Convert DWG to RVT

Revit users need an RVT project when they must edit a building model, produce coordinated views and schedules, or submit a Revit-native deliverable. A DWG can be linked or embedded in an RVT as CAD reference data, but its lines and solids do not automatically become Revit BIM elements.

What DWG contains

DWG is Autodesk AutoCAD’s native drawing format. It can store 2D objects such as lines, polylines, text, dimensions, hatches, blocks, and layers, plus 3D solids, surfaces, meshes, and external references (Xrefs).

Architects, engineers, surveyors, fabricators, and CAD drafters use DWG files for plans, site surveys, structural details, MEP backgrounds, and manufacturing drawings. AutoCAD, AutoCAD LT, Civil 3D, BricsCAD, DraftSight, and many discipline-specific CAD applications can create or edit DWG files.

What RVT contains

RVT is Autodesk Revit’s native project format. It stores BIM data including levels, grids, walls, floors, roofs, doors, windows, families, materials, views, sheets, schedules, phasing, worksets, and relationships between elements.

A native Revit wall has a type, height, material layers, level constraints, and hosted openings; a DWG line representing that wall has none of this data. This model intelligence allows coordinated plans, sections, elevations, quantities, room data, and schedules to update from the same project model.

How to create an RVT from a DWG

Autodesk Revit is the appropriate desktop application. There is no dependable automated conversion that turns a typical DWG drawing into editable Revit walls, doors, floors, and families. The practical workflow is to link the DWG as an underlay and model native Revit elements over it.

1. Open the source file in AutoCAD or a compatible CAD application. Delete irrelevant annotation, hatches, duplicate geometry, and unused blocks or layers. Run AUDIT to repair drawing errors and PURGE to remove unused definitions.
2. Check source units with UNITS. Confirm whether the drawing was created in millimetres, metres, feet, or inches before placing it in Revit.
3. Resolve Xrefs. Keep the referenced files in their expected relative locations, or use AutoCAD’s Insert → Bind command when one self-contained DWG is required. Binding can increase file size and alter layer names.
4. Open the destination Revit project and create the required levels and grids. Set project display units through Manage → Project Units if required, but select the actual DWG units in the CAD linking dialog.
5. For a drawing likely to change, select Insert → Link CAD. Choose the DWG, specify the correct import units, and use Auto - Origin to Origin only when the CAD and Revit origins are known to match. For coordinated site files, use shared coordinates only after the coordinate system has been verified.
6. For a 2D plan underlay, use Current view only where appropriate. Control visibility by CAD layer in Visibility/Graphics rather than deleting useful source layers.
7. Use Insert → Import CAD only when the DWG must be embedded in the RVT and will not need updating. An imported DWG increases RVT size; a linked DWG remains an external dependency and must accompany the RVT when it is delivered.
8. Trace or rebuild the design with native tools such as Architecture → Wall, Door, Window, Floor, and Roof. Revit’s Pick Lines option can speed up wall and floor boundary creation from clean CAD linework, but verify dimensions, levels, wall types, and openings.
9. Hide or unload the DWG after it is no longer needed, then save the project through File → Save As → Project as project.rvt.

3D DWG files and online services

A 3D DWG can be linked or imported for reference, but its solids, surfaces, meshes, blocks, and proxy objects normally remain non-native CAD geometry. They do not gain Revit parameters, hosts, schedules, or system-element behavior. Rebuild important geometry as Revit elements or create appropriate Revit families when editable BIM content is required.

Do not rely on websites claiming automatic DWG-to-RVT conversion for a production model. Autodesk does not provide a browser-based service that converts arbitrary DWG geometry into a native Revit BIM project. Autodesk Viewer is suitable for inspecting DWG files online, but it cannot create RVT files. Outsourced BIM modeling can be appropriate for large drawing sets, but it is a manual modeling service; require a sample deliverable, stated Revit release, scope, and level of development.

Compatibility and quality limits

Linking or importing a DWG is not BIM conversion. CAD layers, linework, and blocks do not become Revit categories, room boundaries, wall assemblies, or schedule data without modeling and data assignment.

Do not explode imported CAD unless there is a specific, limited need. Exploding can create thousands of separate Revit lines, degrade performance, and produce difficult-to-manage geometry. Large meshes, deeply nested blocks, custom AutoCAD objects, and proxy objects can also display incorrectly or slow Revit.

For survey and civil drawings, establish the project base point, survey point, and shared-coordinate method before modeling. Repositioning a CAD link after native elements have been traced from it can misalign the model.

Revit projects upgrade to newer releases when opened, but a project saved in a newer Revit release cannot normally be opened in an older one. Confirm the recipient’s required Revit version before delivery, and package linked DWGs with the RVT when the links must remain available.
