Let There Be Light – PhotoView 360 Lighting Tips

Tuesday, March 9th, 2010

I had a customer ask me the other day how they could get more control over the lighting in PhotoView 360. Obviously in its current form PV 360 doesn’t give us a lot of control of lighting and settings. You have the out of the box environments and that is about it. Here are a couple things that you can do to control some aspects of the lighting:

1. You can rotate the environment once it is loaded. This will affect the way the light is cast on the model. To do this, go to Settings, Environment Settings, and change the Environment Rotation. If you grab the arrows on the right you can drag to change the angle.

2. You can load a custom environment file. This is new for 2010. Go to File, Load Environment Image. The environment is not seen but can be reflected in the geometry and can add lighting to the geometry. There are only certain types of files that can add light to the geometry. A “jpg” has color information that can be reflected. An “hdr” file contains light and brightness information that can light up geometry. There are places where you can purchase HDR files. These files are very similar to the environments in PV 360. There are some you can play with under the SolidWorks textures. These are generally used by PhotoWorks and RealView. You can find them under your SolidWorks install directory (C:\Program Files\SolidWorks Corp\SolidWorks\data\Images\textures\background). It appears that you can load an HDR file through the environments to capture lighting effects and then load a background image to set the background. I haven’t played with that process a whole lot, but it seems to allow that.

3. Lastly, you can create geometry in your SolidWorks model that represents a light. Then in PV360 add a light material to the geometry. This object will now cast a light on the model. I create one single surface (not solid) to represent each light. This way, I can use the “hide element” to hide the light in PV360. If you use a solid, you will have to use the hide element for each face of the solid. Just create your lights far enough away from the model that they aren’t seen in the view you want to render. Here is an example model with surface objects as lights. These can be used in conjunction with an environment to highlight a specific area of the model. You could also build an assembly with these light objects and make a reusable studio.

Storage Chest with Lights

PV360 is getting some major enhancements in 2011. Hopefully we’ll have an easier way to create and control lighting effects. Until then, I hope these ideas help you to get the results that you want.

Let’s Go Design

Wednesday, February 17th, 2010

Ever since I was a little Engineering Data Specialist Man, I’ve wanted to design a machine that would help me rule the world. Alas, I never could get the design resources. But wait look what I found…
Let's Go Design

Jeremy has now given me a portal to start my evil plan into action! How perfect -getting the world to help design the very machine that will make me their leader!

I suppose if they do decide to do the collapsible commuter vehicle, that would be cool too. Go check out the site – http://www.letsgodesign.tv. I see this as a great way to learn from each other, improve design and collaboration skills, and have a good time. As they say, no one has ever had a bad time with Luchini!

(one of) The “HIDDEN” relations in SolidWorks – FACE TANGENT

Monday, November 2nd, 2009

Ever want to make a 3D Sketched entity (usually a Spline) TANGENT to a FACE (funky curved face or otherwise), possibly for use as a bridge curve ??
Well in SolidWorks 2009 (and possibly in the past) you can do it.
But it definitely isn’t obvious… :-)

You pick the SPLINE, the FACE you want to make it TANGENT to, AND the EDGE of the face that the spline touches. THEN you get the magic “TANGENT FACE” relation !!
Piece of cake !! (when you know about it…)

3D Controller

Thursday, October 1st, 2009

3D Mouse, Space Mouse, Space Ball, 3D Controller…are they right for me? I’ll answer this questions like I answer most: “It depends.”

A space mouse

If you spend most of your time just working in drawings or if your parts are rather “blocky”, your controller will likely act as a paperweight -taking up room on your desk.

If you work in assemblies or complex parts, your controller will be your best friend. If you disagree with me, you are wrong. (I never lose an argument when I bring out that tough logic!)

When I first got my 3D controller I hated it. I forced myself to use it for a day and I noticed after several hours I did get the hang of it. By the end of the week I could not work without it. Now whenever I am on a machine that does not have a controller, I feel a twitch in my left arm wanting to reach for it. They really do become an extension of your body.

I hear you ask: “Okay Engineering Data Specialist Man, which controller is right for me?” I think there are two considerations:

  1. Ergonomics
    • Obviously the more hours a day you spend designing the more important this will be to you
  2. Function/Command buttons
    • Function buttons allow you to send commands to SolidWorks through the controller rather than the keyboard (i.e. “Zoom to Fit”, “Look normal to selected face”, “Create sketch” …) Some controllers have very few if any buttons, others have a button for every finger on every hand in your entire office. On some controllers, these buttons can be context sensitive, meaning they can even be mapped to do multiple commands depending on what is on your screen. For an example if you are in sketch mode it might start the line command, but if you are in an assembly, the same button might start the mate command. If you are the type of person who has customized every key on your keyboard to do a different SolidWorks command, consider one of these fancy controllers. If you did not know you could customize your keyboard, the most basic models will be all you need.

This is a link to few examples.

Are you sure you are backed up?

Wednesday, September 30th, 2009

I just got off of the phone with a SW Enteprise PDM administrator. I was getting ready to change some database settings and decided to make a backup of their database first. (Better safe than sorry, especially with someone else’s data!) I while making the backup I noticed there were no other backups in existence. Turns out for the past two years this company has not made a single database backup!! The IT guys assumed the Engineering department was making them, and vice versa.

