Win, Place, and Show(case)

This is the ongoing story of a mechanical brain slowly making his adventures in the more artistic world of Showcase.

At long last, my engineer's mind has past the point of 'plastic deformation'. You designers and engineers know what I mean. My mind is being stretched past the point where it will no longer snap back to its original limits.

So with the philosophy out of the way, I've been working (at least as much as time will allow), with bringing my Inventor files into Showcase.

As I mentioned in the last blog, the process starts with a 3D model (In my case, it was Inventor, but could be another CAD program).

The first step is to import the model into Showcase using one of the detail options.

Trying to keep things short, here are the steps involved

1. Go to File>Import Models

2. Select your file, and open it. You'll be asked to choose the level of detail that you intend to use.

This isn't the same as the Level of Detail in Inventor (which unloads components from memory). This controls the tessellation (how many facets) the solid uses. The lower the detail, the 'blockier' the solids look. However, they load faster. The higher the detail, the better they look, however, they will load more slowly.





Once you choose your Level of Detail, you can bring in the components by hitting OK. You'll see the import progress screen come up.



3. This completes the import. You're now ready to start applying environments, materials, transforms, and shadows.


Ultimately, you can end up with this:



I'm going to add more to this in further blogs, but in the upcoming weeks, expect to see,

  • Putting the model in an environment
  • Choosing materials
  • Using transforms to orient the model
  • Creating ambient shadows
On a final note, both myself, and my esteemed colleagues at KETIV (Nicole, Mike, Javier, and Jonathan C.) are holding web events in February and March on the following subjects, all at no charge. Please feel free to swing by and take a look. We'd love to see you there.

Happy Inventing! Or perhaps it should be 'showing' in this 'case' (get it? 'Showing' 'Case' = Showcase).

Bad puns aside, good weekend to everyone!

Never use the default password.


I'm in the middle of putting a new Showcase blog together, but I've been pretty busy, so it's not quite ready.

In the meantime, he's a little bit of a PSA (Public Service Announcement), on why you should probably change your default password on, well, just about anything.

This is an actual article off of Foxnews, right here.

So the next time you think of letting the default password slide, think of Austin, Texas.

As for that Showcase post, look for it toward the end of the week!

Making What Works Look Good Too (Autodesk Showcase)




One of my new adventures in 2009 is Autodesk Showcase, and while a grip of fun, has been challenging too.

First of all, what is Showcase anyway, and what does it do?

Showcase is a rendering tool that allows you to take 3D CAD models (even non-Inventor models!) and not only create photo-realistic renderings of them, but will also give you the ability to change colors, camera angles, and visibility in real time. You can literally see what your design is going to look like before it's even left your computer.

So what is the challenge for me?

I'm a mechanical engineer by degree. By definition that makes me the guy who things in a Cartesian coordinate system of X.Y.Z, with a tolerance of plus or minus .005.

Now for the Showcase world, where you hear things like 'that looks better if you move it a smidge'.

What the heck is a 'smidge' anyway? Is that some sort of constant that wasn't in my Dynamic Systems Analysis Course? I don't remember that one!

After deciding a smidge was smaller than a 'nudge' and bigger than a 'little bit', I carried on.

Things are a bit more subjective in the Showcase world, but once I shelved my '+/- .005
brain, I began to see what was possible.

I would have loved to have had this back in the days when I was designing enclosure hardware. It would have saved us days in presentations and trying to make SLA prototypes look real. Not to mention the catalog work we could have gotten done without having to build prototypes for photoshoots!

But the past is the past.

And this is the grips of fun part... making something that works... look good too.

There's a lot that can be talked about in Showcase, so I'll keep the basic steps concise. I thought that before I went in and started talking about 'tips and tricks', I'd just show the basic steps to get from CAD model, to rendering As I 'blog' on, I'll get into more depth in the steps and show you some of the things I get to work on!

First, you import your model


Next, get your model oriented.


Next, apply your materials and insert it into a scene.



With a scene and materials done, you can now calculate the ambient shadows. Once the materials and scene are in, you now have a rendering that you can rotate, modify etc!

True enough, there are subtleties, nuances, and tricks that you can use to make things look even better. It's also true that this is a pretty condensed process described here, but I'll add more soon. I promise!

Happy Friday everyone!

Editing your Dimension Styles Faster!

So, here it is 2009, and I'm still wondering where 2008 went. It seems I was snowboarding in Mammoth only six months ago, now I'm planning the next trip!

Here's a tip I ran across that I sometimes forget myself.

Working with dimension styles can be a little tedious at times. But there's one little thing that has definitely made it a little easier.

Most of us who've been using Inventor for a while know the standard method to editing dimension styles.

That is go to the Format>Styles and Standards pulldown menu, locate the dimension style, and either modify it, or use it to create a new one.


Of course, that brings up the Styles and Standards Editor. While powerful, this can be a pretty intimidating to identify and change the correct dimension style.



Thankfully, there's a way to get to the correct dimension style with a little less headache.

Just choose a dimension that you want to modify or copy, and right click on it.

By choosing 'Edit Dimension Style' you can modify the existing dimension style, changing all the dimensions it affects.



By choosing 'New Dimension Style' you can copy an existing dimension style and alter the copy to create more dimension styles.


These have the advantages of dropping you right into the correct dimension style when you're editing. In the case of creating a new dimension style, you can choose an existing dimension style that most closely suits your desire, and use the 'New Dimension Style' to make a copy you can modify.

Happy 2009 everyone! I hope this proves to be another helpful tip.
