GenDesign and Topology Optimization in Solid Edge 2020

Generative Design Introduction

Generative Design was introduced in Solid Edge ST10 where you can define a specific material, design space, permissible loads and constraints, and target weight and the topology optimization engine automagically computes the geometric solution.

Topology optimization determines the most efficient material distribution to meet the exact performance requirements of a part. It takes into consideration the given space allowed, load conditions of the part and maximum stresses allowed in the material.


It doesn’t matter if the model was created using sketch based features or synchronous or was even an imported IGES, STEP, ACIS or Parasolid file. The Generative Design tool in Solid Edge adds and removes the material between the design features to make the part optimally stiff and lightweight. It also smoothens and blends surfaces to minimize stress concentrations.

I had also written a detailed tutorial about the steps to be performed in Solid Edge to do a topology optimization study for a bicycle frame.

Solid Edge -  A Product Design Portfolio

Siemens PLM's mainstream application Solid Edge is no longer just a CAD program. It is a portfolio of products geared towards helping small enterprises to realize their digital transformation goals. 



The benefits of generative design range from lighter components to minimal downstream manufacturing material waste. Also, highly customized complex shapes can result, perfect for casting or today’s high-resolution additive manufacturing processes. With generative design, you can create the optimum design between weight and strength, tailored for desired manufacturing processes.

Solid Edge 2020 Makes a Splash

Industry leader Siemens PLM's mainstream application Solid Edge is no longer just a CAD program. It is a portfolio of products geared towards helping you to realize your digital transformation goals. The digital transformation is not confined to a product or its design. The scope of this transformation is enterprise-wide and ranging from product conception, requirements management, design, review, prototyping, pilot testing using built-in simulation to manufacturing and downstream post-production activities like servicing and maintainability. 

This is increasingly evident from the ever-growing modules that were introduced over the past few years and culminating during the ongoing RealizeLIVE event at the COBO Center in Detroit. The latest avatar Solid Edge 2020 introduces expanded capabilities to add MBD (model based definition) information to your designs and publish this information using interactive 3D PDF documents.

Siemens is effectively leveraging its $10 billion in recent investments acquiring advanced technologies (e.g. Mentor, Polarion, HEEDS), delivering powerful functionality to small and mid-sized manufacturers via the Solid Edge brand. It is now possible for small enterprises to digitalize more of their product development processes with Solid Edge 2020.

  
I am at the COBO Center in Detroit for the RealizeLIVE event and the atmosphere out here is charged with excitement about the latest release of Solid Edge. My first impressions about the product are very positive due the mind-boggling number of new features and functionalities introduced with this version. It is hard to believe that so much functionality could be made available in just one version alone.
  
New features in Solid Edge 2020 include several industry firsts such as augmented reality, expanded validation tools, model-based definition, and 2D Nesting – combined with extensive enhancements to core CAD capabilities apart form enhanced collaboration and the ability to completely digitalize the design-to-manufacturing process.
  
Here's a quick overview of the Solid Edge product portfolio:
  
Mechanical Design: Visualize and validate your ideas with next-generation technology, from augmented reality to MDB
  


Electrical Design: Electromechanical design as it’s meant to be a seamless integration of ECAD and MCAD
Manufacturing: Fully optimized additive and subtractive manufacturing

Simulation: Put your designs in motion with simulation tools built for designers, powerful enough for analysts.

Technical Publications: Communicate your digital design documentation globally

Data Management: Scalable, searchable and manageable data

Collaboration: Secure storage, viewing, and markup of CAD files available for free at Solid Edge Portal.


My favorite enhancements in Solid Edge 2020 are:

1. 2D Nesting. This is going to be a real time-saver since it is built-in seamlessly inside of Solid Edge and I do not have to export and import data from other nesting programs.


2. Enhancements in Reverse Engineering such as section sketches which creates sketch sections from mesh bodies which can be used to create bodies and features directly instead of taking the longer surface extraction route and ReMesh which helps in making the facets more uniform and reduces file size as well.

3. Part Compare: This has been a long standing demand by users where two revisions of a part can be quickly compared for material addition and removal the results reported via neat PDF file including volume, weight and surface area changes.

