/* Equacion Espiral

Use a cartesian coordinate system

Utilizar la herramienta "curve"

radius = 10increment = 10nrofturns = 10

x = ( radius + increment * t * nrofturns ) * cos ( t * nrofturns * 360 )y = ( radius + increment * t * nrofturns ) * sin ( t * nrofturns * 360 )

/* Comparison Operators

Comparison operators are used when a TRUE/FALSE value can be returned. For example, the following relation returns TRUE whenever d1 is greater than or equal to3.5. It returns FALSE whenever d1 is less than 3.5:

d1 >= 3.5

The following comparison operators are supported:

== Equal to

> Greater than

>= Greater than or equal to

!=, <>,~= Not equal to

< Less than

<= Less than or equal to

| Or

& And

~, ! Not

Note: The "equal to" assignment operator is different from the "equal to" comparison operator.

The operators |, &, !, and ~ extend the use of comparison relations by enablingseveral conditions to be set in a single statement. For example, the following relation returns TRUE whenever d1 is between 2 and 3, but not equal to 2.5:

d1 > 2 & d1 < 3 & d1 ~= 2.5

/* The following operators can be used in relations, both in equations and in conditional statements./* Relations can include the following mathematical functions:

cos () cosine

tan () tangent

sin () sine

sqrt () square root

asin () arc sine

acos () arc cosine

atan () arc tangent

sinh () hyperbolic sine

cosh () hyperbolic cosine

tanh () hyperbolic tangent

Note: All trigonometric functions use degrees.

log() base 10 logarithm

ln() natural logarithm

exp() e to an exponential degree

abs() absolute value

ceil() the smallest integer not less than the real value

floor() the largest integer not greater than the real value

/* Graph Evaluation Function

Graph evaluation function enables you to use graph features to drive dimensionsthrough relations. The dimensions can be section, part, or assembly dimensions.The format is the following:

evalgraph("graph_name", x)

where:

graph_namethe name of a graph.

xthe value along the x-axis of the graph for which the y value is returned.

For sweep features, you can specify the trajectory parameter trajpar as the second argument of this function.

Note: A graph feature is usually evaluated for its defined x-axis values. When it is evaluated beyond the defined range, the y-axis values are extrapolated. The system calculates the extrapolated value for values of x less than the initialvalue by extending a tangent line back from the initial point. Likewise, the system calculates the extrapolated value for values of x greater than the final value by extending a tangent line out from the final point.

Composite Curve Trajectory Function

The trajectory parameter of a composite curve, trajpar_of_pnt, can be used in relations.

The following function returns a value between 0.0 and 1.0:

trajpar_of_pnt("trajname", "pointname")

where:

trajnamethe name of a composite curve.

pointnamethe name of a datum point.

The trajectory is a parameter along the composite curve at which the plane, normal to the tangent of the curve, passes through the datum point. The datum pointdoes not have to be located on the curvethe parameter is calculated at the pointon the curve that is closest to the datum point.

If the composite curve is used as the spine of a multitrajectory sweep, then trajpar_of_pnt either agrees with the parameter trajpar at this plane, or else with 1.0 trajpar (depending on your choice of the starting point for the sweep feature).
