Using the Anatomy Tree to customize anatomical structures

The Anatomy Tree allows you to perform actions on anatomical structures in your 3D model – such as "painting" or hiding specific structures – by name, as opposed to their physical location in the body.

If you want to perform an action on a structure, you can click on the structure in the 3D model itself. However, if the structure is very small or covered by another structure, it might be difficult or impossible to select it in the 3D model. In that case, or if you simply prefer to navigate anatomical structures by name, you can use the Anatomy Tree to find the structures and then perform actions on them.

There are currently two actions you can perform on an anatomical structure or grouping:

1. Hide or show structures
2. Paint structures

1. Use the Anatomy Tree to hide or show structures

Any anatomical structure or group of structures can be hidden from view in your 3D model.

There are two ways to hide an anatomical structure:

1. Select Hide in the toolbar at the top of the page, and then click on the structure in the 3D model.
2. Hide the structure using the Anatomy Tree.

There are a few ways to hide anatomical structures from the Anatomy Tree, so first you’ll need to decide: How many structures do you want to remove?

• Only one
• More than one
• All but one (i.e., I want to isolate one structure)

1. To hide one anatomical structure:

1. In the Anatomy Tree, locate the individual structure or grouping you want to remove by manually locating it in the tree or by searching for it in the search bar.
2. Hover over the structure or grouping name until two icons appear to the right.
3. To hide the structure or grouping, click on the Hide button .

Want to restore the hidden structure to your model? Click on the Hide button  again.

2. To hide multiple anatomical structures:

1. In the Anatomy Tree, locate each structure or grouping you want to remove by manually locating it in the tree or by searching for it in the search bar.
2. Holding down the SHIFT key, click on the name of each structure or grouping in the list to select it.
3. A drop-down menu that says [#] Objects Selected will appear at the top of the Anatomy Tree. Click on the menu, and hover over Show / Hide.
4. Select Hide Selected.

Want to restore the hidden structures to your model? Repeat steps 1-3 above, hover over Show / Hide, and select Show Selected.

3. To hide all but one anatomical structure (i.e., isolate a single structure):

1. In the Anatomy Tree, locate the individual structure or grouping you want to keep/isolate by manually locating it in the tree or by searching for it in the search bar.
2. Hover over the structure or grouping name until two icons appear to the right.
3. Click More options , hover over Show / Hide, and select Hide Everything Else.

Want to restore the hidden structures to your model? Take these steps:

1. In the Anatomy Tree, locate the individual structure or grouping you isolated above.
2. Hover over the structure or grouping name until two icons appear to the right. 
3. Click More options , hover over Select, and select Select Everything Else.
4. A drop-down menu that says [#] Objects Selected will appear at the top of the Anatomy Tree. Click on the menu, and hover over Show / Hide.
5. Select Show Selected.

2. Use the Anatomy Tree to paint structures

Use Paint to apply colors and visual effects to any anatomical structure or group of structures in your 3D model.

There are two ways to “paint” anatomical structures:

1. Select Paint in the toolbar at the top of the page, select a color or effect in the palette on the right side of the page, and then click on each structure in the 3D model.
2. Select your structures using the Anatomy Tree first, and then apply colors and effects to those selected structures.
