9 times out of 10, your model was exported with a position far from the modeling or BIM platform's origin point. The typical solution is to move the project closer to the origin's axis point, i.e., coordinates (0'-0", 0'-0", 0'-0") and re-export your building geometry with a more accurate reference point. Depending on which BIM platform you have modeled in, the steps to locate the origin point and move the project closer to this point may differ. Before starting the relocation troubleshooting, make sure to first check and see if the Daylight model is floating somewhere near the grid space by searching the Daylight Page. Using a mouse orbit around the 3D space. Also, check the top view and scroll out to see if it is anywhere nearby. If you cannot find the model, then proceed to the section below for your platform. 

Rhino/Grasshopper

You will need to select all your building geometry, then use the command "Move" to relocate your model near the Rhino origin point of 0,0,0 (x,y,z). You can either manually drag the project to Rhino Grid, or type the coordinates: 0,0,0. By placing your geometry here, it will ensure your building will accurately display inside cove.tool.

SketchUp

Moving a model in SketchUp is not as straightforward as the Rhino process. A SketchUp model will more than likely have to be copied over to a new file and be placed at the origin point to export correctly. Only copy over the building geometry that is crucial for the energy and daylight model simulations to the new file, and not landscape+site drawings and geometry. These are the cove.tool layers if you have already created the building layers for cove.tool. The reason you cannot manually move your model closer to the origin point is that the building context records the model space and locks the origin point in place. The locking of the origin point is a particular issue if you have set a geo-location or brought in site/terrain information from a source like GoogleEarth. 

Autodesk Revit

There are 3 different origin points in a Revit project: the Project Base Point, the Survey Point, and the Internal Origin Point. To resolve the display error, first make sure you have the Revit plugin version 2.2.0 release 04/10/2020. This plugin version includes a update that uses the Revit Base Point as the reference point in cove.tool. To have your model display at the center of cove.tool daylight grid, you will need to your Revit base point close to your building project.

PROJECT BASE POINT: This point is used almost exclusively for internal (firm-practice) purposes. It is used to place dimensions relative to the building. It is represented by a blue circle with a cross in the middle. It can also be used to set the angle difference between the True North and the Project North.

First, Locate the Base Point

To see the base point in your revit model, open a site plan and then the visibility graphics window. Expand the Site Category, then make sure the Project Base Point is set to visible.

Next select the project base point in the Revit View, and click on the paperclip icon. A red dash should appear going through the clip icon. Once unclipped, right-click on the project base point and move this element closer to your Revit model. Only the X and Y coordinates should be change, elevation can stay as is.

The project base point should now be located at the exact same spot or near your building in Revit plan view. Repeat the export process and the model should then appear in the center of the Daylight Page.
