Visicut - where’s my design gone

At Manchester Hackspace we use Visicut to send files to our laser cutter. It works beautifully with Inkscape svg’s and dxf files from anywhere. Unfortunately however, when you import an SVG from another program (I personally favour Affinity Designer), even if you pass it through Inkscape it sometimes does this:

Wait, where did my design go? Oh, there it is, that’s not the size it should be:

This is extremely frustrating but there is a solution, albeit a horribly hacky one, and you don’t have to redraw your design in Inkscape. If you click on that fragment of width measurement you get this popup:

You can now give your design a more sensible width (ideally the one you want it to end up). It still wont be visible though:

However, you can now just about see the height label. If you click on it you’ll get the height dialog:

Once you’ve set the height back to what it should be your design will reappear and you can cut it as usual.
