Creat solid by two disconnected surfaces

hi friends, i want to make a solid with two disconnected surfaces,not only i have tried poly surface but i also have tried translating surfaces to curves, i would appreciate your help.

Hi, a good advice in general is to post a screen shot that clearly states which nodes you’re using. Additionally, in this case it would be good to have a Dynamo-file to go on since there may be issues with your particular surfaces. Anyways, here is a suggestion generally involving finding the perimeter curves of the surfaces, lofting that, and then combining everything into a solid. Let us know, if this works out for you! :slight_smile:
