Send Large AutoCAD DWG & Revit BIM Files Securely
Architectural blueprints, civil engineering site plans, and multi-discipline 3D BIM models routinely reach 200 MB to 2 GB. Email servers reject them, while public cloud links expose proprietary structural drawings. LimeShare delivers encrypted CAD files with zero data leakage.

Why standard email fails for AutoCAD DWG & DXF
Complex drawings with external XREFs, point clouds, and 3D elevation geometry exceed mail server limits within a single sheet set.
Autodesk Construction Cloud vs LimeShare: Autodesk Cloud requires expensive enterprise licenses and user accounts for outside subcontractors. LimeShare lets you send drawings to any fabricator or surveyor with an instant zero-knowledge link.
Best practices for sending AutoCAD DWG & DXF
- Package your main DWG and external XREF dependencies into a single ZIP file or send as a multi-file batch.
- Protect sensitive building designs and government project specs with an Argon2id password.
- Check 'Burn after first download' when distributing bid tenders to contractors.
Frequently asked questions
Are XREFs and external drawing links preserved?
Yes. Binary files are transmitted untouched. When your recipient opens the drawing in AutoCAD, all internal block references and coordinate systems remain identical.
