Setting Large Scale in CATIA V5 Session  

This task shows you how to set large scale in a CATIA session.
CATIA V5 allows you to design in a unique geometrical range. Normally, the range of precision=1µ, model size=1km is used for all industries. A new geometrical range: from 1mm to 100km is available to design large parts in particular for industries like civil infrastructure, pipeline transmission of oil and gas, hydro-electric development.

  1. Select Tools > Options.
    The Options dialog box is displayed.

  2. Select General > Parameters and Measure > Scale tab.

  3. In the Geometry Scale list, select Large Scale. The information and fields under the Description area changes to give technical data and detailed information about Large Scale.

  4. Click OK.
    The new scale is applied only after you restart the CATIA session. A message indicating this is displayed.
  • The scale has to be selected at the beginning of the CATIA session. If the scale is changed, you have to restart CATIA session to take into account the new scale.
  • All documents in a single CATIA V5 session have the same scale. There are no mixed-scale documents in the same session.
  • Large scale is defined by following characteristic values:
    • Precision equal to 0.1mm
    • Working area equal to 10000000mm.
