Every AutoCAD database ( Database ) contains a collection called the BlockTable . Think of the BlockTable as a dictionary where the keys are the names of the blocks, and the values are the BlockTableRecord objects. The drawing itself is structured as special types of block table records, such as Model Space ( *Model_Space ) and Paper Space ( *Paper_Space ). Block Definition ( BlockTableRecord ) Create the BlockReference // args: Insertion Point, ObjectId
By mastering these core mechanics of the AutoCAD .NET API, you can control drawing elements with precision, building fast, robust, and highly scalable CAD plugins. If you want to tailor this further, tell me: What specific are you targeting?
Open objects as OpenMode.ForRead unless you intend to modify them ( OpenMode.ForWrite ). Minimizing objects opened for writing optimizes database execution speed.
Create a simple block named "MySquare" consisting of a square polyline.
