Weldment question

[Anonymous]

First "Happy News Years" all, Can I use Inventor weldment tools to weld
sections of plastic material together, to form a water tank? TIA, Bob

Hi Bob,

Yes you can however we only supplied a few pre-defined weldment materials
(assuming you want to do fillet-type welds). You can define your own
material for your weld bead - give it the material properties of the plastic
you are using.

Or,

Use the "cosmetic" weld type.

Thanks Gary, well the cosmetic weld type give me the look, which is obtained
after surfacing (grinding or machining) the weld bead?

Typically water tanks are welded from PolyPro or Polyethylene using
small rod of matching material. These plastic welds are a stack of
round "beads". The process is similar to what kids might do with a tube
of toothpaste if left unattended too long. The corners are typically
pushed down with a big ball tip while the material is still hot.

If a realistic looking weld is desired, it might make more sense to do a
sweep of 3 circles all tangent to each other. Another option might be
to create a chamfer or fillet and create a bitmap which looks like
plastic beads and apply that texture to the features.

Bob,

We used the term to indicate that the weld is being "represented" in the
model graphics cosmetically - the solid fillet weld actually creates bead
topology (which gets rendered using a "melted" surface texture). The
"cosmetic" bead does not provide any added mass to the weldment assembly and
you can't do interference checks against it however many more weld types are
(currently) supported via the cosmetic representation.

Both cosmetic and solid fillets recover into your drawing.

I am a total greenhorn on doing weldment drawings. I know from recent
topics here that many people don't show the caterpillar in the IDW but I am
trying to impress a client so....

I tried doing it all in the IDW but since there is no additional machining
afterwards I decided to just do it all from the IDW instead.

The problem is I am trying to add Caterpillar marks to the joint of two
pieces in a "T" looking down at them. I can't seem to select just the short
mating end of the vertical piece, it always just selects the whole edge of
the horizontal piece.
So I figure I will just use the "Start/Stop" button in the Caterpillar tool
But it seems like it is always just picking the start, I can't seem to pick
a stop point, it just always goes to the end of the horizontal edge.

How is the Start/Stop tool supposed to work?
Anyone have any luck or tips for doing something like this?

I got it by making a sketch and drawing a line in the view then using it for
the Caterpillar marks.

I am still curious how you use the "Stop" half of that button though.