Besides those some core enhancements to the design modules like sheet metal bend treatments leading to accurate flt-patterns and auto-scalable sketches are going to be very useful in daily drawing generation process.
   
Also noteworthy is the capability to perform harmonic vibration simulation.
   
Talking with fellow Solid Edge customers in attendance at the event, I found them to be buzzing about the expanded breadth of functionality as well as all the enhancement to the core mechanical design functionality of Solid Edge such as vertex mapping for sheet metal and bend treatments for accurate flat patterns.

All-in-all it is yet another impressive release of Solid Edge which has strongly evolved as a product portfolio with several industry-first features and functionalities. With Solid Edge 2020, Siemens is making advanced digital technologies more accessible, more affordable and easier to use for more and more people. Not only large enterprises can benefit from digital transformation, now small enterprises can benefit too, thanks to Solid Edge 2020.

Solid Edge App - Show or Hide Surfaces

This little app toggles the display of the surfaces generated by the Extract command on the Reverse Engineering tab on the ribbon bar.

Background and usage:

When you bring in scanned data into Solid Edge in the form of an STL file, the Automatic command on the Reverse Engineering tab colors the various regions and further the Extract command creates various types of surfaces automatically, in huge numbers:

1. Planar
2. Spherical
3. Conical
4. BSpline
5. Cylindrical

It becomes cumbersome to show/hide these surfaces manually, specifically when you want to hide all surfaces of one type, say Spherical, or just the BSpline surfaces.

This free macro from www.CADVertex.com helps you quickly toggle the display of each type of surfaces with one click.



Below is the page with the download link and the explainer video:

http://www.cadvertex.com/download.htm

[Download the 3rd app in the 7th bunch or search for show/hide surfaces on that page]

Notes: 
1. There are absolutely no error or conditional checks included in the macro.
2. It is presumed that you have not renamed the surfaces in the Pathfinder.
3. The checkboxes are all ON initially and do not mean all surface types too are visible in Solid Edge.

Solid Edge Video Quick Tip #076

This Solid Edge video tip is about using the Recognize Holes and Recognize Hole Patterns commands in conjunction with the Create 3D, Part Copy, and Scale Body commands.

Unrelated commands like Part Copy and Create 3D have been in existence since the earliest releases of Solid Edge, while ST1 for the first time in the history of any CAD enabled importing dumb geometry and modifying its features like they were created natively. Scale Body, on the other hand, was introduced only recently in ST10. What do these commands have in common?

Well, there is a combo of post-processing commands that render the outcome of these features meaningful. The commands are Recognize Holes introduced in ST5 and Recognize Hole Pattern which was new in ST6. Let's take a closer look at each of these and how the duo recognition commands compliment them.

Solid Edge Video Quick Tip #074

This tip is about temporarily reorienting parts when inserting them into the assembly in Solid Edge.

Parts are often created with an orientation different from their placement in the assembly. After inserting parts in an assembly with the default orientation, it may pose problems with mating them. 

To avoid this, it would be very helpful if parts could be temporarily reoriented, close to the desired position in the assembly. This can be done in the preview area of the Library.

If the preview is not displayed, right click in a blank area between the file names and select Preview...
Check ON the preview and set it to Interactive for both parts and assemblies. Before dropping the bolt into the assembly, rotate it in the preview area.

You can also zoom and pan using the keyboard and mouse button combinations, as shown in the tooltip. 

Now the part is inserted into the assembly, in the same orientation as that in the preview and also mates correctly.

Solid Edge Video Quick Tip #071

This video tip is about exploding a sub-assembly as a single unit in the E.R.A. environment.

The E.R.A. environment is used for exploding assemblies in Solid Edge. By default you are not allowed to pick a sub-assembly to explode. You must explode one part at a time and this can become time consuming and cumbersome.

To overcome this problem:
  1. Select the sub-assembly in the path finder.
  2. Click Bind in the Modify group on the ribbon bar.
  3. This binds all parts of the sub-assembly together.
  4. Start the explode command and pick any part of the sub-assembly.
  5. The entire sub-assembly can now be picked as a single unit.
  6. Finally, select the sub-assembly again from the path finder and click un-bind from the ribbon.
