New Ideas for Filing Corners for Designers

Briefly explain the following ideas:

1: The basic idea is to spread out the fifth-order circle, why is the fifth-order curve, because it can weaken the node to a large extent, so I will not repeat it here;
(Please pay attention to the node position, which still has certain influence. For example, if the import structure software ug SolidWork creo and other small asymmetries will be more obvious, it is difficult to capture the center point, the midpoint quarter point, etc. (of course, if the appearance is not required to be properly stretched for reference), it is necessary to reasonably arrange the manufacturing node position for direct manufacturing.)

2: Rounders and straight lines need natural drop and buffer space, so they need to use the algorithm that comes with the software.

3: The construction method needs to be adjustable, can be constructed into different "rigidity" fillets, and can control roundness;

4: Be sure to be close enough to the circle (of course, some people will say that it is so troublesome. What can you mix? Just pursue the difference. I just need to be very round. Please choose the acceptable method. Xiaobai will not explain it. Some training courses will not explain it here. The fillet optimization function of rhino 8.0 will come soon, so there will be no trouble);





Comprehensive consideration can be achieved by means of regular polygons and straight lines through simple and uniform segmentation (you can imagine spreading the control points of a circle flat, and the circle is just to find several points of equal length):

In order to facilitate drawing and understanding, we use polygon instead of the control points of the editable circle for easy capture. Of course, it is also very simple for you to spread out the editable circle directly like the first picture.

Pay attention to the key steps to select the curve tool order to select the 5th order, from beginning to end of the anchor to the end of the intersection, that is, to get the g3 curve.

The effect of different number of sides on "roundness" and rigidity can be tried.

Right-angle fillet is constructed in the same way.
