6 Reasons Why SOLIDWORKS Electrical Beats Out Traditional Electrical Design


We've been hosting several Electrical webcasts each month, sharing articles and information on its benefits, and providing information regularly all about SOLIDWORKS Electrical. Now, we've put together a list of some of our top favorite benefits in SOLIDWORKS Electrical.

But on top of that, we're providing benefits that not only show the capabilities of 3D design but also still bring in traditional electrical design and 2D schematics when you need them. Here are the six reasons why you need SOLIDWORKS Electrical for your electrical designs.

1. Collaborative features for streamlined sharing
You have the ability to do real-time collaboration and updates with SOLIDWORKS Electrical, ensuring that the entire team is on the same page (literally). Instead of waiting for design updates to be pushed manually, everything is updated as you go. Doesn’t that sound better than wasting time while waiting for corrections, updates, and edits?

2. Decrease production costs
One of the biggest issues with the 2D design is dealing with higher production costs because of possible errors in the schematic design and compensating for this degree of error. But with SOLIDWORKS Electrical, you can decrease production costs because not only do you have the 2D design for reference but you can also design, edit, and update within 3D to prevent common errors that equal extra costs.

Did you know you can start and finish your entire electrical project in SOLIDWORKS Electrical? We have a video that shows you how:

3. Multiple features for your reporting and documentation
You have several ways to work with your documentation while in SOLIDWORKS Electrical. In fact, SOLIDWORKS Electrical allows you to create annotations in your documentation, all of which ties in with DraftSight. Everything will work together, rather than having to jump from different software to create documentation and reporting.

4. Auto-routing technology
Instead of having to do routing of wire, cables, and harnesses manually, everything can be done with Electrical's auto-routing technology. This also means routing detail information is available instantly to all users of the project. Auto-routing is available for standard cable topologies, including RF, optical, USB, E-Net, and more.

5. 2D design with 3D design
As mentioned before, you not only get to keep your 2D designs but they can be easily integrated and enhanced with 3D design capabilities. Both of them can work concurrently with your entire team, ensuring every part of the project is completed on time and with as few errors as possible with multiple versions of the same project.

SOLIDWORKS Electrical helps in a wide variety of industries, not just the obvious.

6. Full integration with CircuitWorks, PCB
There is more to this electrical 3D design business than just SOLIDWORKS Electrical—You also have access to CircuitWorks and PCB to go beyond traditional electrical. Your team can work on printed circuit boards and other circuitry work for higher technology projects that all integrate completely with Electrical.

Of course, there are countless other benefits that makes SOLIDWORKS Electrical a go-to tool for millions of electrical engineers, project team leads, and more out there. 

Need more information on SOLIDWORKS Electrical? We have an upcoming webcast with a live demonstration and open Q&A hosted by our in-house Electrical expert David Hofer. Join us on Tuesday, August 16th at 11:00 AM EST by registering today.

Simulation Tech Tip: How can I simulate freezing water expansion?





Now that spring is here ice is probably the last thing on your mind. Unless your designing a product where stress induced from freezing is a problem. One of my customers posed an interesting question.  How might we emulate freezing water in FEA ?





 As you may know water expands when freezing and this can wreak havoc on any structure where water is contained or trapped.  Hence all the lovely pot holes in the spring punishing our fancy alloy wheels.




To emulate the expansion of a water volume as it freezes I followed this basic process:




1. Use the thermal expansion coefficient (CTE) and a temperature boundary to create the expansion.

2. Verify that my CTE creates the desired volumetric expansion of my ice body by simulating the ice body on it's own and checking the change in linear dimensions.

3. Adjust materials stiffness (modulus) to emulate that of ice. This is probably the biggest unknown in the simulation.



The paper referenced in the video has more insight into that variation:

"The Mechanical Properties of Ice", K.F. Voitkovskii , American Meteorological Society, 1960.

Why You Need To Know About Variable Pattern


With the release of SOLIDWORKS 2015, Variable Pattern was added to the available pattern types. For long time users who may have attended training in the past, this addition may go unnoticed. So why is it so important and why should you add it to your repertoire?  The Variable Patterns most radical enhancement was its ability to pattern Reference Geometry. Let that sink in. Yes, you can pattern planes and sketches, not just Features, Faces, and Bodies. Let me give you an example of just how powerful this is.


The example is going to be a decorative swept cut around the jug shown here


The original cut, which happens to be at the top in this case, is actually quite simple. I had to add one extra step to get it to work properly and that is to base the plane’s height off of a simple 2D Reference sketch. Here’s the breakdown of how it is created –

1.    Create a Sketch that need only contain a straight vertical line that ends where you want your plane.

2.     Create a Plane at the proper height using the reference sketch you just created

3. On the Plane, create a Sketch and use the Intersection Curve sketch tool to create a spline where the plane and the face come together 
                                                                                                                
4. Create a Swept cut using the new 2016 functionality that will allow you to type in a circular diameter instead of having to create a circular sketch. Of course, if you want something non-circular then go ahead and sketch                                                                                                     .
                                 
5.  Create the Variable Pattern. The top box will have the Swept Cut. The bottom box will have the reference sketch used for the plane and the plane itself.  Here is what the property manager will look like  
        
6. Once you have the proper features selected you’ll need to “Edit Pattern Table” create the instances of the pattern. As you can see the only real dimension is the dimension of the reference sketch for the plane, hence why we needed to add that sketch even though a plane could’ve been created in that spot without a sketch.

So if you’ve been building your model along with me, you can see the magic of the Variable Pattern. The pattern feature will create a new Reference Plane, a new Intersection Curve, and a new Swept Cut for every instance in the pattern. Image doing this in years past, every cut would have to be created manually. In the image below I was able to put a diamond knurl on a compound curvature surface using the same technique as above, only using two swept cuts and Variable Patterns instead of one. I have attempted this in years past, and was much slower as every groove was created manually.

So hopefully you can see how truly unique and powerful this feature is will be able to apply this to one of your models soon.

Enjoy!

3D Printing for the Injection Molding Process

In the world of injection molding, the amount of challenges that mold makers and part designers face
can be overwhelming. Factors such as weld lines, air traps, balanced fill, and sink marks are just a small handful of issues that can be incredibly detrimental to producing a really good quality plastic part. Many designers utilize different simulation tools to ensure quality, but there is no substitute for being able to hold and touch a physical part, however tooling an aluminum mold for a small volume of parts can be rather expensive and take a fair amount of time to create.  This is where many injection molders are utilizing 3D print their molds saving both time and money when producing low volume production parts and prototypes.


Utilizing Polyjet 3D Printing technology to create molds can be a great option under the right circumstances. These printers use a photopolymer to layer by layer build a molds core and cavity. The mold can be put into a mud base and injected with the actual material that the end use part will be made of. By doing this mold makers can produce parts that are high quality at a fraction of the cost. Granted these molds are not as durable as tradition injection molds but for low volume production 3D printed molds can be a major cost reduction tool.
