Join Josh Modglin for an in-depth discussion in this video Understanding ObjectIds, part of AutoCAD Add-ins Using VB.NET.
- [Instructor] Having the database object…and being able to access that…begins our quest to start working with the objects…within our drawing.…Now we're not just talking about lines and circles,…but we're also talking about the non-graphic objects,…such as layers and textiles.…All of this though goes back to working within the database…and understanding what Object IDs are.…So let's go ahead and we're going to open up our exercise.…
We're going to go to the Exercise folder,…Chapter five, 05-02,…and go inside the 05-02 solution.…When we do there is that Initialization class,…we're going to open that up.…And there's a command already started…for us named LIDBObjectId.…Now what is an Object ID?…Well when you initialize…or open up a new drawing or document,…every single object,…again, non-graphical like layers or graphical,…are assigned a unique pointer,…a unique ID.…
And that unique ID is what's referred to as an Object ID.…When you close that drawing,…all of those are lost…and it restarts the next time you open up the drawing.…
