> * First, list out the updated layers with status. For example:

The use of this list is to help identify the CAD layers to be updated without need to operate on all CAD layers.

If the QGis layer (shapefile/geopackage) is a *POLYGON* layer, then in the corresponding dxf file all features will be stored in the CAD layer called “Boundary” (it is assigned by default by the QGis algorithm).
11 4 Giulio Di Anastasio
If instead the QGis layer (shapefile/geopackage) is a *LINE* layer, then in the corresponding dxf file all features will be stored in the CAD layer called “Line” (it is assigned by default by the QGis algorithm).
12 4 Giulio Di Anastasio
In this example, the dxf file ‘’V_BLDG_SHED----E” will be used, to be replaced into the Compiled map file. This layer is a POLYGON layer. In the example, directions are given for both POLYGON and LINE layers.

> * Open the file “E-V-BLDG-SHED.dxf”, it will open as blank window.

The next steps are executed by macros, which have been defined differently for POLYGON and for LINE layers.
21 7 Giulio Di Anastasio
If it is a *POLYGON* layer, the first macro will zoom-extent to all the objects in the layer, and then change the current layer from ‘0’ to “Boundary” layer.
22 7 Giulio Di Anastasio
If it is a *LINE* layer, the current layer will be changed to “Line” layer.
23 7 Giulio Di Anastasio
The macro also turns off the visibility of all other layers in the drawing.
24 7 Giulio Di Anastasio
To run the macro:

> * Go to “Manage” menu. In the “Action Recorder” tab, click on the drop-down to see the list of all recorded macros:

28 8 Giulio Di Anastasio
29 8 Giulio Di Anastasio
> * Click on “GrassMacro01” for *POLYGON* layer, or on “LineGrassMacro01” for *LINE* layer.
30 8 Giulio Di Anastasio
> * After selecting, click on “Play” to perform the commands.
31 8 Giulio Di Anastasio
As a result, the Macro performs the zoom-extent of all features in the layer, makes the Boundary/Line layer current, and turns off all other layers.

> * Open the compiled map file, double click on the layer having contents to be replaced (in this case it is “V-BLDG-SHED------E”) to make it current, and turn off all the other layers.

> * Copy the current layer name from the compiled map file and paste it in the file “E-V-BLDG-SHED.dxf” to replace the current layer name “Boundary”.

> * Once the layer name is replaced, run the second Macro “GrassMacro02”: this macro will select all the objects in the layer and copy them in the clipboard/memory.
