Rob Rodriguez has earned a place for himself as an expert in photo-realistic rendering in fields quite different from the gaming and entertainment worlds. Rob’s expertise is used to help people visualize and make decisions before they make real products. From the architecture we live with to the products that we hold in our hands, Rob’s skills make the things we use better from the beginning. Rob’s business, Axis CAD Solutions, delivers the value and power of rendered images primarily using PhotoWorks from SolidWorks. He also shares his knowledge with others through presentations at annual events like SolidWorks World and at numerous user group meetings throughout the US.    

Q1: How did you first become interested in 3D modeling, animation and rendering? 

Like everyone else I suppose I started designing in 2D with CAD tools like AutoCAD.  I can remember my professors from architectural school saying you have to learn how to visualize your design in 3D as you’re putting it on paper or the screen.  Sometimes this can be difficult when working on a complex design.  I can remember thinking if I can’t “see” the design in 3D then how is the customer going to see it?  2D CAD  was a step up from board drafting but it didn’t solve the problem of visualization for me.  I had worked in the architecture field for a while when I took a position designing decorative cast iron and sheet metal parts for a company that manufactures wood and gas heating appliances.  The decorative cast parts were very free form shapes with a more artistic feel and again I found it very difficult to communicate and visualize this type of design with 2D CAD.  This was the point I jumped into the 3D CAD world using SolidWorks.   I was amazed how much easier it was to “see” my design in 3D since I was working that way on screen.  There was no turning back at that point.  I was in the 3D CAD world to stay and 10 years later I’m still here.  Rendering and animation  just seemed to be a natural progression from modeling.  I used to see very life-like computer generated images while thumbing through trade magazines and they really caught my interest.  I wanted to learn how to create images like this and I’ve been learning ever since.

Q2: What types of 3D modeling, animation and rendering do you do?  

Having been in a number of different industries, I’ve modeled a variety of things.  Residential homes, cabinetry, furniture, sheet metal parts, castings, monuments, mausoleums, etc, etc, etc.  It’s an odd combination really, especially when  people find out I use SolidWorks as my primary design, modeling, and rendering package.  SolidWorks is primarily an MCAD design tool and I’ll be the first to admit some of the things I use SolidWorks to design and render don’t fit with its normal usage.

Q3: What role do your models, animations and renderings play in the product development process? 

That really depends on the context of the work.  If I’m working on consumer type products my renderings and animations typically come at the end of the design process and are used for more of a marketing or sales tool.  Most of my images and animations are used for print brochures, magazines and the web.  If I’m working on an architectural project renderings and animations are used to allow the clients to easily see the design and decide on revisions.

Q4: How much time do you spend, on average, on one particular rendering? 

Typically the modeling is already finished when I need to create a rendering.  I could have created the model at an earlier time myself or my client may have sent me their model to use for rendering purposes.  Since the work of modeling is already completed, the rendering process progresses rather quickly.  I’d say a typical consumer product rendering takes about a ½ day to a day depending on the complexity of the design and what exactly the client wants to show.  Architectural type renderings usually take longer just because the nature of them requires more work.

Q5: What additional software do you use to create your images? 

I like to do as much work as possible in the modeling / rendering package but there is always a bit of post processing required.  For this I use a photo editing program, Corel Draw / PhotoPaint.

Q6: What is your day like?

 I’ll let you know when this one is over J.  It varies greatly but there are some constants.  Having a full time job and operating my own business makes for some long hours.  During the day I would typically be working on design projects for a wide range of customers.  This could include creating models, fabrication drawings, renderings and animations.  I usually have multiple projects happening at once so things can become hectic.  Nights you can usually find me creating renderings for various clients through my own business Axis CAD Solutions LLC.  Again I’m usually working on multiple projects of varying degrees of difficulty  across a wide spectrum of products.  I’ve also branched out into the education side of the software, collaborating on a rendering book for SolidWorks and providing rendering training classes for clients.

Q7: What tips can you share for staying focused on a large project? 

Organization is really the key, especially when you’re working on multiple projects.  Document every detail of each rendering set up, you never know when you’ll need to go back to a particular point in time.  Time management is also very important.  It’s easy to become overwhelmed by  a large project but if you manage your time wisely and work in an organized fashion you’ll be amazed at how quickly it can all come together.

Q8: What part of 3D modeling and rendering do you find most rewarding? 

I really like it when I’m surfing the web or looking at a magazine and I see one of my images.  I can say, “I did that”.

Q9: Just for fun, what is you favorite game?  Movie?  Comic Book?

My all time favorite movie is Rocky I and II.  The whole “David vs. Goliath” theme appeals to me, probably because I’ve felt like the underdog most of my life.  Sci-fi action movies appeal to me the most, probably because of the special effects.  I’m always fascinated by how “real” it all looks in the movies. Star Wars, The Matrix, Alien, all great flicks.

