Blockit
Manage AutoCAD blocks by creating, updating, renaming, sending, adding attributes, and changing base points.
DV AppCreate and replace numbered block assemblies in AutoCAD while retaining block attribute values.

Assembly provides AutoCAD commands for turning selected objects into blocks and for making a new block from references to an existing one. It assigns names using a progressive numbering pattern and stores the next number in the drawing properties. The replacement command can update selected assembly instances while retaining their attribute values. Additional options cover numbering styles, orientation, base points, labels, object conversion, nested content, layers, solids, and block protection.
AsmCreate turns a selected set of objects into a new AutoCAD block.
The plugin assigns sequential block names and supports Roman numeral or alphabetic numbering.
AsmNew creates a replacement block from references to an existing block.
Values assigned to attributes in the replaced block remain with the corresponding new block.
The plugin can use a largest flat surface, a selected coordinate system, or two points on the X axis for object rotation.
A block base point can come from a lower-left grip, the block center, the bottom center, or the current UCS origin.
The plugin can convert meshes to solids, remove nested blocks and arrays, move objects to layer 0, join solids, add an MText name label, and prevent exploding.
