Sorry for my newbie-like question, but I have forgotten much of what I have learned in MoI due to lack of use.

Is there a way to trim a collection of objects such as those seen in the attached image to create the outside profile. In this case, I want to end up with a heart shape (tip rounded).

I am so used to other software that has tools, such as shape builder in Illustrator, or the trim tools in TurboCAD, that I am blind as to how to approach this in MoI.