This is the second company in two weeks I have found in this situation.

Backing up your data files on the archive server is NOT the same thing as backing up your database. Please put your mouse down, call your IT guys right now and confirm your company is backing up your Enterprise database.

Stop dancing on the mine field.

Quick Tips for Less Painful Motion Analysis…

Wednesday, July 29th, 2009

I was working on a Motion issue today and thought I would share a few tips that help me set up a Motion Analysis:

Mate all components into their initial position.
Components are expected to move (obviously!!!!) so generally, you want to be able to drag the assembly (in SolidWorks) through the motion you expect to achieve in SW Motion. Once this is done, add a couple of extra mates to lock the assembly into its desired initial position. These can be suppressed within the Motion analysis but they are always there so you can get back to where you started.

Position the model in the graphics window as you would like it to appear in you Motion analysis.
I typically position the assembly as I would like to see it and then create a specific view just for Motion. To create a new view, hit the spacebar to bring up the Orientation View list and select New View which is in the upper left hand corner.

Do these two things before creating the Motion study. It can be tricky to move components or get the appropriate view after the Analysis is created so doing a little pre-analysis footwork can save some headaches.

Start with a simplified version of your assembly.
If dealing with a complex assembly, it can be tough to wrap your head around everything necessary to get everything set up properly within Motion. When possible, I will suppress components, get the partial assembly to run properly, and then reintroduce components. This isn’t always possible but can be very helpful when it is.

Still stuck in 2D? It’s time to consider an upgrade.

Wednesday, July 15th, 2009

It’s that time of year when we all think about upgrading our software to the newest versions. For all you AutoCAD guys, I’ve got a question for you. . . Don’t you wish you could get as excited about upgrades as us 3D guys get?

If you do, and I am pretty sure you do, its time to think about converting to SolidWorks.

Here is just a sampling of the advantages that SolidWorks has over AutoCAD:

1) All changes made to the 3D SolidWorks model will be updated in all locations including all drawing views.

2) SolidWorks will create an accurate BOM that will update when the assembly updates automatically.

3) You have the ability to visualize and check your model in 3D space where in AutoCAD you don’t have that luxury.

4) SolidWorks can accurately display the Mass, Volume, Surface area, Moments of intertia and Center of mass which can all be placed on the drawing with the ability to automatically update when the 3D Model changes.

Right now is a great time to convert to SolidWorks 3D. SolidWorks is offering significant savings on CAD software for qualified companies but only for a limited time. If you register by July 31, 2009, SolidWorks will analyze your business and discuss the return of investment that thousands of companies, large and small, have achieved by already moving to SolidWorks.

What I Learned On My Summer Vacation… (Tips & Tricks from SWworld pt.3)

Wednesday, July 1st, 2009

In a 3D Sketch create a spline perpendicular to a face.
If you just pick the SPLINE and the FACE, you get a TANGENT option. This will try to physically MOVE the spline over to TOUCH the face and be TANGENT with the face. Sometimes this is NOT what you wanted and sometimes you will end up with a NO SOLUTION FOUND problem.
More likely what you want is just for the spline to be TANGENT to the face, but not necessarily TOUCH it also…
Pick the SPLINE, the FACE, and any EDGE on the face and you will get the “hidden relation” TANGENT FACE !
You also of course get a handle that you can use to adjust the magnitude of tangency.

One Milllllllion Licenses!

Wednesday, May 20th, 2009

SolidWorks has hit ONE MILLION LICENSES! I still have a really nice polo shirt that says “200,000 licenses” on it from my second year with 3DVision! Needless to say, it is as obsolete as my Bengals T. J. Houshmandzadeh 84 jersey (Yes, I had to look the spelling up on Wikipedia… hope they were right!)

This is a big milestone for any CAD company. It means they did something right early, continued to innovate and develop, and listened to the user base who keeps coming back for more.

I have been around the SolidWorks community since release 97+. Anyone been around longer? Think you know the history of SolidWorks? Play the Trivia Game here(contains sound)! Watch a personal thank you from CEO Jeff Ray and founder Jon Hirschtick here.

What do you think are the most important things SolidWorks needs to do to if they want to keep this momentum? Submit a comment below…

Shortcut Toolbar Customization

Tuesday, October 21st, 2008

The Shortcut Toolbar is new for SW2008, and is a fantastic edition to the list of those “little things” that makes life easier in SolidWorks.  The toolbar is context sensitive to the environment in which you are currently working.  This means that if you are in the Sketch Environment, hit the “S” key on the keypad, and a list of the commonly used sketch tools pops up right next to your cursor so that is super easy to choose your tool.  Similarly, if you are in the Part Environment, hit the “S” key, and a list of commonly used features found on the Feature Toolbar pops up.  Furthermore, SolidWorks realizes that there may be tools that you commonly use and would like to add to the toolbar.  To do so, simply Right-Click the toolbar and choose Customize.  You will then be provided with the familiar toolbar Customize Window where you can go the Commands Tab and click+drag the desired tool onto your newly customized fancy-dancy Shortcut Toolbar.
