Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?
My guess without seeing your file (or even a screen capture image) is that there is most likely an issue with your sketch.
this forum supports attaching up to 71MB files, so 16MB should be fine
What you do you mean "sent"?
By email?
That doesn't work. You must reply by the web forum.

Sketch1 is not fully defined.
Sketch2 is more complex than needed with duplicated geometry and dimensions. Not fully defined.
Sketch3 is far more complex that needed and not fully defined. (Pattern Faces or Features rather than sketch elements.)
Sketch5 is far more complex that needed and not fully defined. (Pattern Faces or Features rather than sketch elements.) Appears to be duplicate of earlier sketch?
Sketch6 is far more complex that needed and not fully defined. (Pattern Faces or Features rather than sketch elements.)
Sketch7 has unnecessary duplicated dimensions. Fix Sketch1 and Offset.
Sketch9 is far more complex that needed and not fully defined. (Pattern Faces or Features rather than sketch elements.) Appears to be duplicate of earlier sketch?
Extrude2 is unnecessary - Edit Sketch1.
Extrude4 is unnecessary - Edit Sketch1.
Extrude5 is unnecessary - Edit Sketch1.
Extrude12 is unnecessary - Edit Sketch1.
Extrude15 is unnecessary - Edit Extrude1.
Extrude17 is unnecessary - Edit Extrude1.
Extrude20 is unnecessary - Edit Extrude18.
Curved Wall Sketch4 unconstrained?
Curved Wall Sketch5 unconstrained and too complex?
I think you get the idea.
Fully define sketches.
Keep sketches simple - Pattern Faces or Features rather than sketch elements.
Edit sketches or Features rather than using additional features to add/subtract material.
File size will be significantly smaller.
Less computationally expensive and faster.
Edits will be rock-solid robust.
Finally - do you really need the "bricks" or would a cosmetic brick texture suffice?
Thanks for the support.
Created a new drawing and when I do a circular patter and then a rectangular patter on the emboss feature it is still crashing..is this the wrong way to do this ?
i need bricks to 3d print a model
OK, I will present some optimization techniques when I get a chance.
Have you printed a test piece to make sure that the bricks actually print with enough resolution to be useful?
