Elements that own primitives, such as Equipment and Sub-Structure for example have the following attributes for user input:
|
USRWEIGHT |
Normal Weight. USRWEIGHT is an expression that evaluates to a weight. The value is assumed to be in kilograms unless a unit has been specified. For example: USRWEIGHT (1000g) or USRWEIGHT (RPRO WEIG) |
|
USRWWEIGHT |
Wet Weight for in the case of equipments with fluids. |
|
USRCOG |
An optional position from the element origin for the element Centre of Gravity. If unset then the origin is used. USRCOG is an expression that evaluates to a position with respect to the equipment origin. The values are assumed to be in millimetres unless a different unit has been specified. For example: USRCOG ( E ( 1000 ) S ( 2000 ) D ( 3000 ) ) or USRCOG ( E ( 1m ) S ( 2m ) D ( 3m ) ) |
|
USRWCOG |
An optional position from the element origin for the element Wet Centre of Gravity. If unset then the origin used. |
The above attributes can be queried using a USC--- attribute such as USCWEIGHT to expand any expression for normal weight.
for example USRWEIGHT (RPRO WEIG)
Q USCWEIGHT gives actual result, say 1000
Similar applies for all above attributes.
