In this tutorial, we will show you how to use Plex-Earth and PVcase for importing georeferenced, aerial and satellite, historical and up-to-date imagery as well as creating 3D terrain-based PV layouts.
PVcase, which is a plugin for Autodesk (AutoCAD), is a powerful solar engineering software built for utility-scale power plant designs. Combined with Plex-Earth’s terrain features you can create advanced 3D modeling for photovoltaic projects quickly and easily. This helps you to visualize complex arrangements in the real world, then makes it much easier to communicate your ideas and concepts to the project’s stakeholders.
The following steps below will guide you on this procedure:
Step 1. Georeference your drawing
Step 2. Import an Imagery Mosaic
Additional Step. Import up-to-date & historical satellite imagery with Timeviews
Step 3. Import a Plex-Earth Terrain
Additional Step. Order drone data in CAD!
Step 4. Insert an AutoCAD object for the dynamic terrain
Step 1. Define the Frame & Park settings and the Layout generation settings
Step 2. Defining generation boundaries and generating the frames
Recommended Step. Export your project to Google Earth
Starting in Plex-Earth
Step 1. Georeference your drawing
Before proceeding with any Plex-Earth feature, you will need to georeference your drawing. You can do so, by choosing one of the two available options provided. If your drawing is already georeferenced via AutoCAD’s GEO command, Plex-Earth automatically recognizes this so you can skip this step.
Step 2. Import an Imagery Mosaic
To Import an Imagery Mosaic, go to the respective button located in the Imagery panel of the Plex-Earth's ribbon, specify the preferred Imagery Provider & Image Quality, specify the Imagery cover area, and capture the images. For more details feel free to check out this step-by-step tutorial, by clicking here.
Additional Step. Import up-to-date & historical satellite imagery with Timeviews
Google images are sufficient in terms of quality, but sometimes they can be significantly outdated.
In our case, if we check the historical imagery of Google Earth in Caberra, Australia, we will find out that the date of image we imported goes back to 2020.
Plex-Earth, has found a way to overcome this obstacle, with its feature, Timeviews, which brings a wide variety of up-to-date and historical images from Airbus and Maxar in CAD.
The PVcase article was updated on the 16th of January 2023.
Step 3. Import a Plex-Earth Terrain
You can now proceed in importing a terrain for your area of interest. With Plex-Earth you can select the terrain data of your choice, choosing among its providers, Google Eleveations, AWS and Cesium. Click here to see how to import terrain.
This part is considered extremely essential, as you will need our Plex-Earth's Terrain in order to be able to place your Solar Panels on the correct coordinates and successfully export them to the real-life environment of Google Earth, afterward.
Step 4. Insert an AutoCAD object for the dynamic terrain
In order to use the terrain imported in PVcase, you will need to insert a AutoCAD object format that is accepted by PVcase.
You can find more information on the type of terrain/topography data that is compatible with PVcase here. We suggest inserting points or contour polylines for easier use.
To insert the object, click on the Insert button in the Terrain Editor and select your preferred object.
Your terrain is now ready to be used by PVcase.
Additional Step. Order drone data in CAD!
In cases where higher accuracy is needed, Plex-Earth is proud to be offering drone deliverables (orthomosaics, point clouds, 3D models) directly into CAD, from almost anywhere in the world, through its collaboration with the drone surveying solution company, Inflights.

Proceeding with PVcase
Step 1. Define the Frame & Park settings and the Layout generation settings
Go to the Add-ins tab of AutoCAD and start PVcase.
Before generating frames onto the terrain, the Frame & Park settings, as well as the Layout generation settings, must be fully defined.
Set up the necessary parameters for the Frame creation, Placement setup, and Park settings by clicking on the Frame & Park settings button.
Access the Layout settings and Topography settings by clicking on the Layout generation setting button.
Define the suitable parameters for each setting.
Under the Topography settings, you will have the option to select the terrain object inserted earlier using Plex-Earth. Click on the Select button then select the terrain object.
With that, PVcase now recognizes the terrain and you are now ready to generate the frames on an area.
You can find several tutorials on PVcase’s support page for a more comprehensive guide on designing your solar plants here.
Step 2. Defining generation boundaries and generating the frames
Once the parameters are all set, you can now generate your frames on selected PV areas.
To proceed, make sure that you have an existing closed polyline that you will select as the generation boundary. Take note that this region or boundary is separate from the actual site boundary and is offset from it. You can also select exclusion zones if needed.
Once the parameters are all set, the generation can be done by selecting one out of two-generation types: Generate single area or Generate multiple areas.
Once the generation is complete, you can go ahead and apply all the preferred parameters and settings for your solar farm project with PVcase.
You can see more information about creating several PV layouts in PVcase’s Help Center.
If you have any questions or concerns related to PVcase, please contact their support team.
Export your project to Google Earth (Recommended)
This final step is totally optional, but we highly recommend it if you want to visualize your project in a real-life environment through Google Earth. The Export KML/KMZ (for 2D and simple 3D projects) and Export 3D KMZ (for 3D projects with textures and materials) features of Plex-Earth will help you elevate your presentation, as well as the outcome it will have on your audience.
