Our Draw tool takes a 2D snapshot of your 3D model and enables you to draw on, add text to, and download a copy of the annotated image to your device.

Whether you want to point out a key anatomical structure, explain what is happening in a physiological process, or jot down a few helpful notes for a student, patient, or peer, the Draw tool is perfect for capturing your thoughts on the fly and referencing them later.

Draw tool basics

The Draw tool is available in all 3D models and tours opened in BioDigital's web and mobile apps. It is also enabled by default in all published 3D models but can be disabled in the publishing process.

  2. Click and drag to draw on the image, or switch to the text tool to add notes or labels to the image.
  3. Click the Download button in the upper right to download your drawing to your downloads folder. All images are saved in .png format to preserve image quality.
