With kitchens and baths in mind, most designers start with creating a more traditional 2D moodboard (like this: http://prntscr.com/mrj519) on DesignFiles to help their clients get an idea of the overall look and feel of the space.
We recommend also uploading a to-scale 3D technical drawing to the project to help your clients clearly see the final layout.
You can use any program you like (ex: https://www.sketchup.com/) to create the final renderings. Just make sure you save your renderings as a jpg, png or gif and you will be able to upload the rendering to your DesignFiles account and include it in your client presentation.
This will ensure the installation teams will have all of the proper dimensions and details they need when putting the room together.
