Extruding to part, face, anywhere?

Anytime I think I've got something covered, I find a way to back myself into a corner.

The "block" parts (grey and blue) of this are to be the female support block. IE, the blocks fit and hold the body shape (goldish thing) in place while I drill into the body shape. Makes the drilling more accurate. Well, for me anyway.

Understand, I've done what I thought was this same thing before with y'alls help, but maybe the issue is that the body shape file was made by one of our guys outside of OnShape and I imported it as a STEP file to use? 

Once I exported the blocks to be printed, I noticed that they were just blocks! There is no relief in the blocks that would permit them to close over the body shape.  Call me silly but I didn't expect that so wasn't even looking at them prior to exporting.

Here is the Link and I've allowed OnShape support as well.  TYVM.

Any thoughts are beyond welcome and thanks everyone!

    Use Boolean/Subtract to remove the body shape from the support blocks. "Keep tools" will keep "body for frank 24", otherwise Boolean will consume the part.

    I'm not sure why you expected the body to be removed from the blocks wen there is no feature that would do that in your model...

    Thankfully the fix is simple: just add a boolean feature at the end to subtract the yellow body from the blocks.

    First off, MANY thanks to each of you. 

    Biggest smile was from _anton.  "Fish thingy"  :-)   Indeed it does have a fish like shape but not a fish! But yes, as mentioned the blocks are to make a perfect fit support to the fishy thing.

    Next up, Eric:  I expected it because when I've made molds like this before, the body was removed as it was a separate piece. However, in my successful attempts before I was extruding to part. That is, the body itself. This does not appear to be a choice this go round so that is why I thought that what I did would work.  I now realize that even though the mold halves are different color as does the shape they cover does not mean all parts are what I thought.  I live and I learn.  Now I'll go forth and Boolean! 

    And S1mon, tyvm.   

    Lets mark this as solved.  YOU ALL ROCK.
