Due to problems with other software, I am trying to find altervative software in order to georeference DWG Images without a defined coordinate system attatched to them. They are digitized to scale 1:1 and are therefore the upper left coordinate is located in GIS Software at 0 0.

I have FME 2015 (soon to be FME 2016) but cannot see any georeferencing tools.

Performs warping operations on the spatial coordinates of features. It is used to adjust a set of observed input features according to a spatial transform defined by a set of control vectors. This transformer computes an affine (scale, rotation, and offset) transformation based on Control vector features and applies this transformation to the Observed features to generate output, and produces good corrections when the entire set of Observed data requires a single transformation.

Each Control feature represents a control vector whose start point is at some location in the original Observed data space, and whose end point is at the corresponding location in the desired output data space. The control vector represents the correction required to go from the observed vertex to the desired vertex. (Control vectors with only one point are interpreted as a requirement that this location not change from the observed dataset to the reference dataset. This is often referred to as a tie point.)

Performs an affine transformation on the coordinates of the feature.

An affine transformation preserves lines and parallelism in geometry. That is, any lines that were parallel before the transformation are parallel after the transformation. In addition, if a number of points falling on a straight line are transformed, the resulting coordinates will fall on a straight line in the new coordinate system.

Affine transformations include translations, rotations, scalings, and reflections.
