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!

Enhancements in SolidWorks 2011

Monday, February 8th, 2010

Wednesday at SolidWorks World has always been my favorite…it is the day they give us a sneak preview into what will be in the next version of SolidWorks. These enhancements aren’t anything to bet the house on…I know of some things they have shown in the past that still aren’t in the product, but for the most part things they promise here are in the software by fall.

new

Here is a list of the “big hitters” as they presented them:

  • Defeature
    • This is a new assembly feature that will make it very easy for you to dumb down your models before giving them to a customer. This will be very helpful so you don’t have to give away all intellectual property if you want to share space claiming information with your customers. In the demo they just picked a few mounting holes and important faces and SolidWorks did the rest of the work of simplifying the model!
  • Revolve up to surface
    • New end condition in the revolve command. No more cleanup after the revolve command or calculating the total number of degrees you want to revolve! Finally!
  • Photoview Preview
    • As you add textures and materials to your design, you can have a little preview window open to see how your changes will look rendered real time.
  • Better Memory Usage
    • Here they showed a graph comparing memory usage doing typical operations for SolidWorks 2010 and 2011 -some operations seemed to improve memory usage by about 20%
  • Plainer Simulation
    • Imagine being able do FEA on a cross section view of your file. Easy to setup and very fast to run right? Then (make sure you are sitting down for this) once you are happy with the results having the ability to extrapolate the cross section results to your full model! The example they used was a symmetrically loaded disk shape…I am hopeful that nearly any symmetrical condition would work. ??
  • Dimension Layouts
    • This will be a nice drawing productivity enhancement. Automatically stagger or space your dimensions in a drawing view.
  • Design Checker in tasks
    • The only SolidWorks Enterprise PDM enhancement they announced. This is a new task that can check your files against the rules you have defined in the design checker. Maybe the design checker will get the respect it deserves now?
  • Lightweight welds
    • Not sure I fully understood this one. It reminded me of cosmetic threads for weld beads…but we’ve had this…I did notice a killer new interface for creating these lightweight welds and some new assembly features (i.e. chamfers and weld gaps) these will make creating weldments from regular parts much easier. (Could this be a key to removing the weldment feature in the future??)
  • Piping enhancements
    • I’m not a piping guy, so I couldn’t tell what was new vs what we already have. Looked pretty easy though
  • Walk through
    • We’ve had the ability to do a walk through with motion, this seemed a little easier to setup and run. They picked the floor face, an upward direction and we able to drive through their model.
  • Feature Lock
    • Imagine making a change to a rather large part. One of the things that makes this process slow is that if SolidWorks decides it wants to rebuild your part, not much you can do but twiddle your thumbs. This option will allow you to select features to not rebuild -makes for a significant performance improvement.

No Lenard Nimoy, but Mark Snider’s acting skills almost made up for it.

Future SolidWorks Enhancements

Sunday, February 7th, 2010

Every Wednesday of SolidWorks World they show the top ten enhancement requests for their next design cycle. Enhancement requests are submitted by users (through the customer portal or via other means) and are an important tool used to determine the direction of future releases. SolidWorks announced that over the last ten years, 70% of all top ten enhancements read at SolidWorks World have made it into the released version of SolidWorks.

Top 10 Enhancements read at SolidWorks World 2010:

TopTen

While I can appreciate all of these enhancements, and would love to have them in the product today…how did #1 become #1? #1 would only affect users a few times a year, how could users pick something that would be used so seldom compared something that could help them perform their everyday tasks? Of these ten, here is how I would have ordered them:

10. SolidWorks should cleanly uninstall itself. (..and many others before this one!)
9. Graphical map of references
8. On the fly equations & Dialog boxes
7. Option to dangle children and not have to delete them
6. Exploded views for weldments
5. Better utilization of CPU/cores
4. Allow more types of assembly features
3. Increase stability
2. Simplify video card requirements (almost the same thing as #3)
1. File compatibility between versions

Technical Alert – Critical Issue

Monday, January 25th, 2010

To all SolidWorks Users and Administrators,

I’d like to make sure you are aware of a critical hotfix that is available for SolidWorks. This hotfix addresses a critical issue that could cause unrecoverable damage to your files and operating system. The reach of this issue has been extremely limited, but do to the critical nature of the issue I wanted to reiterate that you read through the following SolidWorks Technical Alert to see if it applies to your organization. Look for the alert on the customer bulletins page below under “Critical Hotfix for PhotoWorks 64 bit”.

