**Tube Info:**
* Displays the layer name of current selected tubes.
**S-M-L:**
* Size of the UI. Small, Medium, or Large.
**Refresh Button:**
* Sometimes a layer is deleted or when a new Maya scene is opened, click on this button to refresh the layer list so it can pick up correct layers in current scene.
**Create Tube Layer:**
* Select curve(s), and click on this button to create a new tube layer.
**Separate Layers:**
* When this is turned on, a layer will be created for each selected curve.
**Extract Selected Layers:**
* Makes a duplicate of proxy tubes from selected tube layers.
**Extract All Layers:**
* Makes a duplicate of proxy tubes from all tube layers.
**Remove All Layers:**
* Delete all layers and the setup.
***
### **Layer Name Left/Right Click**
**Left Click:**
* ****selects the tubes in the layer
**Right Click:**
* ****shows menu for add/remove tubes, copy/paste tubes from one layer to another, or rename this layer.
**Ctrl + Click or Shift + Click:**
* **** select multiple layers
***
### Layer Buttons
**Color Swatches:**
* Change the color of tubes by clicking on the color swatch.
**Layer visibility (V):**
* Like Maya Display Layers, turn on/off tubes in that layer. When multiple layers are selected, all will be toggled
**Layer Lock (L):**
* Like Maya Display Layers, set template/lock on tubes in that layer to keep them from being selected. When multiple layers are selected, all will be toggled
**Editor (E):**
* Opens up the UI for tube controls.
**Add Selected Curves (+):**
* Add selected curves into this layer. The tool will apply the global settings. When multiple layers are selected, curves will ONLY be added to the layer that was clicked on.
**Remove Selected Tubes (-):**
* Select geometries in the viewport, and click on - to remove them from the layer.
**Delete Layer (x):**
* ****Delete entire layer.
***
### Layer Utilities
The tool comes with Visibility, Lock and Up/Down buttons:\
1. Toggle all layer **Visibility ON**\
2\. Toggle all layer **Visibility OFF**\
3\. **Invert** current layers **Visibility** states\
4\. Toggle all layer **Lock ON**\
5\. Toggle all layer **Lock OFF**\
6\. **Invert** current layers **Lock** States\
7\. Move selected Layer(s) Up\
8\. Move selected Layer(s) Down \
9\. Move selected Layer(s) to the top\
10\. Move selected Layer(s) to the bottom
***
## Tube Control UI
**Select Tubes:**
* Click on this button on the very top of the UI to quickly select all tubes in this layer.
**Template On Curve Toggle:**
* When this is turn on, curve toggling will also set template to the geometry. Sometimes this allows easier viewing of the geometry while moving CV's of curves.
**Toggle Tube Curve(s):**
* Display the underlying curve that is controlling the tubes. You can toggle the curves and use the interactive tools for more adjustment to the tubes.
**Re-Cal Curve:**
* After manipulating curve CVs, if the length of the curve has changed, click on this button to re-length geometries to the length of curves.
**Root Extend:**
* Sometimes the underlying head/body geo have curvatures, this allows the proxy tubes to ‘go into’ the head/body geo so there are no ‘gaps’.
### Global Tab
**Length SubD:**
* Controls the length subdivision of all tubes in the current layer.
**Width SubD:**
* Controls the width subdivision of all tubes in the current layer.
**Scale:**
* Controls the size of all tubes in the current layer.
**Scale X:**
* Controls the scaling in the X-axis of all tubes in the current layer.
**Scale Z:**
* Controls the scaling in the Z-axis of all tubes in the current layer.
**Rotation:**
* Rotates all tubes in layer in degrees.
**Twist:**
* Twists tubes around the central axis. This setting needs to be coupled with the twist ramp.
### Target Tab
* This tab displays the settings for **individual selected tubes**. If you change any settings in this tab, the corresponding setting in the global tap will be **locked.**
* You can unlock the **global** settings by '**middle mouse clicking**' on the greyed out text. Just be careful that by unlocking global settings, it will apply the value for that setting to all the tubes in this layer.
