So I started to cut out the rough shapes from a cube (using the boolean modifier)
Then I tried to clean up the geometry to be able to round the edges of the handguard.
But it does not work. When I try to bevel it like in the last pic top right it just gets really messy.
I think I took the wrong approach. How would you go about adding clean and workable geometry to such a piece and would you use the Bevel tool to create the round shapes?
