How to split a part at a feature such as dovetails?

I would like to create a dovetail feature to split this part in two since it is too large to fit on my 3d print bed. What would be the best way to achieve this? I also thought about dowels. That would lead to another question of how to create the dowels or pegs on one side, then the matching hole on the other - then split the part in two. Thank you in advance.

draw a sketch in the shape of your dovetail. Extrude it as a surface through your part and use it to split it in two.
Thank you, this worked well.
@christopher_luckenbill Your welcome. Pro tip for you (I stole it from a pro). if you extrude the shape of the dovetail as a "thin" and then boolean subtract it from the part you get 2 parts and you get built in tolerance fit when you print it.
There is a free "split by dovetail" feature:

When you do this, is subtracting the tolerance equal to the midplane? I am going to play with this more this evening. I am at work right now so not much time to mess with it. But…it looks like this might be achieving the same thing? Of course this is an exaggerated example.
Yes. the thickness is your tolerance and the depth is the how far you want to extrude it. oh and no need to use boolean. just switch to remove option in the extrude and it'll save you the boolean step. brain fart there forgot about using it to remove material. Got too focused on splitting.
Thank you so much! I appreciate your help :)
This looks interesting. Can you point me to a tutorial or explain how to implement this?
