+Input fields:
+
+- **Main objects** panel contains shapes to be translated. Shapes are selected in 3D OCC viewer or object browser;
+- **First direction** defines translation in the first direction:
+
+ - **Vector of translation** defines vector along which the object will be translated. Vector is edge, axis selected in 3D OCC viewer or object browser;
+ - **Step** defines the distance between the shape copies;
+ - **Nb. Copies** is the number of shape copies;
+
+- **Second direction** check-box turns on/off translation in the second direction:
+
+ - **Vector of translation** defines vector along which the object will be translated. Vector is edge, axis selected in 3D OCC viewer or object browser;
+ - **Step** defines the distance between the shape copies;
+ - **Nb. Copies** defines the number of shape copies.
+
+**TUI Command**: *model.addMultiTranslation(Part_doc, [shape], axis1, step1, Nb1, axis2, step2, Nb2)*
+
+**Arguments**: part + list of shapes in format *model.selection(TYPE, shape)* + 2 axis in format *model.selection(TYPE, shape)*+ 2 real (step values) + 2 integers (Nb. Copies).
