Online DWG Layer Splitter & Batch Drawing Separator
Direct navigation to objective in-depth evaluation and anti-audit.
Why Do You Need Professional Evaluation?
Processing is extremely large and includes architectural, mechanical and electrical, In order to distribute the drawings of different disciplines to different contractors when creating a general drawing with dozens of layers such as pipelines, It needs to be manually split into independent single layer sub-DWGs. Cloud DWG Layer Splitter Can identify layer tables in batches and automatically separate them in the backend (WBLOCK Figure), and keep the datum origin completely coincident.

Enterprise Security & Anti-Piracy Compliance Warning
The general map represents the overall geographical arrangement and all confidentiality of the project. Uploading the general map to a public cloud service provider is very easy to encounter global leaks and compliance audits.. Please first load a minimalist file in local AutoCAD AutoLISP Scripts are used to split local layers, and direct unpacking and processing on the public network are prohibited..

Enterprise Data Conversion Best Practices Guide
Perform local PURE purification
Run PURGE before splitting to clean up unreferenced empty layers, This prevents the split sub-drawings from still containing a bunch of meaningless empty layer lists.
Absolutely preserve coordinate system consistency
When writing out a new tile (WBLOCK), Be sure to use absolute zero (0,0,0) as the base point, Otherwise, each sub-drawing will be XREF (external reference) When they overlap, they will completely drift out of position.
Off-network stand-alone LISP script deployment
The processing of the enterprise's sensitive general picture requires the use of AutoLISP or in a completely disconnected environment. Python Offline script splits output with one click.
Technical FAQ
Q: Why are the split sub-drawing files still the same size as the original drawing? ▼
This means that most of the elements in the original image may be contained in external references (Xrefs), Or the drawing contains a large number of uncleaned registry junk entities (Regapps). It is necessary to bind external references first and thoroughly purge Split after purification.
Q: How to quickly split a layer locally using a LISP script? ▼
This code can be loaded: `(foreach lay (layoutlist) (command "-WBLOCK" (strcat lay ".dwg") "" ...))` It can write it out as a local file in seconds according to the layout layer and layer table.
