This App will allow you to compute a seven-parameter Helmert transformation inside Autodesk® AutoCAD®, use the computed matrix to transform AutoCAD entities, save and load transformation settings to an XML file, display detailed transformation info, visualize transformation on the screen, reverse transformation and adjust (turn on/off) individual parameters.

The seven parameters are:

Tx - Translation along the X axis

Ty - Translation along the Y axis

Tz - Translation along the Z axis

Rx - Rotation about the X axis

Ry - Rotation about the Y axis

Rz - Rotation about the Z axis

Scale - scaling factor
