          We don't know what the part is supposed to look like or what the question is? I assume it's Mass??

            Did you measure the mass of the part I sent and get 13206.4,  I get 13212.32 grams when I measure it.

             

            Thanks

              Your issue is in Cut-Extrude4. You have some odd short lines in the corner that have no need to be there & your arc is not tangent to your connecting lines.

              Once I corrected this I got the mass that you stated was correct.

                  Thanks so much, after removing the short lines and making both lines end points horizontal and vertical to the arc center point and the lines tangent to the arc I finally got the right answer, it's amazing how such a small mistake can sometimes drive me nuts, I have only been using Solid Works for the past few months and need all the help I can get. Again, thanks for your help.

                        Do yourself a favor and go through the SWX tutorials, under Help.  Avail yourself of all the training you can.  SWX is a great piece of software (with the exception of the bugs!).  Do yourself a favor and look for the different ways you can do something.  Sometimes it is as simple as picking things in a different order, sometimes it is a totally different approach to the model such as starting out a part as sheet metal vs. converting a shape to sheet metal.

                         

                        By all means learn about the manufacturing processes that would be used to make the part.  In many cases this will (and should) influence your modeling technique.  For instance, a part turned on a lathe could/should be modeled very differently from a part made on a mill, or where will the parting lines and draft be for an injection molded part.  Design intent is a phrase you'll see here and in the SWX training, and for good reason.

                         

                        It is great software, but unless you understand the manufacturing processes you are inherently specifying you can end up being nothing more than a 3D cartoonist.
