How can i fix the surface?

Rhino Rhino for Windows

I’m new to rhino so please bear with me.

I have several instances where the surface does not reach its own edges as seen in the image. What i did was trim the surface using a curve which was then pushed down to create a ledge. What can i do to possibly rebuild or extend the surfaces all the way to the edge ?

Thank you !!

That’s just the render mesh, there is nothing ‘wrong’ with the surface(well unless there is, but that’s unlikely.) Once your objects are joined up, the gaps should go away.

Thanks for the quick reply jim ! just like you said joining all the parts fixed the problem
