The LayoutRuleFixedNumber type exposes the following members.
| Name | Description | |
|---|---|---|
|   |  LayoutRuleFixedNumber | Constructor of LayoutRuleFixedNumber. | 
| Name | Description | |
|---|---|---|
|   |  IsReadOnly |  Identifies if the object is read-only or modifiable.  (Inherited from APIObject )  |  
|   |  NumberOfLines | Get or set the number of the beams in a beam system. | 
| Name | Description | |
|---|---|---|
|   |  Dispose |  Causes the object to release immediately any resources it may be utilizing.  (Inherited from APIObject )  |  
|   |  Equals |  Determines whether the specified object is equal to the current object.  (Inherited from Object )  |
