A wire is a constant radius 3D path made up of straight line sections. It is defined using the WIRE keyword, followed by the wire radius and an optional parameter defining the number of chords to use for the crossection.

   WIRE <radius> [<sides>]

Example

    WIRE 12.5 10

The WIRE keyword is immediately followed by a 3D polyline that defines the vertices of its centerline.

A 3D polyline is described by the number of 3D points it possesses, followed by the coordinate data on one or more new lines.

    3DPL <n_points>
    <x1> <y1> <z1> ... <xn> <yn> <zn>

Example

    3DPL 5
    0.0 0.0 0.0
    0.0 0.0 250.0
    300.0 0.0 250.0 
    650.0 0.0 250.0
    2300.0 0.0 0.0

A sphere is defined using the keyword SPHE along with a center point, radius and rendering accuracy. In the case of the sphere, this represents the number of edges from pole to pole:

   SPHE <x> <y> <z> <radius> [<sides>]

Example

   SPHE 125.0 2035.0 -50.0 375.0 32

A barrel is used as a more precise way to model a solder ball that has been reflowed; during the reflow process the ball partially melts and squashes down. The parameters used are consistent with Optimal's model parameters.

BARL <x> <y> <z> <radius> <r_upper> <r_lower>  [<sides>]

Example

   BARL 125.0 2035.0 -50.0 375.0  275.0 275.0  12
