solidworks二次開發-02-用來訪問特征的兩個api
來學習兩個api：

selectbyid2和getselectedobject5。這兩個函數，第一個通過給出對象的name選擇對象。第二個通過啟用程序前已經選擇的索引得到對象。

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

' 選擇叫"拉伸1"的特征

boolstatus = model.extension.selectbyid2("拉伸1", "bodyfeature", 0, 0, 0, false, 0, nothing, swselectoptiondefault)

'主要就是這一句話，在寫option explicit后函數的最后一個參數swselectoptiondefault可以使用0來代替

' 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”這個特征下面的代碼將其選中

    dim selmgr as selectionmgr

    set selmgr = model.selectionmanager

    set feature = selmgr.getselectedobject5(1) '此處使用一個索引來得到特征

    debug.print feature.name

else

    debug.print "error"

end if

end sub

最后列出這兩個函數的vb語法：

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

if...

and if entity is...

then...

true

not already selected

the entity is appended to the current selection list

already selected

the entity is removed from the current selection list

false

not already selected

the current selection list is cleared, and then the entity is put on the list

already selected

the current selection list remains the same

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

也可以通過com使用vc來訪問。
