For sure if you are a beginner it is not so easy but here most of the work is already done.
So put your letter as surface/brep on XY plane (front View)
Right click on Brep component and select the multiple surface
And it must work. Except perhaps the Thickness that you’ll have to adjust.
Here a version more simple for you ! Just put your curves. It must work without any change if you use your file posted here.

A question could lead to others paths
Here I made a general cutter for a mesh.
From a mesh, a plane and an angle
Next step implement the straight link. Then multiple cuts with many planes
I added some components to my plugin Nautilus. One to Output text as curve surface and brep. One to find a plane inside an object and one to make the deformation
A Font component outputs all the fonts available
A Text component outputs text as curve, surface or brep depending on a plane, text size, bold, italics, spacing, small cap size. I omitted underline strike through and justification.
