TCL Command SPOINT

Syntax

SPOINT arg1 arg2 arg3 arg4 arg5 arg6

Description

Station points form the basis for the geometry of extrusion bodies. These station points can be assigned additional geometric and other properties that are necessary for the structural analysis. Since these properties often vary in the transverse direction and depend on the structural unit, the possibility of serial input was created, which greatly shortens the input.

Arguments

Minimum quantity: 3

arg1

Value	Dimension	Meaning
sname	TEXT	Station name as specified in the STATIONS scope
[XFTS s1 s2 step]	XFTS	Series of station names; all stations in the series are given the properties specified in the arguments below. The decision whether to use a series of stations or single stations in the export is based on the number of repetitions.

arg-i, i>5 (arg2 = CSECTION)

Value

Meaning

KINK

KEYWORD

2 cross sections at the kink point in different directions

The KINK and KINKA options are used to control polygonal axes. Polygonal axes contain kink points. If the station point lies on a kink point, then a jump in the tangent direction occurs. Since these kinks are exceptions and in the majority of cases the axes are smooth, the program does not check the smoothness of the axis tangent. The user decides how the cross sections are directed at the kink point.

KINKA

KEYWORD

The tangents at the kink point are averaged so that there is a common direction of the cross sections.

arg6 (arg5 = CASCADE)

Value	Dimension	Meaning
ncasc	INT	Number of steps (= number of beam nodes in the cross section)

arg3 (arg2 = VARIABLE)

Value	Dimension	Meaning
vname	TEXT	Name of cross-section variable

arg4 (arg2 = VARIABLE)

Value	Dimension	Meaning
