Extract Nested Block

Extract Nested Block

Win32 and 64, English

Lee Mac Programming
Convert a nested block into a primary block.

General Usage Instructions

Upon issuing the command syntax ENB at the Autodesk® AutoCAD® command-line, the user is prompted to select a nested block reference to extract from its parent block definition. Following a valid selection, the program will convert all references of the nested block and then proceed to remove the nested block from the primary block definition in which it resides. The program is compatible with uniformly-scaled nested standard blocks, nested dynamic blocks & nested xrefs, nested to any depth, and will process all references of the nested block, even those for which the parent block is also nested within another reference, as the various examples below demonstrate. The program is unfortunately incompatible with blocks nested within dynamic blocks or xrefs, and the program will ignore non-uniformly-scaled block references.
