Create a palette in the Palette Builder and then open this for editing to add plants (or mixes) from the libraries.
Planting mixes are created and managed using the Planting Mixes tools and must be added to a palette before they become available for use in CS ArtisanRV planting workflows. Mixes can be created from scratch, or by selecting existing plants from a palette and copying them to a Mix Library where percentages and specification details can be defined.
Once a mix has been created, it should be added to the appropriate project palette and downloaded to your local machine. The mix can then be selected and used in the same way as any other plant or palette item when placing detailed planting in a Revit model.
Mixes are created via the Planting Mixes tooland then are added to palettes the same way as for single plants.
You can also create a new Planting Mix by adding records from a palette to the Mix Libraries.

You will be prompted to select a Mix Class to add the selection and to create a name for the New Mix.

You can then open the newly created mix in the Mix Libraries (Library – Planting Mixes - <Mix Class>) and add percentages as required.
After creating the mix/es, add these to project palette/s as required.
If the plant species you require is not available in the standard libraries, you can create your own record using the Custom Plants tool. This allows landscape professionals to add project-specific plants, cultivars, or other planting content to the CloudScapes libraries, ensuring that required species can be incorporated into palettes, planting mixes, schedules, and Revit models.
Once created, custom plants can be managed in the same way as standard library content and can be added to palettes for use in detailed planting designs.
Use the Custom Plants toolto add plants to the libraries.
Use the Download Palettes tool to save a local copy of palettes created in the palette builder. Note that you may need to re-download a palette if it has been edited and you want to access the updated information.
After editing a palette in the Palette Builder, you will have to rerun the Download Palette tool to ensure that new planting placed in the model is from the modified palette. Note that re-downloading a palette will have no effect on planting already placed in the model. To update planting already placed in the model, use the various editing options (Revit properties, Edit Planting, Substitute Planting, Planting Browser).
There is no direct association between palettes (including mixes) and Revit models. You are able to select anything you wish from the downloaded palettes but then you are able to use the various editing options (Revit properties, Edit Planting, Substitute Planting, Planting Browser) to change any component placed in the model.
