Get me started on this Sink Design

edited March 2015 in Using Onshape
I am trying to design a sink for my bathroom remodel which I will cut on my CNC machine. Problem is I have no idea how to do this design the sink in this picture. I can easily make a rectangle sink with a rectangle hole, but the curve from the surface down to the drain is the problem. I am not even sure what to google. 



thanks in advance

    Additional Details: I plan to carve the sink and the countertop all out of one piece of material that is 36" wide and about 12" from front to back. The sink will be about 4" deep.

    Something like this? https://cad.onshape.com/documents/74b74f0b649e4e95ad6bc367/w/80af11ce5cb8400f8d436252/e/f7cfe341105047afbe8af153

    The sides are vertical and I imagine you'd want them on a bit of an angle, but this should be a good starting point...

    I would start with a box that is roughly the dimensions you want (36" wide, 12" front to back, and 6ish" deep).  I would make this box symmetric about one of the default planes (Front, Top, or Right).  I would then sketch the cross-section profile of the sink and use that to remove it from the box again by removing it symmetric from the default planes.  Then to make it thin I would use a shell on the side and bottom faces leaving the profile you wanted as thin as the shell.

    @FastwayJim I like how you have left a big cutter radius on the inner edges of your model. By the photo I reacon there is all so a slight taper on the side faces which could be done with the draft command.

    @Kyrs it would be great to see some pic's of the whole process from Onshape to bathroom.

    Dang you guys are fast. I will see if I can piece it together by what @jramlseywrote combined with the model that @FastwayJimshared. 

    @BruceBartlett if I can get this thing modeled I would be happy to post a video of the actual product.

    You can make your own private copy of what Jim did and deconstruct his feature list to see what he did.  

    I've modeled up my approach too.

    The only problem is, when I make my own private copy it seems to lose the history.... which is the part I really need to see to be able to learn what steps happened in what order, unless someone wants to make a video of the design process.

    Krys,

    What you need to do next is make this out of concrete... I have built a few of these integral sinks, using concrete. :)

    Couple of questions:

    1) what material are you planning on machining this from?

    2) what type of mill do you have?  How many axis?

    3) what CAM software are you going to program this in?

    4) are you planning on profiling the sink cavity?  Are you going to leave the bottom of the sink square or will you flip it over and then work the bottom?

    5) what type of finish are you looking for?

    Ill try and help you out with solid model

    5) what type of finish are you looking for?

    Ill try and help you out with solid model  

    1) Planning to make this out of 4-6 layers of solid wood butcher block style, then coating it with some clear coat to seal it. This is just a powder bath in my house that doesn't get much traffic. 

    2) I have a 3 axis 4' x 8' CNC router. Its a kit from CNC Router Parts

    3) I will try to CAM this with Aspire/VCarve 8 which I should be able to do with no problems, I also have Autodesk Inventor which has HSMXpress CAM built in as a backup

    4) Not sure what your asking. Probably leave the bottom alone, if I did end up doing both sides I will just have to set up a jig and flip each layer, but design wise I think I will like the look better if it just looks like a solid block of wood with a sink cut into it.

    5) I plan to rough finish with a flat endmill, then do a nice finish pass with either a .25" ball nose or .5" ball nose depending on what I think will look best once the design is done. Glue all the layers together, sand, then stain the piece and add clear coat to seal it.

    Thanks for pitching in, this is all just a side hobby/small money maker for me so it might take me a few weeks or so to complete (much faster with all you CAD experts pitching in).

    @Joe Dunne  That is the plan for my outdoor barbeque/kitchen area.
