# SubDCone
## 
SubDCone
The SubDCone command creates a Subdivision cone object.
### Command-line options
#### **DirectionConstraint**
Direction constraints restrict the direction of the cone.
1. **None:** Pick or type a number to set the height.
***
Use [elevator mode](https://docs.mcneel.com/rhino/8/help/en-us/user_interface/accurate_modeling.htm#Elevator_mode), [object snaps](https://docs.mcneel.com/rhino/8/help/en-us/user_interface/object_snaps.htm), or other [modeling aids](https://docs.mcneel.com/rhino/8/help/en-us/options/modeling_aids.htm) to help picking a location.
The cursor location is the positive direction when you type a number to set the height.
***
2. **Vertical**
Creates a cone perpendicular to the construction plane.
***
The CPlane +Z direction is the positive direction when you type a number to set the height.
***
3. **AroundCurve**
Draws the base circle perpendicular to the picked point on a curve. The center line of the cone will be tangent to the curve.
* The curve direction is the positive direction when you type a number to set the height.
#### **Solid (Yes/No)**
Decides if the bottom will be capped to create a solid or open cone.
#### **Radius**
Draws the base circle by picking the center point and a radius point.
[**Diameter**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Diameter) **-** [**Circumference**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Circumference) **-** [**Area**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Area) **-** [**ProjectOsnap**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#ProjectOsnap)
#### **2Point**
Draws the base circle from two opposite points.
#### **3Point**
Draws the base circle through three points.
[**Radius**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Radius)
#### **Tangent**
Draws the base circle tangent to one, two, or three curves.
[**Point**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Point) **-** [**FromFirstPoint**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#FromFirstPoint) **-** [**Radius**](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/commandoptions/circle_sub_options.htm#Radius)
#### **FitPoints**
Draws the base circle by fitting to selected points, control points, or mesh vertices.
1. **VerticalFaces:** Sets the face count between the bottom and the apex.
2. **AroundFaces:** Sets the face count in the east-west direction.
3. **CapFaceStyle (Tri/Quad):** Select to use triangle or quad faces to fill the bottom opening.
***
This option is only visible when AroundFaces is an even number (4, 6, 8...), and Solid=Yes.
Tri is always used when AroundFaces is an odd number.
