Reference mark of extraction
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.
