Over 50 Step-by-Step Self Study Program $39 Intuitive, Drill Million Downloads To Date! Based Crash Course Excel and AutoCAD A match made in heaven (again!) by Will on December 8, 2010 Many people are oblivious to the wondrous things that can be achieved with programming. If you cringe at the prospect of writing code, I’ll put this to you now – I cringe at the thought of having to do things manually. Often (and yes, I mean often), I’ll write a little 6 line bit of code that saves me hours of work. Yes, HOURS – perhaps even days. Why people avoid learning this stuff is beyond me, because it really isn’t as hard as it looks. Today I’m going to explain how you can write code in Microsoft Excel VBA that controls AutoCAD. Firstly, let’s get VBA open in Microsoft Excel. With Excel open, press Alt+F11, which should open the VBA IDE (integrated development environment). If this doesn’t work, you can open this by going Tools>Macro>Visual Basic Editor. If you’re using Excel 2007+, you might struggle to find the option. You have to firstly go into Excel Options and check the box to show the Developer Tab on the ribbon interface. So we’re now in a position to write a bit of code. On the left (or perhaps on your right depending on your PC), there should be a section called the Project Explorer. In here you should have a few things called Sheet1, Sheet2, Sheet3 and one called ThisWorkbook. Right click in this area and select Add Module. This will create an area for us to write our code, and if you’re feeling adventurous you can rename the module to whatever you like. Double click the module to edit it. Now let’s see if we can get AutoCAD to do something. If you’ve done any programming before, you will know that you can have variables, and variables can have different types. These types can be simple, or can be more complex things known as objects. AutoCAD has its own type library containing all the object types that we are likely to need. This is very useful to load into our application. To do this, go to Tools>References in the VBA window, and look for an option called AutoCAD 2010 Type Library, or whatever version of AutoCAD you are using. This has now made available some extra types that weren’t available before. howtoautocad.com/excel-and-autocad- -a-match-made-in-heaven-again/ 1/20 3/4/12 Excel and AutoCAD How to link Excel with AutoCAD using VBA Now for some basic code! Put this code into the module, and press the run button at the top of the VBA editor. The subroutine name “Main” is unimportant – we could call this anything we like. S M ( ) D A C A DA A A S A C A D=N A A A C A D . V =T ' O A C A D . A D . U S ' C ' S , . P A C A D A C A D A C A D " H E A A A ! "' P A C A D C A D E Here we’ve created a new instance of AutoCAD, and stored a handle to the AutoCAD object (application) in the ACAD variable, then just printed a line to the AutoCAD command line. Easy right? Ok, but we’re not going to want to open a new instance of AutoCAD every time we want to run some code… So instead, we could use this, which links to an already open instance of AutoCAD: S M ( ) D A C A DA A A ' C A C A D S A C A D=G O ( ," A C A D . A A C A D . A D . U . P " H S A " )' G E ! "' P A A A C A D . A C A D E Great – now we can link to a running instance of AutoCAD. There is one last thing we need to do with this. If we run this code and AutoCAD is not running, we will get an error message. Really, we ought to trap this exception – here’s one way this could be dealt with: S M ( ) D A C A DA A A ' C A C A D O E R N ' T V B A S A C A D=G O ( ," A C A D . A " )' G O E GT 0' T V B A N O T I A C A DI N T ' C S A C A D=N A A ' S A C A D A C A D . V =T ' O , A C A D E I A C A D . A D . U . P " H E S A A A C A D . A A C A D ! "' P A C A D E This code firstly tries to link to an existing instance of AutoCAD. We use the On Error Resume Next statement to skim over any errors that might occur when we try to link to an existing instance of AutoCAD. It is very important that we also add the statement On Error Goto 0 after we’re done ignoring errors. At first glance you might think that it’s a good idea to skim over all errors by adding On Error Resume Next to the beginning of all our code, but this makes it much more difficult for us as developers to debug our application. Use of On Error Resume Next in excess is generally considered bad programming practice, but under controlled circumstances its use is no problem, and it helps trap our error in the example above. After our call to the GetObject function, the ACAD variable either contains a link to our AutoCAD object, or it contains “Nothing” as it was unable to locate one. In the latter case, we are going to create a new instance using the method explained in the first example. Now we’re getting there. Let’s actually do something useful now. Go to Excel – Sheet1, and fill columns A and B with some coordinates, X being in column A, and Y being in column B. Here is some data you can copy/paste if you like, though you may need to copy and paste the columns seperately: 3 7 5 2 3 4 5 6 7 howtoautocad.com/excel-and-autocad- -a-match-made-in-heaven-again/ 8 8 5 3 1.6 1 1 1 1.6 2/20 2 )' P C 2 A C A D . but I’ll leave you to get creative with the that… for now at least. 2010 at 5:38 pm Thanks Will.Cells(Row.

Is there a way I could convert an AutoCAD flow diagram to an Excel diagram made of shapes? That way I can easily change the back ground colour of a shape depending on a variable. So that creates the final calculation: lengthOfArc = (PI * Radius * 2) * (endAngle – startAngle) / 360 Using this we can rearrange the calculation to find out the end angle for a given start angle.ModelSpace.3/4/12 Excel and AutoCAD How to link Excel with AutoCAD using VBA (endAngle – startAngle) / 360 That’s how much of the circumference you need.
