  1. Practical Examples of Customizing AutoCAD Entity Behavior Stephen Preston Autodesk Developer Network

  2. Class Objective To give you ideas • Useful applications for Overrules • What Overrules can do • A few tips and tricks It will not • Teach you how to program in .NET • Teach you how to create ObjectARX Custom Entities • Provide complete of coverage of all API functions All the code shown will be in VB.NET • API concepts are common to all .NET languages

  3. About the Presenter Stephen Preston Americas Manager Developer Technical Services Autodesk, Inc.

  4. Agenda • What is an Overrule? • Demos • My First Overrule • DrawingStuff revisited • DimensionPatrol • CustomLeader • DigSigStamp • Network • Call to action

  5. Getting started with Overrules

  6. What is an Overrule?

  7. Choose your weapons • We have nine overrule classes to play with • ObjectOverrule • PropertiesOverrule • DrawableOverrule • OsnapOverrule • TransformOverrule • GripOverrule • SubentityOverrule • HighlightOverrule • GeometryOverrule

  8. Demo – My First Overrule

  9. Drawing stuff • Most common use of Overrules • Three ways to draw custom graphics in your overrule • GraphicsInterface primitives • Embedded entities (Geometry.Draw) • Embedded entities (WorldDraw) • Using embedded entities is very similar to adding an entity to the drawing • Simpler than GraphicsInterface primitives • Less flexible

  10. Demo – Drawing Stuff • Three ways to draw your graphics

  11. Demo - DimensionPatrol • Custom filters

  12. Demo – CustomLeader • Xdata and jigging

  13. Demo - DigSigStamp • Customizing BlockReferences

  14. Demo - Network • Inter-object relationships

  15. Call to action You’ve see what Overrules can do Now go and use them in your own applications

  16. Learning more • See handout
