Hello,
I need help solidifying mesh circles. I am designing some stuff and am new to blender (I used to use Autodesk Inventor).
somebody help please?
Solidify in what way ? Show us exactly what you have and what you want
If you want something like torus, either just add a torus primitive or use a curve circle and in the curve settings set the ‘Fill’ to Full and increase the bevel depth and bevel resolution settings
