UCS is a local user coordinate system you can use in a drawing view. It is easier to position drawing objects in view, when you can place objects relative to a user-defined point of origin, or a base point, in the drawing view.

Tekla Structures shows the UCS symbol in the current drawing view, when you create, copy, move, or modify objects.

You can define a different point of origin for the UCS for each drawing view, and change the UCS point of origin as often as you like.

The following example shows several views, each with their own UCS.
