**SALOME NoteBook** allows defining variables to be used for
creation and modification of objects.

**“Setting of variables in SALOME NoteBook”**

**“Use of variables to add a node in MESH module”**

The following limitations on the use of variables still exist:

*Radial Prism*hypothesis - parametrical values are correctly applied, but they are not restored after “Update study” operation.*1D Meshing Hypotheses*hypothesis, Distribution with Table Density and Distribution with Analytic Density - parametrical values are not applicable.*Translation*dialog box, default mode (translation by two points) - parametrical values are correctly applied, but they are not restored after “Update study” operation.*Merging nodes*dialog box - parametrical value (tolerance of coincident nodes detection) is correctly applied, but it is not restored after “Update study” operation.*Revolution*dialog box - it is impossible to use the angle of revolution as “total angle” if it is defined as variable.*Extrusion along Path*dialog box - it is impossible to use “Linear variation of the angles” mode if at least one of those angles is defined as variable.*Pattern mapping*dialog box - parametrical values (indices of nodes) are correctly applied, but they are not restored after “Update study” operation.*Clipping*dialog box.**Properties**dialog box.
