Hi All
It has been a while since the last time I posted... but it feels good to be back.
In this post, I will show you how to insert some objects into the CAD model space.
HOW TO INSERT A CIRCLE
In order to insert an object you will need to declare the object and its parameters, in the case of a circle you will need a radius and a center point.
STEP 1. declaring the object and parameters
Dim circleObj As AcadCircle
Dim radius As Double
Dim centerpoint(0 To 2) As Double
STEP 2. Setting the values for the radios and the center point
radius = 500#
centerpoint(0) = 0#: centerpoint(1) = 0#: centerpoint(2) = 0#
STEP 3. Finally sending the command
Set circleObj = AcadFile.ModelSpace.AddCircle(centerpoint, radius)
*AcadFile must have been previously declared and assigned, I show how to do it on my post AE1. HOW TO LAUNCH AUTOCAD FROM EXCEL. https://discoverthevalueof.wixsite.com/blog/post/ae1-how-to-launch-autocad-from-excel
HOW TO INSERT A LINE
To insert a line you will only need to define 2 points.
Dim LineObj As AcadLine
Point1(0) = 1000#: Point1(1) = -500#: Point1(2) = 0#
Point2(0) = 2000#: Point2(1) = 500#: Point2(2) = 0#
Set LineObj = AcadFile.ModelSpace.AddLine(Point1, Point2)
HOW TO INSERT A TEXT
the command to insert a text will ask you for the CAPTION to display, the point where you want to place the text and the size of the text.
Dim textObj As AcadText
Point1(0) = 2500#: Point1(1) = 0#: Point1(2) = 0#
Set textObj = AcadFile.ModelSpace.AddText("SAMPLE", Point1, 150)
This is a very simplified version of how to do it, there are ways to select the text style, and also you could refer the caption to a variable.
HOW TO INSERT A DIMENSION
As in any CAD software, there are 2 different types of dimension, we have rotated dimensions. and aligned dimensions.
For both objects, you will need to assign 3 points and for the case of the rotated dimension, you will also need the angle to rotate the object. You must be aware VBA reads angles as radians' value.
So here we go...
DimRotated
Dim Dimension(0 To 0) As Object
Point1(0) = 4000#: Point1(1) = -500#: Point1(2) = 0#
Point2(0) = 5000#: Point2(1) = -500#: Point1(2) = 0#
Point3(0) = 4000#: Point3(1) = -1500#: Point3(2) = 0#
Set Dimension(0) = AcadFile.ModelSpace.AddDimRotated(Point1, Point2, Point3, 0)
DimAligned
Point1(0) = 4000#: Point1(1) = 500#: Point1(2) = 0#
Point2(0) = 5000#: Point2(1) = -500#: Point1(2) = 0#
Point3(0) = 5000#: Point3(1) = 1500#: Point3(2) = 0#
Application.Wait (Now + TimeValue("0:00:01"))
Set Dimension(0) = AcadFile.ModelSpace.AddDimAligned(Point1, Point2, Point3)
SAMPLE CODE:
The following is a copy of the code that i used to make the video for this post.
Sub AUTOCAD_COMMANDS_FROM_VBA()
Dim ACAD As AcadApplication
Dim Point1(0 To 2) As Double
Dim Point2(0 To 2) As Double
Dim Point3(0 To 2) As Double
'***** OPENING AUTOCAD EXISTING DRAWING ****
On Error Resume Next
Set ACAD = GetObject(, "ACAD.Application")
If (Err <> 0) Then
Err.Clear
Set ACAD = CreateObject("autocad.Application")
If (Err <> 0) Then
MsgBox "Could Not Load AutoCAD!", vbExclamation
End
End If
End If
ACAD.Visible = True 'If you want to see AutoCAD on screen
dwgName = "C:\Users\User\Desktop\SAMPLEAE2"
bReadOnly = True
Set AcadFile = ACAD.Documents.Open(dwgName, bReadOnly)
If AcadFile.ActiveSpace = acModelSpace Then
End If
'***** INSERTING A CIRCLE *****
Dim circleObj As AcadCircle
Dim radius As Double
radius = 500#
Point1(0) = 0#: Point1(1) = 0#: Point1(2) = 0#
Set circleObj = AcadFile.ModelSpace.AddCircle(Point1, radius)
'***** INSERTING A LINE *****
Dim LineObj As AcadLine
Point1(0) = 1000#: Point1(1) = -500#: Point1(2) = 0#
Point2(0) = 2000#: Point2(1) = 500#: Point2(2) = 0#
Set LineObj = AcadFile.ModelSpace.AddLine(Point1, Point2)
'***** INSERTING A TEXT *****
Dim textObj As AcadText
Point1(0) = 2500#: Point1(1) = 0#: Point1(2) = 0#
Set textObj = AcadFile.ModelSpace.AddText("SAMPLE", Point1, 150)
'***** INSERTING A DIMENSION *****
Dim Dimension(0 To 0) As Object
Point1(0) = 4000#: Point1(1) = -500#: Point1(2) = 0#
Point2(0) = 5000#: Point2(1) = -500#: Point1(2) = 0#
Point3(0) = 4000#: Point3(1) = -1500#: Point3(2) = 0#
Set Dimension(0) = AcadFile.ModelSpace.AddDimRotated(Point1, Point2, Point3, 0)
Point1(0) = 4000#: Point1(1) = 500#: Point1(2) = 0#
Point2(0) = 5000#: Point2(1) = -500#: Point1(2) = 0#
Point3(0) = 5000#: Point3(1) = 1500#: Point3(2) = 0#
Set Dimension(0) = AcadFile.ModelSpace.AddDimAligned(Point1, Point2, Point3)
End Sub
As always, I hope that this post is helpful and that you enjoyed it.
I will read you on the comments.
Until next time!
