Dividing a Bowi

chandrashekar_r

I am designing an automatic pet feeder and I have successfully created a bowl

Now requesting help for

1. I need to create five parititions in the bowl and one parition I need to open at the bottom
2. The five partitions should join in the middle where i need a 6 mm hole to mount a dc motor

First, think of the center column as integral part of the bowl. That'll bring you to see the bowl a s a rotational part, not an extruded part. You might then want to check out the "Rib" feature. Create one rib and then use the "Circular Pattern" feature to make the other four or so. You'd maybe end up with something like this:

Take a look at the feature tree, and move the grey bar from the bottom up to the respective feature to see what happened:

The first three (Container Sketch, Depth Extrude and Shell Extrude) are yours.

You can use the rollback bar to go through the steps: I made a sketch of the cross section and the centerline. Then I rotated that sketch around the axis, creating a surface with a thickness as an option. Next, I sketched a line to define the upper linit of the rib, then used the rib tool to create it, including a dratft option. That gave me one intersection. I replicated this intersection 4 times by using the circular pattern tool. I added the small fillets at the end (i though Ishould have added them only to the first rib, in fact, and then incude them in the pattern, but that did not work. So adding the fillets later is but a workaround for a possible bug).

You should probably go though the basics of the learning section: Click on the little head-with-gears-in-it-icon at the top right of the Onshape-window.
