Thanks for the positive comments on AxoTools!
AxoTools was not really meant to do drop-shadow type effects, but there may be a way for you to get the results you’re looking for. In the Projection panel’s drop-down menu, choose “Isometric below” from the presets. Now select your text, select the Extrude tool, and drag to the lower right. If you don’t see the Extrude tool, you may have to manually drag it out of the tool “drawer” to make it available.
The Extrude tool will probably feel more natural than the Extrude panel in this case because the arrows on the panel represent a typical top view, so it gets tricky translating that to the document’s bottom view.
For an effect that a drop-shadow filter can’t give you, try setting the projection to something like Turn 70 and Tilt 30, then press Alt/Option as you drag with the Extrude tool. This is a true axonometric projection. Use the dial controls next to the proxy cube preview to try different projection settings, then Undo and extrude again.
You may like the results you get by checking “Apply stroke widths to new art” in the Draw Settings panel, as well as choosing “Shaded object color” for the fill method.
Have fun with it!
