Dealing with Duplicate Surfaces

Dealing with Duplicate Surfaces

Duplicate Surfaces are a Problem Certain processes can cause CAD models to have duplicate surfaces or faces. This can create problems when it comes time to translate, repair or otherwise use the model downstream; it’s hard to stitch two sets of surfaces into a watertight solid, and without a watertight solid, almost all downstream applications, from feature recognition to machining to analysis will suffer. How do you know if you are dealing with a duplicate surface? One giveaway is the ‘venetian blinds’ effect you can see in figure 1, which is a result of two nearly coincident surfaces vying with each other to be displayed. Another clue can...

Dude, Where’s My CAD Data? Part 3

Last week’s article on missing CAD data discussed how to know what version of a CAD file you have, and how to know if your translation software is out of date.   This week’s post will look at some further issues that can arise; entities such as points can be turned off, you may have saved to the wrong version for the destination software, you may need to import data, you may have lost faces during translation, and you may be dealing with a suppressed part.   This is our final article on the subject for now – but knowing the insidious nature of missing data, we fully expect to have more to say on the subject in the near future!   Check out...

Dude, where’s my CAD Data? Part 1

It’s not that uncommon an experience that we open a CAD part or assembly file, only to find that part or all of the data appears to be missing. What could be the reason for it, and what can we do about it? This article, and the followup article next week, will attempt to cover some of the causes and solutions to missing CAD data. If you want to see a video that covers missing CAD data, click on the link below. Note that in TransMagic R12 there is now an automatic missing files alert that comes up if you load an assembly and TransMagic cannot find missing parts; this is in addition to the TransMagic log file which also contains missing part information....

TransMagic Product Wizard

As of April, the TransMagic Product Wizard was launched; this is a selection tool to help you figure out which TransMagic products are a good fit for you needs. The product wizard is available on the products page here. Simply select the radio buttons for the functionality you need, and the suggested core product and add-ons will automatically populate the area below. Want to try another set of options? Just check and uncheck radio buttons at will and the suggested configuration will change dynamically. Here’s a brief summary of the TransMagic Product Wizard View The View tools are included in all TransMagic core products. View All Major 3D Formats: At...
Do You Have the Magic Button?

Do You Have the Magic Button?

‘Any sufficiently advanced technology is indistinguishable from magic’ – Arthur C. Clark The Magic Button The Magic Button is what you need at any given time; when you have a bad CAD model, the magic button is the Auto Repair button. When you have a CAD file you need to view, the magic button is the Open button. When you have a format you need to translate to, the magic button is the Save As button. And when you have two files you need to compare, the magic button is the Analyze button. It’s often a single button because that’s how TransMagic was developed, with simplicity in mind; sure, there are settings you can adjust if you...
Tips for Working with Large CAD Files

Tips for Working with Large CAD Files

Large CAD files are all too common for a large percentage of designers and engineers. We typically receive a few calls each week from customers and prospects who are wrestling with CAD parts and assemblies that are anywhere from 50MB to 1.5GB. Files this large can tax even the fastest machines and throw a wrench into your work schedule. What can you do about it? Make Sure You Have Enough RAM: The main requirement to work with large 3D CAD models and assemblies is available RAM in your setup. The recommended minimum RAM required to run TransMagic is 16MB. That should cover you for quite large parts or assemblies. For any CAD file except JT (JT is addressed...
