Todor Latev

A seven-parameter similarity transformation calculator in 3D space.

$50.00/year

This App will allow you to compute a seven-parameter Helmert transformation inside AutodeskĀ® AutoCADĀ®, 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:

  1. Tx - Translation along the X-axis.
  2. Ty - Translation along the Y axis.
  3. Tz - Translation along the Z axis.
  4. Rx - Rotation about the X axis.
  5. Ry - Rotation about the Y axis.
  6. Rz - Rotation about the Z axis.
  7. Scale - scaling factor.