Customer Bulletins

You can find instructions on running the hotfix on the SolidWorks Forums at:

Hotfix Instructions

Over the past couple of days SolidWorks has been very proactive in communicating this to customers. But, on the chance that you haven’t heard, I wanted to post it here as well.

Using the Wacom Cintiq with SolidWorks

Tuesday, January 12th, 2010

In efforts to provide more valuable content to our followers, we decided last year that we would begin making some instructional YouTube videos.  Being the natural guinea pig that I am, I decided to give it a go.  This was just going to be a rough draft version full of spelling errors and horrible editing simply to get some initial feedback from the boss.  Well, almost a year later you might have noticed some of the nice short videos that have been posted up here lately.  Unfortunately, you may have also been one of the 12,000+ people that have seen my initial video experiment.  My only question I have for myself is – why the heck did I find it necessary to record an introduction??  Wow.  Embarrassing…

Anyways, if you haven’t seen it, just search “SolidWorks” on YouTube.  It’s called “Using the Wacom Cintiq with SolidWorks”, and it appears on the very first page of the search results!  Let it be a lesson to all that once you post a video to YouTube, there’s no further editing that can be done to that video (e.g. remove the intro!!).

Property Tab Builder

Wednesday, September 16th, 2009

File properties. I’ve been singing their praises ever since I was a little Engineering Data Specialist Man. A few days ago when I was visiting a customer I noticed they were still using this interface to populate their file properties:

props

I asked if they were still rubbing two sticks together to make fire. That interface is so last year, yet after taking an informal survey I learned many are still using it! Do yourself a favor and look up the  “Property Tab Builder” in the help file. It will help you build an interface that looks something like this:

propertytab

Much nicer?! Checkboxes, radio buttons, drop lists all to make this boring data entry easier. It’s very easy to set up, you certainly will get a ROI after using it a few times. To help get you started, the file I used to create this custom tab is located here.

SolidWorks to Adobe Illustrator

Thursday, September 3rd, 2009

Have you ever noticed you can save a SolidWorks file as an Adobe Illustrator file (.AI)?  Well, it works, but it’s not exactly as good as it sounds.  The entire purpose of Adobe Illustrator is to edit vector graphics.  However, when you save a SW file as an .AI file, it’s the same as saving it as a .JPG and then dragging that into an .AI file (i.e. it exports a raster image – no vectors).  It’s OK though because there’s another process that works perfectly:

  1. Create a drawing of your SW part/assembly in the orientation that you’d like it to appear in Illustrator.
  2. Save your SW drawing file as a .DXF.
  3. Import your .DXF into Illustrator.
  4. Voila!

You can now fully edit the vector version of your drawing view that you created in SolidWorks.  This means you can edit the stroke sizes independently, you can fill areas with solid colors and gradients, you can apply special filters and effects to the image, and anything else you might be able to do in Illustrator.

So that’s the solution for the guy that makes a handful of technical publications a year.  Beyond that, modifying all of your CAD pubs in Illustrator can become very inefficient.  What happens if a change is made to the solid model?  What if you’d like to reorient the angle of the view?  What if you’d like to move a few of the components around?  To deal with any of these questions, you’d have to go back to SolidWorks and start the entire process over again from scratch – making your previous hard work obsolete and useless.

The answer: 3DVia Composer.  I’ve been using this product for a few months now and I love it!  If you’re company makes technical publications based on your solid models, you need to check out the webinar I’ll be hosting on September 22nd, 11:00am-12:00pm.

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.
