Detecting and Correcting Non-Manifold Geometry

Detecting and Correcting Non-Manifold Geometry

The MagicHeal Add-On for TransMagic now includes a powerful set of tools that help you with detecting and correcting non-manifold geometry. This is important because failing to detect non-manifold geometry can lead to problems downstream, when you are trying to use that geometry in a CAD system (such as SOLIDWORKS or Solid Edge) that does not support non-manifold geometry. What does Non-Manifold mean? Manifold is a geometric topology term that means: To allow disjoint lumps to exist in a single logical body. Non-Manifold then means: All disjoint lumps must be their own logical body. See a more detailed description of non-manifold geometry in this article. Two...
Repair By Color

Repair By Color

What in the world is Repair By Color, and how could that possibly be useful? During Lite Repair, TransMagic attempts to stitch together surfaces that are near enough to one another to constitute an independent body; if two faces share the same plane, the error “Coincident Faces” can occur. The figure at right is one such example; running Lite Repair on this geometry will lead to the Coincident Faces error. This error is not uncommon since the CAD modeling process often designates the same plane for neighboring parts and bodies. This is possible because the environment is virtual and not real-world. In the real world, there is usually a slight...
Machine Gun Surface

Machine Gun Surface

Machine Gun Surface replaces missing faces and surfaces until the CAD model is watertight. The sequence is simple; just click the Machine Gun Surface button (found on the MagicHeal toolbar). In the example in the image at right, Machine Gun Surface replaced thirteen surfaces in less than 10 seconds. The last step, if you are satisfied that the model looks good, is to select all the geometry and run Lite Repair (from the Home toolbar) to stitch the newly added surfaces to the model. Machine Gun Surface is an automatic version of the Find Next & Cover feature found in Advanced Repair, part of the MagicHeal add-on. The benefit of Machine Gun Surface is that,...
Advanced Repair Tools

Advanced Repair Tools

Advanced Repair Tools can solve some of the thornier problems of CAD repair, often in just seconds. In the process of translating from one format or CAD system to another, it is not uncommon that some geometry is lost. If you suspect that poor translation is your problem, consider trying TransMagic as your translation solution; however, sometimes the translation is done and you have no other recourse than to repair the model. Advanced Repair Tools are included with TransMagic’s MagicHeal add-on, and allow you to address many of these cases and cover missing surfaces in a variety of ways. The key features of Advanced Repair Tools are Cover Circuit, Cover...
Full Repair Recaptures Design Intent

Full Repair Recaptures Design Intent

When you model a box, you expect the faces to meet at an edge, and when you create a fillet, you expect the surfaces to be tangent. Poor translations can sometimes lead to gaps between surfaces and discontinuities in curved surfaces. That’s where TransMagic’s Full Repair comes in. Full Repair is one part of the MagicHeal add-on; it works to recapture the designer’s original intent for each model. Extending and Reintersecting Edge Geometry As Figure 1 illustrates, Full Repair enables you to extend and reintersect surface edges to create a cohesive watertight solid (figure exaggerated to illustrate process). Gaps between surfaces can hinder...
CAD Repair in Seconds Flat

CAD Repair in Seconds Flat

All core TransMagic products come with the Auto Repair Wizard and Lite Repair, giving you CAD repair in seconds flat. By default, every model that is opened is evaluated by the Auto Repair Wizard (ARW) to see if it is a watertight solid, and if there are any underlying issues. In the before-and-after image at right, the ‘before’ image has different default colors for each face or surface; this is an indication that you are dealing with an group of surfaces rather than a watertight solid model. In the ‘after’ image, the color of the model is uniform, indicating that the model is a cohesive solid. Based on what the ARW finds, it will...
