Transform Matrix dialog option reference

Map the coordinate system of the measuring device to the coordinate system of the CAD model.

The Transform Matrix dialog is a common dialog. The options change depending on how the transform is used.

For example, the CAD - Transform Matrix dialog displays a Mirror and Scale button. The Initial Alignment - Transformation Matrix dialog displays a 3-2-1 button.

The dialog can contain the following options:

• Rotation — Rotate the model around a specified axis.
• Translation — Move the model by a specified distance along the X, Y, and Z axes.
• Scale — Increase or decreases the size of the model in the CAD view.
• Mirror — Invert the CAD model in a specified plane.
• Transform List — Sequence the rotation, translation, scale, and mirror composition. You can select and drag items to change the order.
• Delete — Delete the selected transformation.
• Edit — Edit the selected transformation.
• Test — Compare the coordinates of a specified location before and after the transformation.
• Save — Save the transformation as a transformation matrix (.mat) file.
• Load — Load a previously saved transformation matrix or a workplane from a CAD file.
  • Load a .mat file or model file that contains the transformations you want to use. Any existing transformations are deleted.
  • If the model file contains workplanes, you can select the workplane you want to work with.
• 3-2-1 — Create an initial alignment between the Machine Datum and the (PCS) CAD Datum.
  Note: The 3-2-1 button is not available in OMV.
• Invert Matrix — Invert the transformation matrix.

  For example, inverting a matrix that has a scaling of 2 and a rotation of 30 degrees about X produces a rotation of -30 degrees about X and a scaling of 0.5.

Rotation dialog

Rotate the model in a specified axis.

• Axis rotation options are:
  • Around X (YZ Plane) — 0 degrees is along the Y axis; 90 degrees is along the Z axis.
  • Around Y (ZX Plane) — 0 degrees is along the Z axis; 90 degrees is along the X axis.
  • Around Z (XY Plane) — 0 degrees is along the X axis; 90 degrees is along the Y axis.
• Angle (in degrees) — specifies the angle you want to rotate the model in the Axis.

Translation dialog

Move the model along the major axes.

• The X, Y, and Z boxes specify the distance you want to move the model in each axis.

  The button inverts the axis values.

Mirror dialog

Mirror the model.

• Plane — Plane in which you want to mirror the CAD model.
• Coordinate — Position on the selected axis about which you want to mirror the model.

Scale dialog

Increase or decrease the size of the model.

• X, Y, and Z — Location of the centre of expansion relative to the PCS datum.
• Factor — Factor to scale the model.

  For example, to double the size of the model enter 2.

• The button changes the specified Factor to its reciprocal.

  For example, a Factor of 4 changes to 0.25.
