different % infill on design

I’m designing using Tinkercad. Is there a way in Cura to increase the infill of certain select portions of the imported .stl file? I need 1 part stronger than the rest of the design so I think I want the infill greater in that area.
TIA, Phil

Yes. Check out this CHEP video, starting at about the 2 minute mark (the while thing is worth watching): 3 Cura Slicer Setting Tricks For Beginners - YouTube


I like to use Prusa instead. I think it must work the same way more or less. I must check on that.
