+
+The profile is used for definition of a stream cross-section or as a base of extrusion to generate a channel or digue.
+
+The 2D profiles are built/defined in a 2D space (U, Z). The coordinate U is parametric coordinate, it has no unit. The coordinate Z is real altitude (in meters).
+
+To build 2D profile Use function
+
+ - \ref create_profile "Create profile".
+
+
+
+2D profile object is internal data model object and can not be shown in OCC viewer. 2D profile names are colored in red in object browser.
+
+
+
+Created 2D profiles should be positioned in 3D space using Georeferencement to be converted into 3D profiles:
+
+- \ref georeferencement_profile "Profile georeferencement".
+
+
+3D profile is 3D wire describing profile curve in 3d space.
+3D profile names are colored in black in object browser.
+
+
+Both 2D and 3D profiles can be imported from external file:
+
+ - \ref import_profile "Import profile"
