How to manually align an Undet point cloud project to a Revit model when there is no RCP (Recap) file attached or the model coordinates have been changed.

To manually align an Undet point cloud project to a Revit model when there is no RCP (Recap) file attached or the model coordinates have been changed, follow these steps:

Step 1:

Open the Undet project and the Revit model and press preview in slice manager.

Step 2:

Identify distinctive points cloud features that can be easily matched with corresponding elements in the Revit model, such as doorways, windows, or structural components.

Step 3:

In Revit, create reference objects (reference points, reference planes, or reference lines) that align with the points cloud’s identified features.

Step 4:

Make necessary adjustments to position, rotate and move the point cloud to achieve alignment with the Revit model based on the identified features.

Step 5:

Continuously verify the alignment by comparing additional features in the point cloud with the Revit model.

Fine-tune the alignment to ensure an accurate overlay between the two datasets.

Step 6:

Perform similar adjustments for elevation by creating a section view through the building.

Step 7:

Create a forward-facing raster image with a small thickness.

Step 8:

Make necessary adjustments to position. Fine-tune the alignment to ensure an accurate overlay between the two datasets.

Once the manual alignment is complete, you can proceed with further modelling or analysis tasks in Revit.
