Hi all,

Stupid question but I’m hoping to fill the space between these two curves, I tried loft as well as sweep but I assume there’s a better way. Any help or tidbits is greatly appreciated.

Thanks in advance!

Hi there,
You may try to use offsetSrf with solid property turned on( I assume that is what you want )
