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.

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!!).

Align Dimension to EDGE

Tuesday, December 29th, 2009

Ever get “stuck” not being able to get a dimension at the right angle/orientation ??
(when manually dimensioning on a drawing…)
Do you know about “ALIGN TO EDGE” ??
Go ahead and place the dimension (in the wrong orientation), then just right click it and choose “ALIGN TO EDGE”. Select some edge of your model that you want the dimension PARALLEL to, and there you go !!
Piece of cake !!

2010 Simulation Studies Enhancements

Tuesday, December 1st, 2009

Hey everyone! Back for another 2010 Simulation What’s New Blog. This one covers a little bit of everything.

Auto-Recover
There is now an option to backup and recover mesh and solution data. To set this up, go to Tools, Options. On the System Options tab, select Backup/Recover. You will see the option to “Save auto-recover info after meshing and after running a simulation study”.

Sim Studies 0

If you use this option, keep an eye on how large your backup folder gets. I can imagine this could make this blow up pretty fast.

Solver Window Improvements
Similar to the changes that were made to the mesh progress window, the Solver Window has been upgraded as well. You can opt to see a condensed solver window like this:

Sim Studies 1

or a more extensive solver window like so:

Sim Studies 2

Fatigue Analysis
You now have to be in a fatigue study to enter an S-N curve. Not sure of the reasoning for this one yet. I wonder how it will affect the creation of custom materials. It is now possible to use the stress values from a specific solution step of nonlinear and linear dynamic analysis for fatigue studies. In a damage plot, damage is now shown as a percentage versus a fraction as it used to be.
A new Fatigue Check Plot has been added to static studies for Simulation Professional seats. It alerts you to areas of the model that may need further investigation due to fatigue issues. It is a “blue is good, red is bad plot” so the red area should get further attention in the form of a fatigue analysis. A single constant-amplitude fatigue event, either fully-reversible or zero based, is used to generate the plot.

Design Study
A new Design Study has been added. This is basically a combination of the old Design Scenarios and the Optimization module. Just as before, the user specifies variables, ranges and goals and the software goes through all the possible combinations to determine the best solution. There is an extensive tutorial on how to use this in the What’s New Document for further investigation.

Offsets for Composites
Previously, the software always positioned the surface used to define the composite shell in the center of the stackup. Now, it can be positioned either in the center, top, bottom or anywhere in between. This is done by specifying an offset ratio. An Offset Ratio of zero, places the surface at the center of the shell. 0.5 places it at the top surface of the shell. -0.5 places it at the bottom of the shell. Interpolation between these values can place the shell anywhere in between as well.

Sim Studies 3

Beams
Beams are now supported for Nonlinear Studies. They have improved the Neutral Axis Detection. Many of you may have noticed that Simulation previously had a hard time detecting beam lengths that were relatively short compared to their width. Anything with a length to width ratio of less than 3 was an issue. The Define Beam Neutral Axis command allows the user to over-ride this. It is now possible to edit the Torsional Rigidity and Shear Factor for Beams. Beams can now be bonded to curved shells and sheet metal bodies. Beam information can also now be added to reports and saved out as an edrawing.

That wraps up this blog entry. As always spay and neuter your pets and if you have any questions, refer to the 2010 What’s New Document or contact us on the support line. See you next time!

Meshing Enhancements in Simulation 2010

Monday, November 16th, 2009

Back for another addition of Simulation 2010 What’s New. Today’s episode covers meshing enhancements. Enjoy!

Curvature-based mesher
There are some improvements to the curvature-based mesher. Compatible meshing is now supported for touching solid faces. Previously, all curvature based meshes were incompatible. The curvature-based mesher now checks for interferences between components. If there are interferences, the following dialog pops up:

Mesh 3

Clicking “Yes” puts you into the interference detection dialog box. The curvature mesher handles small features better than it did in previous versions.

Mixed Meshing
The mesh is now compatible between shells and beams that act as stiffeners.

Memory Usage
The mesher now uses memory more efficiently. The following chart from the What’s New document shows the results of running an h-adaptive mesh on Windows XP 32 bit:

Mesh 2

Shell mesh
You can again define shells by selecting the surface of a solid body. This is something that they took away in the 2009 version. In 2009, only sheet metal of surface bodies could be defined as shells. Enough people must have complained to get them to bring this back.

Mesh Progress Window
They have changed the look of the Mesh Progress Window. It now shows memory usage, elapsed time, the number of components that failed to mesh, and mesh progress.

Mesh 1

That wraps up the discussion of mesh imporvements in Simulation 2010. As always, if you have any questions about anything discussed here, refer to the What’s New documentation or direct questions to us on the support line. See you next time!

2010 Simulation Interface Enhancements

Tuesday, November 10th, 2009

Hey everyone! SolidWorks 2010 is out! There are a lot of small improvements in SolidWorks Simulation. There is nothing earth shattering but there are a lot of long over-due improvements that make Simulation friendlier to use. I will try to put together a series of short blogs that outline the highlights. This entry will cover interface enhancements.

Study tree feature names are now more descriptive. It used to be, unless you manually renamed your features, you had to edit a feature to tell what you had actually applied. This is no longer the case. Most features have descriptions in parentheses next to them in the feature tree.

2010 blog 1

If you hover over an item in the Simulation feature tree, an even more detailed description pops up.

2010 blog 2

2010 blog 3

Hovering over a symbol in the design window also pops up the details.

2010 blog 4

Fixtures, loads, and connectors can now be organized into folders. To do this, right click on Connections, Fixtures, or External Loads and select Create New Folder. Items can then be dragged into the new folder.. When using the Connectors dialog box, and connectors that are created while the dialog box pushpin is depressed will be placed in a new folder. If this is not wanted, the items can be dragged out of the folder back into the general connections folder.

It is now possible to group edit like features. For instance, if you have 25 identical bolt connectors, you can either ctrl select or shift select all the bolts you would like to edit, right click, select edit feature, edit a value in the dialog box, and accept the change. The change will be applied to all the selected connectors.

These may seem like relatively simple interface changes but I think they will make Simulation much more user friendly. As always, if you have any questions about any of the enhancements discussed here, the What’s New documentation is a great source or I would be happy to answer your questions on the support line.

(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…)
(see the video for a visual explanation)

Customizing Enterprise Addin Interface

Wednesday, September 9th, 2009

Years from now we’ll be sitting around the campfire telling our grandchildren of how EPDM 2009 was the version where they greatly improved the SolidWorks addin. The kids won’t believe us when we tell them how hard our lives were before.

That little pane in the bottom of the task pane is pretty sweet eh?
taskpane
…but did you know you can customize it? You can add additional variables to display here too! (By default we only get Description)

In SolidWorks, go to Enterprise options, the view settings tab, find the variable you wish to display

options1

then chose to “display in the preview”. This is a personal preference so any settings you do here are for you only, you don’t have to worry about upsetting Larry and is precious setup….but just for fun switch the order of his little troll dolls.

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.
