Surfaces not connected

Greetings,

Still learning with designing and drawing. I am using Rhinoceros to make a small box ( battery holder with some electronics) , but the surfaces they don't connect , although I dragged them with "object snap"to the right location.

Basically it is 2 boxes , joint together and the sides are joint solids , the rear side looks fine , but the front side is detached. Even if I move the front side a tentth of a milimeter inside the box , it still prints as a loose object. Can anyone tell me what I am doing wrong?

The answer is so close to the title of the thread.....

You need to use the "Separate Connected Surfaces" option on the Mesh dropdown. That will separate the five meshes in the stl into five separate models in S3D. The shape will then slice nicely.

You made the shape up of five separate pieces....and I'm sure Rhinoceros has a decent Boolean addition function that will join the separate pieces together. If you don't use it...or if it messes things up (which Boolean addition does do on occasions) then you can fall back onto S3D's magic option!

@ dkightley: Cool , I thought the Boolean was to "remove" parts , but I with your help I saw there is also a "union" function i n the boolean section. That does exactly as you said in your post. Now it is working fine! .
Many many thanks,
