Method ToGeoTransform3

Namespace

Assembly

ToGeoTransform3(Matrix)

Converts a Tekla transformation matrix to a GeometryHelper transformation.

public static GeoTransform3 ToGeoTransform3(this Matrix matrix)

Parameters

matrix Matrix

The Tekla transformation matrix to convert.

Returns

GeoTransform3

The converted GeoTransform3.

Remarks

Tekla stores four rows of three, the fourth row carrying the translation, and applies it on the right for row vectors. GeometryHelper stores a full four by four applied on the left for column vectors, so the two are transposes of each other and the translation moves from the last row to the last column.

Exceptions

ArgumentNullException

Thrown when matrix is null.
