Pre-Processing for Polygon Reduction

Pre-Processing for Polygon Reduction

Pre-processing for polygon reduction is possible using polygon facet resolution settings. Since the Polygon Reduction tool starts with a default facet density, it can sometimes be useful to adjust that pre-set facet density to a higher value. More information about the Polygon Reduction tool can be found here. Change Facet Resolution Starting with a sample CAD component, you can select the model with the Single Select tool, or just “Select All”, and right click to get the Change Facet Resolution options (see figure 1): Normal: The lowest resolution option, approximately 27 segments on a cylinder or hole. Medium High: Slightly higher than normal,...
Do Your Translations Look Like This?

Do Your Translations Look Like This?

Do your translations look like this? If so, you’ve got problems! This is the actual result of a translation by a software solution we will not name here – but you can imagine how dismayed the user was when they saw this output! The user contacted us and we set them up with a copy of TransMagic to solve their problem right away. Mis-translations can take many forms, from missing geometry (usually the most complex, organic geometry is missing, and prismatic geometry is retained), to missing details and PMI, to geometry that is there, however unusable; the screenshot above is simply the most outlandish and entertaining case of unusable geometry...
Calculate Edge Length

Calculate Edge Length

All core TransMagic products allow you to calculate mass properties (weight, volume, centriod), surface area, create a bounding box, measure and add dimensions – but have you ever needed to calculate the length of straight or curved edges? You might need to know edge length in order to estimate a particular machining operation, for example breaking edges. Getting that value is not intuitive, so we thought we’d show you how here. It’s basically a two-step process: Step 1. Select the edges you want to get the length of. As you can see in this first screenshot at right, we have a solid model that has had several edges selected (highlighted in...
Can you find the errors in this CAD model?

Can you find the errors in this CAD model?

Can you find the errors in this CAD model? This ACIS compressor looks fine to the naked eye; but what problems lurk beneath the surface? We can run the Auto Repair Wizard to find out; find this tool on the Home toolbar and click it. Normally, we’d just run the Auto Repair Wizard and keep clicking “OK” to complete the repair process; doing so, we’d have this file repaired in about three seconds. This time, though, let’s exit the ARW before it has a chance to heal the model; see this step in the upper left of figure 1, at right. The ARW analyzes the repair needs and suggests a course of action, highlighting areas of concern on the...

Protected: Can CAD File Formats Impact Job Quality?

Can CAD file formats impact job quality? Does it really matter which CAD formats you use internally, or with customers and suppliers? With seven major manufacturing CAD systems, as well as various geometric modeling kernels and neutral CAD files, we’re certainly living in a multicad world. How do you make sense of all the different CAD file formats available, and how do you decide which CAD format is best for different tasks? Depending on how you break it down, TransMagic can currently read or write 29 different major CAD or polygonal file formats (To download the main image on this page as a PDF, click here). This article will look at the costs of using...
Automated CAD Translation

Automated CAD Translation

The fastest way to translate lots of files is through automated CAD translation, a type of batch processing; through this technique, hundreds or even thousands of files can be translated into the format of your choice at one time, saving you and your department valuable design and engineering time. This process has two key advantages: Automation The files can all be queued up at one time by the user, eliminating the time-consuming process of using the mouse and keyboard to individually locate and open each file, and eliminating the process of saving each file to the desired format. Direct Translation A great deal of time is wasted each day by CAD users waiting...
