Boolean
Boolean operations consist of three types of operations: Union, Intersection, and Cut. The idea of this operation is similar to the concept known from Venn diagrams.
When the cube is "A" and the sphere is "B":
A ⋃ B : objects that belong to A or B ➠ Union
A ⋂ B : objects that belong to A and B ➠ Intersection
A - B : objects that belong to A and not to B ➠ Cut
Before performing boolean operations, you can move and rotate the data using the mouse.
- Click and hold the mouse wheel to move the data around.
- Right-click to rotate the data
Union
Combine two or more meshes into one.
1. Click on the "Union" to open the dialogue window.
2. Select two or more data to combine together.
3. Click "Confirm" to combine the data. Once the data is successfully combined, you will see a new mesh file named "United Mesh" in the Data Tree. Use the Data Tree to easily view and hide data.
Union Example
You can use the "Union" feature to attach support bars to the model. The model below was designed using Medit Model Builder. Import this data from Medit Link, then open in Medit Design. Import the support bar from your PC by clicking "Import Local Files."
Go to Edit Mode and click "Boolean." Arrange the support bars accordingly.
Then, click "Union" to combine the models together. Combine the maxilla data with the support data to create a new, united mesh model. Repeat the same for the mandible.
Click "Complete" to finish and select how you'd like to save your data.
Intersection
Used to extract the intersected mesh data.
1. Click on the "Intersection" icon to open the dialogue window.
2. The "Assign Data" dialogue window will pop up. Assign the data to A and B using the arrows. You can also drag and drop the data to A and B.
- If you have assigned them incorrectly, you can simply swap the data by clicking "Swap A and B."
3. Click "Confirm" and wait for the creation of a new data file. You can see that the intersecting mesh data has been extracted.
Cut
Remove mesh from A that overlaps with B.
1. Click on the "Cut" icon to open the dialogue window.
2. The "Assign Data" dialogue window will pop up. Assign the data to A and B using the arrows. You can also drag and drop the data to A and B.
- If you have assigned them incorrectly, you can simply swap the data by clicking "Swap A and B."
3. Click "Confirm" and wait for the creation of a new data file. You can see the mesh from A that overlaps with B has been removed, removing the occlusion data.
Cut Example
You can use the "Cut" feature to create holes in a custom tray. The model below was designed using Medit Model Builder. Import this data from Medit Link, then open in Medit Design. Import the support bar from your PC by clicking "Import Local Files."
Import cylinder files and duplicate them to suit your needs.
💡 Hints & Tips
You can use the "Detach" function in "Align" to place them evenly. In "Align," place one of the cylinder data in the reference and the rest in the target. Then, select the "Align Target Data Separately" option. When you click the "Detach" button afterward, the target data will be aligned evenly.
Combine the six cylinders to one set using "Union." Duplicate the sets three times to create three sets of six cylinders. Place the cylinder sets are as follows and use the "Cut" function to create holes. Assign the cylinder sets to B so they can be removed from A (A-B).
Click "Confirm" to see the final result.
