ReGrid

What it does

Civil 3D can re-project a drawing: pick a new coordinate system from a list and every point is converted. ReGrid brings that to Revit. Pick what the model is in and what it should be in, check the preview, and apply it in one undoable step. The geometry stays where it is; the coordinates the model reports and exports change.

Highlights

• Pick from a list. Hundreds of coordinate systems across Australia, New Zealand, the UK, Europe, North America and world UTM, including MGA and the WA project grids such as PCG2020.
• See it before you apply it. The new base point, shift and rotation, plus a plain verdict on how closely Revit can hold the conversion across your model.
• Check your links. Find out which coordinate system each linked Revit model and CAD file is really in, before a mismatch reaches coordination.
• GIS coordinates on elements. Write each element's easting, northing, elevation and latitude/longitude in another system, for an asset register or COBie.
• Georeferenced IFC. Record the system on the model and set up the Project Information your IFC export needs.
• Whole sets of models. Run it across many files with Batch Tasks. Models already converted are skipped, and anything unexpected is left for you to check.

Before you start

• Know which system the model is in now. ReGrid shows what Revit has recorded and where the base point lands on a map, so you can check.
• Put the project base point on your site datum.
• For workshared models, synchronise first.

Quick start

1. Open Landscape ▸ ReGrid.
2. Pick what the model's coordinates are in now.
3. Pick the new coordinate system and check the preview.
4. Click Apply.
