SolidWorks DXF Output for 2010 – for Waterjet, Laser, ect…

In working with several customers and preparing for my webcast on SolidWorks for Aerospace Component Manufacturers (watch recording here), I realized how powerful the new DXF/DWG output capabilities in SolidWorks 2010 were. Simply put, a manufacturing engineer can output a DXF file from a SolidWorks model without the need to make a detail drawing. This is handy if you are going to the waterjet, flamecutter or laser with a 2D profile. In this article, I plan on showing you methods for exporting to DXF when you have different manufacturing scenarios.

The first scenario is a part that needs to be flamecut or laser cut and does not need to be bent on a press. Step 1: Right click on the face you wish to create 2D DXF output for and choose “Export to DXF/DWG”, choose a filename. Step 2: Modify the options so that the origin is in the right place for the laser software if you wish and choose “OK”. Step 3: Preview the DXF output image. You may remove unwanted geometry, such as fillet radii or hidden lines and choose “Save”.

In my next blog entry I will show you how to export Sheet Metal parts that need to be bent.

SolidWorks Enhanced Interrogation Techniques

interrogation SolidWorks provides ways for you to get your assembly models to talk. You don’t even need to bring in Jack Bauer (a shameless and gratuitous “24″ plug). You will find that the SolidWorks AssemblyXpert will come to the rescue when your model is either behaving badly or not at all.

The most common use for the AssemblyXpert in SolidWorks is to ask the assembly how many parts it has. No need for Sodium Pentathol here. Just go to the Tools… pulldown menu or the Evaluate tab in the Command Manager and choose AssemblyXpert. You will then be presented with a host of stats relating to your design.
assyxpert You will note it spills it’s guts relating to top level components, mates being solved, ect…

I got a great tip from my colleague at CAPINC Al Zullo while he was working with a customer. The customer’s assembly disappeared, all the components in the feature tree were still showing. The zoom to fit command blew the screen to infinity. Once again, we bring in the AssemblyXpert. The tool told us that there was a component “very far away from the origin” and showed a wrench button….click….moved the component into view and the zoom factor fixed itself. He didn’t even need to initiate waterboarding!

Can’t open a SolidWorks Assembly?

This is an oldie but goodie that I showed to a customer yesterday who was having trouble opening a large assembly. In the SolidWorks File… Open dialog box there is an “Advanced” option when opening an assembly. In Windows XP the option is found in the configuration drop down list. In Windows 7 and Vista, there is a check box called “Advanced”. One you click the “Advanced” button you will be presented with a number of choices relating to configurations. Take a look at the pictures below to see this in detail:


The box above shows how a user can configure their assembly before they even open it. The best option here is to choose “new configuration showing assembly structure only”. This will create a configuration where all the parts and sub-assemblies are suppressed. Enter a name for this new configuration and choose “OK” You will see an assembly with no components resolved. Then you can unsuppress the sub-assemblies that you wish to work with.

SolidWorks for Furniture Design

WoodworkingWe conducted an exciting webinar last week showing techniques for using SolidWorks in furniture design. SolidWorks can be applied to the furniture industry or to any industry using wood products. Highlights of this webinar include using SolidWorks standard features for building up wooden frames, using Library Features for wood joining methods and the use of Smart Components for mechanically fastening furniture. Once a standard design is completed, SolidWorks’ parametric capabilities can help you create similar designs very quickly. After attending the webinar users will be provided a link to download a special furniture design library. To view a recording of the webinar’s main topics, go to: https://www1.gotomeeting.com/register/938107521

No more Virtual Components by default…

VirtualPartsIn SolidWorks 2010, there is a new option relating to creating new in-context components in an assembly that may reduce the blood pressure of many SolidWorks users. The new option is “Save new components to external files”. If selected, SolidWorks prompts you to name and save new in-context components to external files, like it used to prior to SolidWorks 2008. If cleared, saves new in-context components in the assembly file as virtual components. I can go on and on about Virtual components and how useful they are, but I will save that for another post.

Probe in SolidWorks Flow Simulation

Screenshot_FlowProbeIn working with one of my clients today, I discovered a hidden gem within SolidWorks Flow Simulation CFD software. My client asked me if we could walk around the model and probe temperatures at certain locations, like you can in SolidWorks Simulation FEA software. The answer is yes. But the tool is well hidden.

