I have a question. How can I change my tools what I equipped? Because buttons 1-3 is not working to me.
So confused with your question - the topic is almost 40 days old.
Are you having trouble.. making.. an item? or... assembling one?
to assemble parts - they have to be ontop of the workbench - the purple-ish clothed area on the workbench - too far down or too far up and they won't combine with things.
To make parts - you need to have heated ingots on the anvil before you can switch to the different categories in the radial select menu.
To switch to higher tier tools - you need to select the tool you're switching. - Tin Pickaxe? Select #3 (copper pick, likely) (you won't need to select #3 if its empty, it'll automatically fill the spot)
Iron Hammer? must select #1 - the hammer slot - can't be on axe or Pickaxe and try and equip a hammer - it won't work.
Titanium Axe? must select #2 - can't be on hammer or pick.
alright - I reread the page.
... Still kinda confused at question.
since the page was actually about keyboard issues and not being able to properly select tools and then later, upgrade them.
If that's your problem too, which it didn't look like when I read your comment - then either try changing controls in menu to whatever buttons work for you - or changing keyboard language
