Creating a new Empty Layer

To create a new Layer it is necessary to have a reference layer to get at least its box dimensions. It is also possible to use all its metadata like attributes, srid and visual.
1) Datasource, clicking on directory or Postgis
    - Set the output file name path (dir/layername) or set the datasource and the Layer Name.

2) Reference Layer: choose the layer to be used to extract ONLY its spatial location (box).

3) Properties - inform the attributes of the new layer. At least an identifier and the geometry property must be informed, however its is possible to inform other attributes of types such as string, int64.
Example: adding 2 attributes (id and geom of type Multipolygon)
    - Data Type: Int32
    - Property:  id
    - Default Value
    - Is Auto Number: CLICK
    - Is Required
     Press add

    - Data Type: Geometry                      Geometry Type: MultiPolygon
    - Property:  geom                              SRID: 4618

    - Is Auto Number:
    - Is Required
     Press add

4) Click on PK to make it a primary key on the id attribute.

5) Press OK button at the end.
Creating a new Empty Layer with all metadata of a reference Layer

    - Check all the attributes at the list bellow.
    - Click on PK to make it a primary key on the FID attribute or the most appropriated  one.
    - Except FID (or the identifier) and geometry, you can remove some attributes from the list, clicking on  remove attribute column.

3) Press OK button at the end.

4) Press Yes/NO to the message to copy the other metadata such as Style, SRID, and Encoding.
