Combining two surfaces to create one surface

I have a model that has a certain surface that when importing created 2 separate surfaces that i want to make one surface. Here is a before and after of what i want to do. I just dont know the command to combine them.


Hi @thallam,
this sounds like you need the unite command.

create surface rectangle width 1 zplane 
create surface circle radius 1 zplane 
move Surface 1 x -0.25 
move Surface 2 x 0.5 preview 
move Surface 2 x 0.5 
unite surface 1 2

Cubit>unite surface 2018 2063

ERROR: Surface 2018 cannot be included because it includes higher order topology

I get this error. And the surfaces are not overlapping

Can you share your geometry please?
