When the beginner is reversed, there is often a “crease†between the two faces, which is mainly caused by the fact that the two faces are not tangent. Solving this problem can be solved by adjusting the endpoint of the Though curve mesh curve to the corresponding curve in the other face, plus the Thaw curve mesh tangent option. Only the curve is tangent to ensure that the surface is tangent. Previous page C7/C9 Light Bulb LED Filament COB technology provides amazing illumination. The LED

In addition, sometimes it is more convenient to use a point cloud directly from a single, flat surface. However, those surfaces with large changes in the radius of curvature are not applicable, and the errors in the construction of the surface are large. Sometimes the gap between the face and the face is bridged to ensure a smooth transition of the surface.
In the process of building a surface, sometimes you need to add some lines for the facet. Connections and facets often alternate. After the surface is built, it is necessary to check the error of the surface. Generally, the error from the point to the surface is measured, and the surface with high appearance is also checked for the smoothness of the surface. When a surface is not smooth, you can find some Sections of the surface, adjust these Sections to make them smooth, and then use these Sections to re-conform the surface, the effect will be better, which is a commonly used method.
The facets should also be kept simple. Face should be done as much as possible, the number of sheets is small, not too broken, which is beneficial to add some features such as rounded corners, slopes, thickening, etc., and is also conducive to the next programming process, the calculation of the tool path will be reduced, NC The file is also small.
Fourth, the body
When the outer surface is complete, the next step is to build a solid model. When the model is simple and the quality of the outer surface is good, the solidification can be established by the stitching thickening command. However, in most cases, it cannot be thickened, so only the outer surface of the offset can be used. Use the Offset command to select multiple faces at the same time or select them all with the window, which will improve efficiency. For surfaces that cannot be offset, learn to analyze the cause. One possibility is that the curvature of the surface itself is too large, and the offset will self-intersect, causing the Offset to fail (some software algorithms are different from this algorithm, such as the Rhinoceros can offset those surfaces that will produce self-intersecting), such as small rounded corners. Another possibility is that the quality of the offset surface is not good, and there are local ripples. In this case, only the surface can be modified and then Offset; some surfaces look good, but they cannot be Offset. This situation can be achieved by using Extract Geometry into a B surface and then Offset, which will basically succeed. Some of the offset surfaces need to be cut, some need to be complemented, and the inner surface is constructed by various surface editing methods, and then the inner and outer surfaces are stitched into a solid. Finally, the product structure design, such as ribs, mounting holes, etc.
