2. History of Intellicad
created by Boomerang Technology Inc., a privately held developer of Autodesk AutoCAD-compatible software
acquired by Visio in March 1997
late in 1999 Visio set up the IntelliCAD Technology Consortium
there are now several developers shipping commercial versions of IntelliCAD 2000:
Brisnet
CADopia
StrucPlus

3. Why use IntelliCAD? Unrivaled DWG file format compatibility
Affordability
Easy to use
LISP and VBA Development

4. Visual Basic Concepts VB is a Visual programming language
3 steps in constructing a program:
Build the User Interface
Customize the properties of the interface
Attach Program Code
VB is Event Driven.
VB is also an Object-Oriented programming language.

5. VB Project Contents Form Files (.frm)
contain all interface controls and associated VB code
Module Files ( .bas)
store procedures, functions, constant and variable declarations available to every form in the project
MDI Parent Form Files (.frm)
container window that can hold several forms
Class Files (.cls)
objects created in VB

6. Standard VB Controls Label Text Box Command Button List Box
Combo Boxes
Frame
Image Box
Picture Box

7. Visual Basic for Applications (VBA)
programming language which can be found in a number of Microsoft Windows applications
developed by Microsoft as a variation of VB to provide a Windows-compatible programming environment

8. VBA Set Up for Intellicad
Define an Intellicad object.
Establish link between Intellicad and VBA.
Create subroutines which can be loaded from Intellicad.

9. VBA Set Up for Intellicad
Step 1: Define an Intellicad object.
Intellicad object defined is the Intellicad Document.
Global Doc As IntelliCAD.Document
Object is defined in VBA Module File(.bas) so that it can be accessed anywhere in the project

10. VBA Set Up for Intellicad
Step 2: Add VBA object to project.
VBA object (.frm) is added to the project in a manner similar to VB (drag & drop).
UserForm.frm is added to project.

11. VBA Set Up for Intellicad
Step 3: Establish link between Intellicad and VBA.
Bind Intellicad document Doc to drawing file in use (drawParts.DWG) whenever VBA UserForm1.frm is called.
Private Sub UserForm1_Initialize()
Set Doc = drawParts.ThisDocument
End Sub
Intellicad objects such as lines, circles, blocks, layers, etc. can now be added and drawn to the drawing file.

12. VBA Set Up for Intellicad
Step 4: Create subroutines which can be loaded from Intellicad.
Public Sub main()
Load UserForm1
UserForm1.Show
End Sub
This function loads UserForm1.Public functions defined in module files (.bas) can be called from the Intellicad interface.
