do not use the booleans tool.exspecialy if your new.this tool is nothing but trouble.do you see where you got the arm into the body turn on wireframe on shaded cut along the body around the arms delet the faces combined both peices of geometry and merge the verts( use the snap tool to line the verts up)takes five minutes no headaches and works fine.

Select the pieces of geometry you want to combine then Polygons>Combine

Boolean Operations only work on closed geometry, it does have its own issues.

the best way is not to use booleans they just bring more and more trouble

Hi jtg91, I'm new to this 3d stuff but it looks like your doing the Basic Human Modeling tutorial by Kurt. I just completed that tutorial myself and I had the same problem trying to union the arm to the body. both my body and arm dissappeared.

The problem for me was that my arm was not completely inserted into the body. There was a gap between part of my arm and the body (even though it looked inserted). Once I found that stray vertex and moved it into the body, the union worked perfectly. You just gotta make sure the etire edge of the arm is COMPLETELY inserted into the body. As Kurt instructed in the tutorial, increase the width of your border edges and you'll easily see if any parts are not fully inserted.

Even after you perform the union, you still have to go in and merge vertexes, so I agree with everyone else, that sometimes it's better just to marry up the two pieces of geometry, combine them, and then merge the vertexes.
