Making a "Port Tool" in Fusion 360

The finished housing

Earlier this week I finished my sequence valve housing in Fusion 360.  And I learned a quite a bit doing it.

Many of my challenges were learning to use Fusion 360, partially because it's a tool I'm still new to, and there are different ways to do things in Fusion.

But the challenge I'm going to focus on is more one of process, than one of creating shapes in Fusion

The ports where fittings attach

One of the challenges I faced was how to easily model the 6 ports that were located in the housing.

They're all based on the AND-10050 standard.  That means that the ports are similar.  And when I say similar, I mean they're all similar geometry, varying only by size.

Take away the dimensions, and they're the exact same shape

I also recalled that there are special tools for drilling these ports.


In other words, where things can be standardized, they are as standardized as possible

So why do the same thing in Fusion?

We'll, here's how I did it, at least in brief.

First, create a new part in Fusion, locate the parameters, and entered the dimensions from the table found in the standard into the User Parameters section.

The user parameters

Why enter them first as User Parameters?  I can enter them in an orderly fashion, as they're seen in the table, and then enter them as I built, instead of trying to do both at the same time.  I think it's easier, personally.

The cross section for the "port tool".

Next, I built the port, using standard Fusion tools, and calling the user parameters I entered above.  In my case, I created the cross section for the port as a revolved feature.

It's interesting, at least I think, to point out that the finished "port tool" is a solid.  But I'll use this to remove material from the base casting that will be receiving the port I need.

The port tool, as a solid.

So what were the benefits I found to doing it this way?

First of all, I had a tool that was easily reusable and repeatable across as many places, and designs as I needed.

Second, since the AND-10050 port comes in multiple sizes, I could copy the port, change those user
parameters that I created earlier, and create a new port in a matter of minutes.

Inserting into the current design

And since there were several different port sizes in the casting I was reproducing, this proved to be a big time saver.

I effectively created a "template" for the port that I would use as a standard design feature.

Those benefits alone were enough to get me to bite on this method.

Now, all that was left to do was to open the design that needed the port, and insert the solid.

With a little magic from the move and combine command, I was able to subtract the port tool from the casting I needed, and end up with the right port.

But I'll save that one for a post a little later.

I hope this port helped, and if you have any tips on how you've tackled a similar challenge, feel free to leave a comment!

Inserting and moving the solid

Good luck!
