二次开发-02-用来访问特征的两个API
来学习两个api：
SelectByID2和GetSelectedObject5。这两个函数，第一个通过给出对象的name选择对象。第二个通过启用程序前已经选择的索引得到对象。
看下面程序：
Option Explicit
Dim swApp As SldWorks.SldWorks
Dim Model As ModelDoc2
Dim feature As feature
Dim boolstatus As Variant
Sub main()
Set swApp = Application.SldWorks
Set Model = swApp.ActiveDoc
' 选择叫"拉伸1"的特征
boolstatus = Model.Extension.SelectByID2("拉伸1", "BODYFEATURE", 0, 0, 0, False, 0, Nothing, swSelectOptionDefault)
'主要就是这一句话，在写Option Explicit后函数的最后一个参数swSelectOptionDefault可以使用0来代替
' If the selection was successful, that is, "Extrude1" was
' selected and it is a "BODYFEATURE", then get that feature; otherwise,
' indicate failure
If boolstatus = True Then '如果有“拉伸1”这个特征下面的代码将其选中
Dim SelMgr As SelectionMgr
Set SelMgr = Model.SelectionManager
Set feature = SelMgr.GetSelectedObject5(1) '此处使用一个索引来得到特征
Debug.Print feature.Name
Else
Debug.Print "Error"
End If
End Sub
最后列出这两个函数的VB语法：
ModelDocExtension::SelectByID2
Description
This method selects the specified entity.
Syntax (OLE Automation)
retval = ModelDocExtension.SelectByID2 ( Name, Type, X, Y, Z, Append, Mark, Callout. SelectOption )
|
Input: |
(BSTR) Name |
Name of object to select or an empty string |
|||||||||||||
|
Input: |
(BSTR) Type |
Type of object (uppercase) as defined in swSelectType_e or an empty string |
|||||||||||||
|
Input: |
(double) X |
X selection location or 0 |
|||||||||||||
|
Input: |
(double) Y |
Y selection location or 0 |
|||||||||||||
|
Input: |
(double) Z |
Z selection location or 0 |
|||||||||||||
|
Input: |
(VARIANT_BOOL) Append |
|
|||||||||||||
|
Input: |
(long) Mark |
Value that you want to use as a mark; this value is used by other functions that require ordered selection |
|||||||||||||
|
Input: |
(LPCALLOUT) Callout |
Pointer to the associated callout |
|||||||||||||
|
Input: |
(long) SelectOption |
Selection option as defined in swSelectOption_e (see Remarks) |
|||||||||||||
|
Output: |
(VARIANT_BOOL) retval |
TRUE if item was successfully selected, FALSE if not |
SelectionMgr::GetSelectedObject5
Description
This method gets the selected object.
Syntax (OLE Automation)
retval = SelectionMgr.GetSelectedObject5 ( AtIndex )
|
Input: |
(long) AtIndex |
Index position within the current list of selected items, where AtIndex ranges from 1 to SelectionMgr::GetSelectedObjectCount |
|
Output: |
(LPDISPATCH) retval |
Pointer to the Dispatch object as defined in swSelType_e; NULL may be returned if type is not supported or if nothing is selected |
也可以通过COM使用vc来访问。
