Geomagic Essentials works as a bridge between mesh data to CAD. In addition to mesh optimization techniques like hole filling and mesh size reduction, it can also extract features for use as a point of reference and perform autosurfacing on intricate designs. The features and nurbsurfaces can then be saved in a CAD-readable format. This article provides a helpful Q&A on Geomagic Essentials. You may have a better understanding of the fundamentals after reading it.

 

 

 

Functions

 

 

Q: How to move scans in Geomagic Essentials? 

---

 

Press and hold alt + scroller, then you are able to move the model.

 

 

 

Q: How to merge two different meshes together?

---

 

There are several ways to merge 2 meshes.

1. Global registration
2. Manual registration
3. Align word
4. Boolean

 

 

 

Q: How to improve the 3D model quality through post-processing?

---

 

One way to improve the quality of a 3D model through post-processing is remesh or refine after scanning.

 

 

 

Q: At the hole-filling function, is there a way to smooth the contour of the hole?

---

 

Generally, Geomagic Essentials has powerful hole-filling and editing capabilities. Smooth the contour of the hole can be achieved by using the relax boundary function (scan->modify->relax boundary).

 

 

 

Q: Can we fill all holes except one we wish to keep?

---

 

Hold ctrl and click left mouse button to unselect

 

 

 

Q: The patch will become very complex if our scan data has rough edges. Can we simplify/straighten the edge, so the patchwork is more simplified?

---

 

You could try the Boundaries->Edit Boundary feature. If you reduce the control point quantity, you will have a much smoother edge.

 

 

 

Q: Can Geomagic Essentials handle single surface thicken?

---

 

Yes. Select the specific surface which is isolated, then shell-thicken.

 

 

 

Q: Can I export a single surface for half ball shape (no rough edges, e.g bra cup)?

---

 

Yes. Just use the Auto-Surfacing function.

 

 

 

Q: After auto surface, there will be a lot of small surfaces when we check using another CAD software. Can we eliminate this and export it as a single surface?

---

 

Use the manifold function to delete unwanted small parts.

 

 

 

Q: Regarding the exportation and auto surface, is there no way to use the boundaries or the curves/free curves as a guide/sketch on a different CAD besides Solid Edge?

---

 

Any CAD software can import and open STP, IGES, like Solidworks.

 

 

 

Q: How to create functional parts? For example, accurate hole dimensions and how to correct grid errors after the Auto Surface function is used.

---

 

The position accuracy depends on the mesh. Complete and high-accuracy mesh results can provide a better reference, or if you know the position relations of each part, you can draw them in the CAD software.

 

 

 

Q: How do I transfer the file to the CAD software so that the data I extracted stays arranged? Not all the details move to the other software.

---

 

Tick all references and features you created, and save as single file.

 

 

 

Q: How to extract clean polylines for laser cutting?

---

 

It is possible to draw polylines in Geomagic Essentials, but everything done in it is based on eye observation. Lines will not have dimension bounding, we would like to suggest doing this in CAD software, like Solid Edge.

 

 

 

Q: How to bring it into Solid Edge?

---

 

Save as IGES and import to Solid Edge. You check the detailed steps here.

 

 

 

Q: Is there a modeling history in Geomagic Essentials?

---

 

Currently not support editing history. Every change before clicking apply can go back. After clicking apply, the results are saved and can not be reversed.

 

 

 

 

Others

 

 

Q: Can I continue to update the software after purchase the RED bundle? where can I download the new version?

---

 

Yes you can. The latest version is V2.0.2.3001. Remember to deactivate the old version before activating the newer. Please download from: passport.shining3d.com.

 

 

 

Q: Is it possible to use Gemagic Essentials on 2 different computers?

---

 

One Geomagic Essentials license code can only activate one computer. If you need to switch the computer, remember to deactivate the license code on the previous computer and then activate it on another one.

 

 

 

Q: What is the minimum requirements hardware for the Geomagic Essentials?

---

 

Please refer to the table below.

 

In this article, we will show you how to fill holes in Geomagic Essentials.

EinScan is equipped with the scanning software EXScan which also has a hole filling function. The automatic hole filling can fill holes with a perimeter smaller than the value you set, while the manual hole filling function can only detect holes with closed borders and can fill them by simply clicking on the edges of the holes. However, if the object is complex or has more features. It is better to use Geomagic Essentials so that the filled part can better fit the surface.

Hole Filling Function in EXScan

Here are the feature points of Geomagic Essentials about filling holes:

1. Mesh Doctor function

This function in Geomagic Essentials can analyze and remove defects, for example, self-intersections, highly creased edges, spikes.

2. Fill techniques

Same as the EXScan software, Geomagic Essentials also provide Curvature, Tangent, and Flat, for different surfaces we can select different fill techniques.

3. Hole filling modes

Compared to EXScan software, Geomagic Essential has more modes for hole filling, such as complete, partial, and bridge. Below are the explanations of these modes:

● Complete means that it will fill the hole completely, it fills a closed boundary.

● And partial means that the hole can be separated into two parts, it fills between two selected points and an included boundary, so only one part will be filled.

● Bridge fills from selected triangles edges to selected triangle edges. This mode is very useful when you need to fill a hole that has like stair shape, two faces are not connected in a smooth phase.

In each case, you need to choose different combinations of fill techniques and fill modes to best fit the original shape of the object.

Comparison of data before and after filling the hole

Overall, geomagic essentials offers a very powerful hole-filling feature and you can see that the result fits the shape of the object itself very well. Hole filling is the most important step in the 3D scan data post-processing process.

Also, for a better user experience, we offer an all-in-one solution for reverse engineering in industrial applications, EinScan Reverse Engineering Design (R.E.D) Bundle, for experienced users. This bundle includes:

1) 1 unit of EinScan 3D scanner
