Can you provide some advice on how to draw a rectangular frame in XCS where the lines could be of any width ?

I have an xTool D1 Pro with the extension and the latest version of XCS.

I have tried Scoring a rectangle but I cannot control the width so I assume it is just the width of the beam.

I have tried drawing 4 lines in Engrave mode but when I set the width to 5mm for example it seems to give me a line that goes from corner to corner of a long thin rectangle

I could import a jpeg but I would prefer being able to draw a line of any thickness and be able to resize it without loss of definition. It's easy to do in any other drawing program where output is to print but I can't see a way of doing it in XCS.
