CATI Tech Notes

SOLIDWORKS Tips and Tricks and Info on Professional 3D Printing with Stratasys from the Technical staff of CATI


The first things that always get asked from the mold
designer are.

  • What are the steel sizes that I need so I can
    get stuff on order?
  • When are you going to be done?

And not necessarily in that order…..

With the addition of the bounding box feature for multi-bodies in 2013 I was kind of curious as to if this would work for a non planar
mold situation. So I turned my Split into a weldment and sure enough works like
a charm.

The real story here is that you can take any multi-bodied
part and turn it into a weldment. It does not have to contain structural items
to be defined as a weldment just multiple bodies. I didn’t do anything really
exotic here, just a pretty simple non-planar tooling split, which is pretty
typical these days.

After I was done with the split I added in the weldment and
right clicked to update the bodies.

The next right click will give you the ability
to create a bounding box. The bounding boxes are individual 3D sketches that
can be used to propagate dynamic changes to the cut list.

I personally think this has some real advantages as a quick
stock list can be generated for purchasing. 
Its definitely something that Mold and Tooling people have been asking
for for quite some time and have typically either used a couple of workarounds
to get a quick list to order steel or done the “measure and record” method.

Give it a try and let me know what you think