With the Probe tool you can see the values of parameters by moving the pointer over Cut Plots and Surface Plots in the graphics area. You can also create callouts showing the values of parameters at the selected point of the plot. Click Flow Simulation, Results, Probe Mode, Probe, or In the Flow Simulation analysis tree, right-click the Results icon and select Probe.

This activates the probe mode. In probe mode the pointer changes to and shows the parameter value at the point of a Cut Plot or Surface Plot, which is under the pointer at the moment. Move the pointer over the plot. You can see how the parameter value changes across the plot. You can create a callout with the parameter value by clicking at the desired point when the probe mode is active. To exit the probe mode, click Flow Simulation, Results, Probe Mode, Probe or in the Flow Simulation analysis tree, right-click the Results icon and select Probe. Once the probe callout is created, you can double-click it to select parameters, which values in this point are shown at the callout. Also, many other options are available by right-click on the probe callout.

I thought they did a great job with this tool. Give it a shot! If you do not have SolidWorks Flow Simulation, contact us for a live demo at your leisure.

Vote for your favorite enhancements online!

SWWorld_TopTenEach year, SolidWorks asks you to vote on the top ten enhancements you would like to see in a future release of the software. They introduced a new Brainstorm tool for SolidWorks World 2009, and they have brought it back for 2010. It lets you submit your favorite enhancement ideas, and allows other SolidWorks users to vote on what they think is the most important. After the voting is complete, the top ten list will be unveiled at SolidWorks World, the biggest SolidWorks event of the year. I made sure to add my favorite enhancement relating to Flow Simulation. Log on and check it out at http://www.solidworks.com/sw/communities/2010_topten.htm.

I’ve got the power!

PowerConsumption In my webcast today on Event-Based Simulation I showed how SolidWorks revolutionizes the way controls and CAD modeling work together. This approach allows you to directly integrate your models with the behaviors you desire, bringing mechanical and electrical design to the forefront while maintaining machine controls flexibility. EBS accomplishes this in a novel way: instead of defining specific times for events, you can start and stop each event in relation to one another. This translates into major savings. Companies can make and modify products in simulation rather than after manufacturing and can avoid a costly rework of the design process.

During today’s webcast I discovered how you can extract detailed quantities relating to components in the design. For example when an simulation is running, you can choose the “results” button on the MotionManager toolbar and then choose a motor component in the MotionManager tree. The selection choices are myriad to say the least. One selection most machine designers are concerned with is Power Consumption, so that they can pick the right sized motor or actuator to handle the movement of a component.

Another possibility is running a static stress analysis during and event-based simulation run. A user can choose to run the static analysis on one or more components during the event simulation. Users can specify if they want to run the simulation during the entire motion run (which may take a while) or choose to run the static study during a small portion of the motion run, during a critical time. This critical time can of course be found by adding a “result” plot to the component in question and running the static study only during the peak of acceleration or power consumption. To learn more, please contact us here at CAPINC.

SolidWorks Enterprise PDM is the BOM!

Bomb-706581 I just ran a webinar that shows how BOM’s created in SolidWorks CAD software are passed intact to EPDM, reducing rework. “Named” BOMs, which can be used beyond the engineering organization, are now associated with the SolidWorks assembly. This means that if a designer changes a part, the BOM is automatically updated. In addition, named BOMs can now be automatically exported to XML format for fast and accurate data transfer to enterprise resource planning (ERP) systems. For more info on EPDM, watch our recorded webinar at https://www1.gotomeeting.com/register/864590625

Create a new view in a Drawing

NewViewHave you ever wanted to to change the orientation of a view in a drawing after you have inserted a view? There is a little know function that allows a user to rotate / pan or zoom in a model view in a drawing. Typically one can use this function to add a dimension to a hidden feature. When you choose the OK button, it then reverts back to the original view position. However, if you want to save the view’s rotated state, use our old friend the space bar to invoke the old school view dialog box. Here, you can save the view orientation, choose the OK check mark and then change the view from the current view to the new view that you just saved. Cool huh? new_view_drawing