Thanks, Rob, for taking time from your busy work and travel schedule to help 3DVIA visitors understand a little bit more about other areas of the world where 3D models are making a big difference.

3DVIA.com is a place where all of those creators and their 3D models can come together to show their results, explore other parts of the 3D model creation world and to learn from each other. Imagination and fun drive the users, which makes 3DVIA.com a place to enjoy yourself!

SolidWorks is an excellent tool for creating 3D models. Those models are used throughout the conceptualization, development, manufacturing, marketing and sales of many of products that we use every day. It is also a creative tool that is used for lots of fun projects. Many SolidWorks models have been uploaded to 3DVIA.com already (you can find them all at one time using this link).

One thing you may notice about some of the uploaded SolidWorks models, is that the models aren’t oriented in a natural way. They’re often lying on their side or on their back. This post is meant to help you avoid that when you upload your SolidWorks models.

The first image shows a model (by “anonymous”) as oriented in SolidWorks after I downloaded it from 3D Content Central. After I created a 3DXML file in SolidWorks (by using the drop-down list in either SolidWorks 2007 or 2008 to “Save as type:” 3DXML), I uploaded it to my free 3DVIA.com account. The second and third images show the results when I displayed it in first the 3D XML Player and then the 3DVIA Player.

What happened? It all comes down to where your axes are in your SolidWorks model. SolidWorks uses the Reference Triad to indicate this. The following is from SolidWorks Help (with my highlight of the triad).

If you don’t see a triad at all in your models, use the simple 1-2 steps shown in the image above to turn the triad back on.

The image below shows the DEFAULT SolidWorks triad on the left, and the way we want it to be oriented on the right.

Depending on your default part and assembly template files, your triad may be in a totally different orientation. Whatever spatial orientation your files are in, you can download and use the appropriate SolidWorks assembly file template below to easily get good upload results without changing your own templates.

sw_2007_3dvia_upload.ASMDOT  or  sw_2008_3dvia_upload.ASMDOT

Just be sure to put them where you can find them and use “Tools>Options>System Options>File Locations>Default Templates” to make their location easily accessible within SolidWorks.

Each template’s default opening screen has the triad placed correctly and a standard view added (just hit the space bar to see the list), so that you can easily go back to the “3DVIA Upload” view.

Whether you have a SolidWorks part or assembly, the fastest way to get it oriented correctly is to open a new assembly using the new downloaded template. If your model is already open and shows as a choice to insert into your new assembly, then select it and click the green check. This will put the model at the origin in your new assembly.

Or, you can split your viewing screen (”Window>Tile Horizontally”), so that you can see your model and the new assembly. Click on your model’s title in the Feature Manager Design Tree and drag and drop it onto the origin in the Feature Manager Design Tree of the new file. Don’t worry about orientation, just get it in there.

Save it with some appropriate name so that you won’t forget that it has been re-oriented.

Now, go into the Feature Manager Design Tree of the new file and right click on the name of the item that you brought in and then click on “Float” in the resulting list of choices.

All of the mates you carefully set up in the parent model will stay locked as you spin the model to the orientation that you want it to show up on 3DVIA.com using “Rotate Component” or “Move with triad”. You are only trying to get it in the ballpark, not exactly where you want it.

 I use “Rotate Component” because I can whip it around in all three axes, rather than one at a time. While you do this, your reference triad should not move. Do not use “Rotate View” or you’ll have to go back to the pre-set view to correct your triad position.

Next, you’ll need to mate the planes to match your new view. This will ensure that your model sits on the floor, rather than being at an odd angle. Depending on your naming conventions, you may have “Front, Top, and Right”; “1,2, and 3″; or goodness only knows what else. Just match up the closest plane in the model to the closest plane in the assembly. Create coincident mates one by one until your model is locked in .

Now, after a ctrl Q and a save, you’ll be ready to save it as a 3DXML file. Please note that the shadows still won’t show correctly until the file is saved, closed, and reopened.

When your 3DXML file is uploaded to your model selection at 3DVIA.com, it will display correctly in the thumbnail and in both 3D players.

There are always many ways to do anything in SolidWorks, so feel free to follow your own path, based on your own experience. This is just one reliable way to get good results.

Please be aware that 3DVIA.com has an upload file size limit of 10MB, so be sure to check the size of your file before you try to upload it. The upload process will assume that the file is within the limit, so it chugs merrily along (while you wait and wait) and then, at the end, if it’s too big it gives you an error.

If your file is too big you can zip it and (as long as the resulting zip file is now less than 10MB) you should be OK to upload.

Now you can quickly modify and upload your SolidWorks models to 3DVIA.com and know that other folks will see them the way you intended. Have fun exploring all of the other models - there’s a lot to see.

P.S. Feel free to contact me directly if you have questions or suggestions.
