Create multiple lines of text with Geomedia functional attributes

GeoMedia's Functional Attributes can be used to create multi-line text geometries from database attribute values. As an example, I have the following database fields label1 and label2 in my database table as shown in the figure below.

I want to form a multi-line text geometry using label1 as the first line and label2 as the second line. The Functional Attributes can be used to form the multi-lines. Here are the steps.
  1. Select Start > All Programs > GeoMedia > GeoMeda. Open an existing workspace.

  2. Select Analysis > Functional Attributes.

    The Functional Attributes dialog box appears.

  3. Click New.

    The Functional Attribute dialog box appears.

  4. Under Categories, click Geometry. Double click CREATETEXTPOINT under Functions.

  5. In the Expression field, form the following string by keying in or double clicking the names under Attributes.

    CREATETEXTPOINT(Input.Geometry, Input.label1+Constant.NewLine+Input.label2, 0)

    Note: + is the string concatenate operator and Constant.NewLine is the new line character.

  6. Click Add. Then click Close.

  7. Click OK.

    The multi-line text point geometry is created in the Map Window.
