Surface Treatment Assignment

Use the Surface Treatment Assignment window to select the elements to assign the surface treatment to, the surface treatment to be applied and where it is to be applied.

Select Elements

The Scope definition area of the window assists in selecting database elements to assign surface treatment to and displays them in the Selected elements area of the window in a grid.

The Scope Definition drop-down options list can be used to filter by a particular element type, For example, if PIPE is selected and a ZONE containing only EQUI elements is selected, the Selected elements grid does not display any results. Similarly, if EQUI is selected and a ZONE containing only EQUI elements is selected, only the EQUI elements are displayed in the grid. However, if ALL is selected the Zone containing only EQUI elements displays the NOZZ elements as well.

The radio buttons in the Scope definition area have the following functionality:

CE mem

Includes members of the current element, such as elements owned by the CE.

ID

Enables item(s) to be graphically picked from the 3D view.

CE

Includes the current element only.

Collection

The Collection radio button and its associated options list, is only enabled if one or more collections are defined. The options list adjacent contains all the currently defined collections and allows the selection of items from predefined lists.

Click Select or Add Item to populate the Selected elements grid with the elements based on the chosen method and criteria.

The Select option clears the grid of any existing elements and adds the selected items.

The Add Item option appends the selected items to the items already displayed in the grid.

Note:
Surface treatments are referenced by Design elements through the attributes Inprtref and Ouprtref representing the inside surface treatment and the outside surface treatment respectively. Only elements with these attributes can have a surface treatment assigned to them. Therefore only items which have Inprtref and Ouprtref attributes are added to the grid. Items without these attributes are ignored.

Once the Selected elements grid is populated, elements from the grid must be selected to apply the surface treatment. Selections can be made from the grid using standard Windows selection methods.
