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...
Model Repair By Color?

Model Repair By Color?

Depending on how a part was modeled, designers or engineers can sometimes create solid bodies that share the same plane; normally, this will cause an error, as the CAD system sees two bodies using the same, or ‘duplicate’ surface. However, if the solid bodies are already in different colors, TransMagic can run the repair on each differently colored solid body separately, thus seeing no shared or ‘duplicate’ surfaces, enabling a multibody solid model to be generated. Other Color-Related Tools Other ‘color’ tools include ‘Set Color Filter’ and ‘Clear Color Filter’ on the home menu, and ‘Change...

A Classic CAD Repair Scenario

A Classic CAD Repair Scenario

A Classic CAD Repair Scenario Imagine that you have a part or assembly that is difficult to repair; what you’re after is a watertight solid. Here’s one approach that demonstrates the use of different selection modes in the context of a repair situation. The main purpose of this process is to delete any construction or ‘scrap’ geometry that may be interfering with the repair process; such ‘scrap’ has been artificially created for this example, but it’s common enough in real-world examples. TransMagic has other techniques and tools, but this is one of the more common and effective. We’ve broken this process down...
Selection Options

Selection Options

Choosing Your Selection Options At first glance, it looks as if there are only four geometry selection options in TransMagic – Single Select, denoted by an arrow, Window Select, denoted by a rectangle, Select All Entities and Deselect All Entities (see screenshot at right). However, there is a drop down arrow to the right of the top two buttons, which allows you to filter out entities. Selection filters can be applied in the following ways. Dynamic Selection Assembly Level Selection Body Level Selection Face Level Selection Edge Level Selection Vertex Level Selection PMI Level Selection Select Only Solid Bodies Select Only Surface Bodies Select Only Wire...
Six Reasons to Avoid IGES Files

Six Reasons to Avoid IGES Files

The IGES file has been the bane of the CAD/CAM/CAE world for years, yet it remains with us to this day. This article defines some of the problems with the IGES format. A follow-up article will propose some alternative formats which are better equipped to handle most 3D design data needs. IGES stands for Initial Graphics Exchange Specification; it was first published in 1980 as a vendor-neutral file format to facilitate the transfer of information among different CAD systems, and though use has dropped in the last decade, IGES is still a widely used format in the manufacturing world. In fact, the 2013 3D Collaboration and Interoperability Report published by...
