Ok, Im at home and not in front of my computer but I'll try to explain this.

Im trying to void the bottom of a sphere - think magic 8 ball.  But the sphere wont void. 

Here is what I am doing:

1. create a mass (solid) in place.

2. draw circle on level 3

3. create mass, pick sphere. Sphere is createdwith bisecting line, i dont do many spheres, i assume line is normal

4. draw rectangle on level 1

5. creat mass (void) - extrude until it intersects a bit of the bottom the sphere

6. complete operation.  nothing.  doesn't work, the bottom of the sphere is not voided.

I can do this same operation on a 2010 version of Revit and its works, just no my 2012.

Is there a toggle or option Im not aware or is 2012 different in some way?

Help is appreciated.

Just a question, did you used the "Cut Geometry" tool?

I was able to reproudce this problem, but subsequently I've been able to fully cut a sphere several times with a couple of voids.  I don't know.  I've always been wary of Massing, and stick to the basic modeling tools, revolves, sweeps, etc.

thanks Typhoon.  I ended up just doing a revolve to accomplish the shape.  But I'll remember the advice.

OK, I solved the problem, watch the videos:

this is in "Conceptual Mass": http://screencast.com/t/pZb04ebm

and this is in "Project": http://screencast.com/t/7VsysVW5WI

Create the Sphere and the Void in a "Elevation view" and not ina "Plan View"
