AutoCAD .NET Addin Wizard (AcadNetAddinWizard) is far more than just some templates scattered around. It is a real-wizard-sense wizard, i.e. multi paged, configurable, flexible and intelligent. It also includes various project item wizards, coders, and widgets for AutoCAD .NET programming.In this article, let us see how the Entity Jigger wizard of AutoCAD .NET Addin Wizard (AcadNetAddinWizard) can create a xline jigger automatically in no time for us.The Entity Jigger wizard can be found from the Add New Item UI of both Visual C# and VB.NET of Visual Studio both full-fledged and Express in version both 2008 and 2010. Let’s take the C# of Visual Studio 2010 for an example. The AutoCAD Addin category will appear under the Visual C# Items node of the Installed Templates and its various item wizards including the Entity Jigger wizard appear in turn in the middle pane:http://spiderinnet1.typepad.com/.a/6a0153928ee38e970b016764b4a008970b-800wiHere are wizard pages and some sample fill-outs of the Entity Jigger wizard for the coming Xline Jig:

}</div>The only code change needs to be made manually is to check if the second point equals to the base point and do nothing if true. Apart from this tiny point, the auto-generated code works well, including taking care of user cancelations and honoring the current UCS. The following demonstrates how it behaves in AutoCAD.http://spiderinnet1.typepad.com/.a/6a0153928ee38e970b0168e9b5aae8970c-800wi
The Entity Jigger wizard of the leading edge AutoCAD .NET Addin Wizard (AcadNetAddinWizard)can help you create EntityJig derivatives for various entity types automatically, quickly, reliably and professionally.
