NOTE: Although the primary curves and the cross curves are not exactly
perpendicular, They should form a roughly rectangular network.Overview | Statement List | Example 1 | Example 2

Creates a free form body using the Curve Mesh method. You must specify a series of primary and cross curves through which to calculate the body. You must specify at least two primary and two cross curves.
The primary and cross curves must either share end points or intersect.
If you would like to use a point as one of the cross curves, then you should use the BSURF command.
The current U and V surface display parameters are applied to each patch formed between two crossing curves in the body.

Description |
|
PRIMA |
Minor word that indicates that the following object list consists of curves in the primary "U" direction. |
|
obj list1 |
A list of existing curves in the primary direction. |
|
CROSS |
Minor word that indicates that the following object list consists of curves in the cross "V" direction. |
|
obj list2 |
A list of existing curves in the cross direction. |
NOTE: Although the primary curves and the cross curves are not exactly
perpendicular, They should form a roughly rectangular network.
Both sets of curves must be specified in order, moving from one side of the body to the other.
The total number of primary and cross curves must not exceed 102.
The primary and cross curves may be specified using an array. You can use a sub-range operator containing variables. For example the range of splines SPL(1..10) is valid, as is the range SPL(1..K).
