The NoCollisionConstraint prevents collisions between two specific parts, but those parts may still register collisions with the rest of the world. Compared to collision groups, it provides a direct way to disable specific collisions, such as the wheel of a car scraping against the car's body.
The most common way to create this constraint is by selecting No Collision through Studio's Create menu in the Model tab.
|No parts selected||The next two parts that are clicked will be linked together. If the same part is clicked twice, no link will be created.|
|One part selected||The next part that is clicked will be linked to the selected part.|
|Two parts selected||Both selected parts will be linked together.|
