Retain PMI and Design Intent when you translate CAD Models into SOLIDWORKS with ELYSIUM

ELYSIUM CAD Translator

Got a lot of CAD models and drawings to translate into SOLIDWORKS format?  Don’t want to lose your design intent in the process?  If so, keep reading! At SOLIDWORKS World 2018, a Dassault Systèmes team [who brought us SOLIDWORKS as we know it] out of Germany presented an impressively powerful CAD translation solution called ELYSIUM!  This is, without a doubt, the Cadillac of CAD translators. From the original Greek “Elysion” (meaning “abode of the blessed”, as in the afterlife), ELYSIUM is aptly named as it uses native API to translate other CAD formats (such as Catia®, PTC Creo®, Autodesk Inventor®, neutral formats, etc.) into SOLIDWORKS (and other formats) while also preserving any original design intent and PMI (product and manufacturing information), such as would be used for MBD (model-based definition), CNC machining, automated inspection, etc. It sounds like ELYSIUM literally rebuilds the original model or drawing, from the ground up,…

SolidWorks Tutorial: Import Diagnostics (4) – Sheet Metal Conversion [VIDEO]

This is the fourth in a series of articles focused on troubleshooting and healing topological errors from geometry imported in SolidWorks. After we demonstrated the power of the Import Diagnostics tool for healing topological errors in imported geometry, today we will consider a completely different case study; a sheet metal part that, when imported, will generate topological errors wherever faces are superimposed on each other. This type of error can be revealed by the Import Diagnostics tool, but cannot be healed automatically. In order to solve the topological problems and convert the imported geometry into a SolidWorks Sheet Metal part, we will use various techniques you can learn in the Surface Modeling and Sheet Metal courses, including: copy surface convert a surface body into a solid body convert a solid body to sheet metal find the minimum radius of curvature of given face delete and patch faces create hems Enjoy the video: Note: The model shown…

SolidWorks Tutorial – Import Diagnostics (3) – Troubleshooting and Healing [VIDEO]

This is the third in a series of articles focused on troubleshooting and healing topological errors from geometry imported in SolidWorks. As we discovered in the second article of this series, the Import Diagnostics is a good tool for troubleshooting topological errors. It can also be used for fixing most of them automatically, or semi-automatically (as shown in the first article). I was searching for a great case study of a model with a lot of imported geometry errors that could be healed completely inside the Import Diagnostics dialog box. Fortunately David Bernick posted an excellent example on the SolidWorks Forum. Watch this video in order to fully appreciate the power of the Import Diagnostics tool:

SolidWorks Tutorial: Import Diagnostics (2) – The Manual Healing Technique [VIDEO]

This is the second in a series of articles focused on troubleshooting and healing topological errors from geometry imported in SolidWorks. Yesterday we presented a simple case study of using the Import Diagnostics tool inside SolidWorks for troubleshooting and fixing errors in an imported body. While that workflow did not use the automatic healing options inside the Import Diagnostics tool, it allowed the user to find the parasite face that created the problem and manually remove it, thus healing the solid body. Today we will take a look at a more difficult problem where the topological errors are so complex that neither the automatic, nor the manual tools inside the Import Diagnostics could heal the solid body. That being said, the Import Diagnostics is still very valuable for its troubleshooting functionality. In this case, it will reveal that the problem is created by multiple overlapping faces, as you can see in Fig. 1. For…

SolidWorks Tutorial: Import Diagnostics (1) – “Face Piercing Through Solid” Error [VIDEO]

 This week, we will post a series of articles focused on troubleshooting and healing topological errors from geometry imported in SolidWorks. Two designers of different nationalities can communicate using a lingua franca, a language that is not native to either of them, but which is known (to a certain degree) by both. It is also called a bridge language. Let’s consider a Dutch talking to a Chinese in English. The Dutch will think in his/hers mother tongue and translate those thoughts in English. The Chinese will hear the English words and will translate them in Mandarin or Cantonese in order to process the information in a language that is familiar. How accurate will this communication be? That depends on a lot of factors: How well the Dutch speaks English How well the Chinese understands English If there is a direct translation of the Dutch words and expressions in English If not,…

Using SOLIDWORKS Direct Modeling to modify an imported model without feature history [VIDEO]

Direct Modeling

How can you modify a model without history? Use the SOLIDWORKS direct modeling tools to reverse engineer an existing model. When you need to create tooling or fixtures for your customer parts, it is often necessary to remove all the details that will not be produced by your tooling, or features which are simply not required for modeling your fixture. This process becomes more complicated when the model you receive from your customer has been created with different CAD software. That means you will import only the geometry of the part, without the feature history that created it. Reverse engineer/model an imported part Trying to reverse engineer the part in order to discover how the model has been created is detective work. Less experienced SOLIDWORKS users will try to guess how the part looked early in the modeling process by adding or removing material, using features such as the Extrude-Boss or Extrude-Cut. This can be a very tedious process, with a…

SolidWorks Tutorial: Direct Modeling [VIDEO]

Some people will be shocked by the title of this article. How can you say that SolidWorks can do direct modeling when every operation you perform on the model is documented in the feature tree? Let me start by saying that if the definition of direct modeling includes loosing track of the operations you perform on the affected geometry, then SolidWorks does not have direct modeling capabilities. But if you need to modify existing solid bodies, regardless of how they were created, then I can tell you that SolidWorks has the capabilities that you are looking for! This video present a very good example on how you can perform a complex change affecting a local area of an imported body using SolidWorks. The update is…

Marble Roller Coaster Save Template (Part 3 of many) [VIDEO]

To read the first part of this series of articles, please CLICK HERE. To read the second part of this series of articles, please CLICK HERE. The next step is to create a template or library part that will be used to create all of the roller coaster track segments.  There are two methods for doing this, save as a neutral file format, such as parasolid, or use the save bodies feature.  A part with external references cannot be saved as a template, but a template is easier to use in the future without accidentally changing the master.  I will show the procedure for both, but I am going to use the option of a library part.  The reason for this is to maintain my design intent of being able to change the size of the marble and having the track update appropriately.
