怎么样用VBA将图幅中的图元筛选出来
怎样用选择集将某个名称的图元筛选出来？请求前辈告知，谢谢。 Sub Example_Select()' This example adds members to a selection set, first by crossing and
' then by filtering for circles.
' Create the selection set
Dim ssetObj As AcadSelectionSet
Set ssetObj = ThisDrawing.SelectionSets.Add("SSET")
' Add all object to the selection set that lie within a crossing of (28,17,0) and
' (-3.3, -3.6,0)
Dim mode As Integer
Dim corner1(0 To 2) As Double
Dim corner2(0 To 2) As Double
mode = acSelectionSetCrossing
corner1(0) = 28: corner1(1) = 17: corner1(2) = 0
corner2(0) = -3.3: corner2(1) = -3.6: corner2(2) = 0
ssetObj.Select mode, corner1, corner2
' Add all the Circles to the selection set that lie within the crossing of (28,17,0) and
' (-3.3, -3.6,0) by filtering from the current drawing
Dim gpCode(0) As Integer
Dim dataValue(0) As Variant
gpCode(0) = 0
dataValue(0) = "Circle"
Dim groupCode As Variant, dataCode As Variant
groupCode = gpCode
dataCode = dataValue
ssetObj.Select mode, corner1, corner2, groupCode, dataCode
End Sub
