![]() From that point forward the number is automatically incremented by one. The first time you run the CALL routine, the starting number is requested. The bubble is created to the left if the second point located is to the left of the first and vice versa. Each callout bubble contains an arrow point (located at the first point requested) and a line to a bubble (the second point requested is the end of the line). Load the LSP file into AutoCAD and type CALL at the command line. The text contains a number that is referenced in a table describing the object or providing a part number reference. Callout bubbles are leaders with circled text. This simple function automates the drawing of callout bubbles in AutoCAD. Heather Randles sent her well-established utility Drawing Callout Figures with Automatic Incrementing Numbers (Tip #2043). NET managed project, so you need to hook into the MGD files.Ĭallouts with Automatic Incrementing Numbers You do not select the AutoCAD 2006 type library in the COM tab! That would create a COM InterOp project similar to VB6-based programming. As was the case last month, you will need to browse to AutoCAD's installed directory and select the managed libraries: ACDBMGD.DLL and ACMGD.DLL (figures 2 and 3). At the start page, I will select Visual C# Projects and a Class Library (figure 1).Next I will add the references to our project just like with Visual Basic 6, VBA or last month's VB.NET project. You can use Microsoft Visual Studio 2002, 2005 or the free beta Microsoft Visual Express C# 2005. To begin, I will open Microsoft Visual Studio 2003. The twist this month is we will use C# instead of VB.NET. The code is derived from the Autodesk sample available within the AutoCAD 2006 install, AutoCAD 2006 ObjectARX toolkit and from the Autodesk website. This way you can compare the screen shots to see how similar both editors are.įor this article, we are going to recreate the classic "Hello World" example and throw the text into AutoCAD's command line and into an MText object just like last month. I will use Microsoft's Visual Studio this month since I used SharpDevelop last month. As with last month's code, you can use any editor to create these commands - including Windows' NotePad - because no graphics are involved. As we go through this process, you may want to reference last month's column. Welcome back! This month we're going to create the same two simple AutoCAD commands that we did last month, but this time in C# (pronounced C-sharp). ![]() The result is a lightweight polyline where the spline used to be. Select the spline objects you want converted, and then specify the number of segments in which to break the object. Just load the LSP file into AutoCAD and type S2P at the command line to activate. By the way, this function set is an excellent example of how Visual LISP and objects open the door for many solutions. Harry wonders what other tips might be lurking around to solve this type of problem. The Spline to Polyline utility solves one of the conversion issues. If you are using additional analysis, design or post-processing software in conjunction with AutoCAD, you may have transferred data that cannot be processed. This conversion facilitates the transfer of continuous spline objects into other applications that do not support that kind of object. ![]() Lloyd Beachy provides Spline to Polyline Conversion (Tip #2039) to change AutoCAD spline objects into lightweight polylines. ![]() The last tip of the month is another specialty tool that not everyone needs, but when you do, it saves a lot of time. ![]()
