編輯網格
當由掃描儀獲取的數據生成一個網格，所述網格可能不完美的被設計使用。
所生成的網格可能具有缺陷，噪點或需要被填補的孔。
OpticalRevEng Dental 已對每個元件應用於特定的網格生成策略。但是，有可能是他們需要在導出到其他軟件前進一步編輯網格。
在這個網頁中，有一個網格編輯工具，可以找到它的描述在 網格選單或網格工具列.
移除尖角
尖角被定義為是掃描器獲得的三維物體的表面上不實際的的一小部分。
通常，這些尖角由軟體自動生成網格中校正，但如果該網格已經從另一系統導入，一些尖角可能存在。
此工具會自動刪除所有的尖角同時修復網格。

銳化
研磨工具執行兩個動作：它平滑的表面的平面部，並在同時它銳化邊緣，使用兩個參數：
- T [°] : 這個角度識別的優勢是什麼。所有表面具有於T°以下的角度的部分將被銳化。當此值是0，所有的表面進行平滑處理
- 普通迭代: 軟件在表面上進行銳化的次數。數值越高，網格越進行平滑處理和銳化
軟件使用特定的參數自動應用這個工具。在此工具上使用錯誤的參數可能修改物體的形狀和尺寸.
平滑
這個工具是類似於網格銳化，但它適用舒緩於整個表面上，不保留邊緣。
The software applies this tool automatically, using specific parameters. The use of this tool with wrong parameters may modify the shape and the dimension of the objects.
Adv Smoothing
The Advanced Smoothing tool is an improved version of the Smooth tool because it grants more control, more parameters and better results.
The parameters are:
- Iteration
- Number of times the tool will be applied.
- Strenght
- How much the tool can change the object surface. The higher the value the more the mesh is smoothed and sharpened.
- Sensitivity
- How many parts of the surface will be identified as 'Details' (margins, edges). The details parts will be sharpened, but not smoothed.
- Protection
- : How many 'Detail' parts will not be sharpened. The higher the value the less the small details are sharpened.
- Max Deviation
- How much the tool can modify the shape of the mesh. This is the maximum distance every point of the final mesh can have from the original mesh.
- Flip Edges
- If this option is enabled the tool will rearrange the mesh structure to better represent edges.
Decimate
This tool reduces the number of triangles in a mesh, to save more space, trying to preserve as much detail as possible.
On the top is specified the current number of triangles of the selected meshes.
It is possible to insert a percentage of triangles to be kept (For example 50% to halve the mesh size).
It is also possible to establish a tolerance value. If the tolerance is enabled, the software will stop the decimation when this would modify the mesh more than the tolerance parameter.
Just click on Apply to see the result.
Defeature
This tool takes a selection of the mesh and it removes all the details, leaving the surface as plane as possible. It removes holes, spikes, noises. To use this tool:
- Select the area in which it is necessary to remove all the features with the Selection Tools
- Apply the Mesh Defeature
Catenate
This tool can be used only in Free Mode. It takes all the selected meshes and creates a single mesh, merging all of the selected meshes together.
Flip Normals
Every mesh has an inside and an outside. The software gives them two different colors. This tool inverts the inside and the outside of the selected meshes.
Fill All Holes
This is an interactive tool that allows to fill the holes in the currently selected mesh.
This tool can work in 2 different ways
Fill One
In the fill one mode, the software will highlight the hole near the mouse cursor. By clicking with the left mouse button on the highlighted hole it will be filed.
Fill All
In the fill all mode, the software will try to close all the holes. With the Filter By Size function, it is possible to select all the holes below one size and fill them. The selected holes will be highlighted in real time by the sofware.
Curvature Filling
There is an additional option: curvature filling. If this option is enabled, the software will try to close the hole following the curvature of the rest of the surface. If it's disabled, the software will ignore the rest of the surface and close the hole with a straight plane.
Close Denture
When scanning a whole jaw, the base information will not be acquired. This tool has been created to recreate that information. Closing the dunture with the Fill All Holes tool takes too much time and the final result will not be good enough.
With the close denture tool, the mesh will be closed with a perfect plane in a reduced amount of time.
Fix Mesh
Removes all the possible defects and noises of a mesh.
Mesh Offset
This tool creates a bigger/smaller version of the selected mesh. The Offset [mm] parameter allows to select how much the mesh will change.
The three flags (Remesh, Sharpen and Optimize Vertices) have to be checked.
Usually, none of these tools is necessary to work because the strategies already apply a selected sequence of specific tools to each element.
