To ensure that all drawing information is visible when plotting from an ISO A3 layout to an ISO A4 sheet size, the correct plot settings need to be applied.

Open the Plot Dialog:

Type PLOT in the command line and press Enter.

Set Plot Area:

In the Plot dialog, set the "Plot Area" to Extents. This ensures that everything within the drawing extents will be included in the plot.

Adjust Plot Scale:

Set the "Plot Scale" to Fit to paper. This option will automatically scale the drawing to fit within the ISO A4 sheet size (297 mm x 210 mm).

Other Settings:

Ensure that the correct printer/plotter and paper size (ISO A4) are selected.

Optionally, check the "Center the plot" option to ensure the drawing is centered on the sheet.

Save Changes:

Click on the "Preview" button to check the output. If everything looks correct, click "OK" to plot the drawing.
