Introduction

Moving a CAD model into a new reference system means to change the internal coordinate system of the model from the one decided by the Cad designed, into a new one which suit the need of the inspection.
Even if it is possible and easier to create a reference system as per the Cad model, and then change the coordinate system in ARCO after the synchronization, in certain cases, it is preferred to change directly the model internal reference system.

Pre-requisites

The procedure the change a reference system of a CAD require some care and the basic steps are as follow:

  1. Import the CAD file
  2. Make sure that the current reference system is MAC
  3. Make sure model in synchronized to machine reference system 
  4. Make active the CAD View
  5. Click on Modify - Transformation



The first operation to be done is to fix the orientation of the model even if the origins are not being set yet, after that it will be fixed the origin and then, the last changes are symmetry and scaled.
If some of the described steps are not required, then just skip to the next one.

General Consideration

The model is moving and not the reference system! 
If, when the transformation dialog is open, some part of the model is selected, then that part will be changed, if none of the part is selected then the whole model will be modified.
if the Check box "Make A copy" is set, then the original model will not be deleted otherwise the modified model will substitute the original

Changing the Orientation

In order to rotate a model, the procedure is as follow: 

  1. Select the Rotation about the axis the model needs to rotate
  2. Type the angle for rotation 
  3. Click append 
  4. Click Apply 
  5. Confirm that the rotation is to be applied to the whole model if no selectin was done.

Changing the Orientation

In order to move the model to a new origin,, the procedure is as follow: 

  1. Select the Translation from the list 
  2. Type the value for each axis to be moved
  3. Click append 
  4. Click Apply 
  5. Confirm that the rotation is to be applied to the whole model if no selectin was done.


Making a Symmetry

In order to create symmetrical definition of the model, the procedure is as follow: 

  1. Select the Symmetry plane required for the symmetry from the list
  2. Click append 
  3. Click Apply 
  4. Confirm that the rotation is to be applied to the whole model if no selectin was done.

Changing the Scale of a Model

In order to scale a model, the procedure is as follow: 

  1. Select the Scale from the list
  2. Type the scale factor for each axis
  3. Click append 
  4. Click Apply 
  5. Confirm that the rotation is to be applied to the whole model if no selectin was done.
