CAD Block Remapper
Automatically place Revit Family Instances based on their CAD Block locations, and automatically host them to the nearest ceiling/wall for hosted families.
CAD Block Remapper is a FREE app by Bird Tools, that is both an AutoCAD and a Revit add-in: It allows the user to map families to linked CAD Blocks, and would place the family instances on their correct locations.
No CAD import, nor Import Explosion are involved in the process, only CAD linking, as the CAD files are automatically processed by the AutoCAD add-in part of the app.
It supports both hosted and non hosted families, and can host families on both the nearest ceiling and the nearest wall, with an option to specify vertical offsets. The tool also automatically detects the CAD Block rotation angles and places the new family instances accordingly.
Autodesk Revit and Autodesk AutoCAD 2019-2020-2021-2022-2023-2024 editions are all supported.
