- [Instructor] One of them were useful tools
for defining the stock that our part
is going to be machined from
is defining that stock via a sketch.
If we take this circular part here
and define the stock around it,
the bounding box method will create a rectangular box
around our part.
Our stock may not be rectangular.
We might need to use something
other than the bounding box method
if our part is not rectangular.
In this case, a very easy way to define something
other than the rectangular bounding box
would be to draw a sketch and then extrude that sketch
into the material that the part's going to be machined from.
To do that, we need to go back to our sketch tool,
click the surface, start a sketch,
and let's sketch a circle as our stock material.
We go back to SolidWorks CAM,
go back to the stock manager,
and now we can select defined sketch.
We click on our sketch
to find the height of the extrusion,
and we've now defined circular stock material
that will be removed when we're machining our part.
