All the extracted data are done compared to a reference mark and a selected origin.

It is the total reference mark of the model 3D which is selected and used by default (the origin of the model ).

To select a new origin and/or a new reference mark, it is possible to indicate to the choice:

  • A coordinate system .
  • A point , a summit  or an arc of a circle  (Center). In this case, the reference mark will be parallel to the total reference mark of the model .

Only one selection is possible here and this selection replaces the preceding one automatically.

A XYZ outline of the reference mark is constantly displayed.


 


The extracted data are put automatically up to date during the change of reference mark.
