Break bends are a kind of origami fold that can be utilized to create complicated and attention-grabbing shapes. They’re fashioned by folding a bit of paper backwards and forwards alongside a collection of creases, after which collapsing the creases collectively to create a pointy bend. Break bends can be utilized to create quite a lot of totally different shapes, from easy angles to complicated curves. They’re additionally typically used along with different origami folds to create extra elaborate fashions.
To make a break bend, begin by folding a bit of paper in half alongside the specified crease. Then, open up the paper and fold it in half once more alongside the identical crease. Repeat this course of till you could have made a complete of 4 folds alongside the identical crease. After you have made 4 folds, open up the paper and fold it in half alongside the other crease. This may create a collection of creases that intersect at a proper angle.
Subsequent, collapse the creases collectively to create a pointy bend. To do that, maintain the paper in a single hand with the creases going through up. Then, use your different hand to push down on the middle of the creases till they collapse collectively. As soon as the creases have collapsed, you should have created a break bend. Break bends can be utilized to create quite a lot of totally different shapes, from easy angles to complicated curves. They’re additionally typically used along with different origami folds to create extra elaborate fashions.
Deciding on the Edge or Floor
Previous to executing the Break Bend command in Rhino, it’s crucial to pick the specified edge or floor that you just goal to switch. This choice performs a vital position in figuring out the orientation and place of the bend created. This is an in depth information on choosing edges or surfaces for Break Bend:
Edge Choice
1. **Determine the Edge:** Begin by figuring out the particular edge on the article that you just wish to bend. It may very well be a straight line, a curve, or a polyline.
2. **Choose the Edge:** After you have recognized the sting, choose it by clicking on it with the mouse. The chosen edge shall be highlighted in a distinct coloration, usually orange in Rhino.
3. **A number of Edge Choice:** When you want to bend a number of edges concurrently, maintain down the “Shift” key whereas clicking on every edge. This may can help you choose and bend a number of edges in a single go.
| Edge Choice Methodology | Description |

Then, click on on every subsequent level of your curve. Double-click on the ultimate level to shut the curve.
After you have created a baseline curve, you possibly can proceed to the subsequent step, which is defining the break factors.
Further Particulars for Utilizing the Polyline Device
When utilizing the Polyline device to create a baseline curve, there are a couple of extra choices that you need to use to manage the form of your curve:
- Section mode: You’ll be able to select between linear segments or bezier segments. Linear segments create straight strains between factors, whereas bezier segments create easy curves.
- Match mode: You’ll be able to select between easy match or tangent match. Easy match creates a curve that’s easy and steady, whereas tangent match creates a curve that’s tangent to the factors you choose.
- Variety of segments: You’ll be able to specify the variety of segments that you really want your curve to have. This may have an effect on the smoothness and complexity of your curve.
By experimenting with these choices, you possibly can create a baseline curve that’s precisely the form you need.
Aligning the Baseline Curve
The third step entails aligning the baseline curve to the specified angle. This ensures that the break bend easily transitions from the unique curve. This is an in depth breakdown of this step:
### 3.1: Choose the Baseline Curve
Start by choosing the baseline curve that can type the premise for the break bend. This curve needs to be linked to the unique curve on the level the place the bend is meant.

| 4T | Bend radius is 4 occasions the thickness of the sheet steel |
By adjusting the bend radius, you possibly can management the tightness or curvature of the bend to realize the specified form and performance.
Including Transition Curves
To realize an aesthetically pleasing and structurally sound break bend, it is essential to include transition curves. These curves smoothen the transition between the straight segments and the bend, making a gradual change in course.
Step 1: Determine the Break Factors
Find the factors the place the straight segments intersect and the place the bend begins and ends. These factors will function the anchors for the transition curves.
Step 2: Draw the Transition Curves
Use the “Curve” device in Rhino to attract two curves that join the straight segments and the bend factors. These curves needs to be easy and tangent to the straight segments and the bend.
Step 3: Alter the Curvature
Modify the curvature of the transition curves by adjusting the management factors. Growing the gap from the anchor factors will create a extra extreme curvature, whereas lowering the gap will produce a flatter curve.
Step 4: Examine the Continuity
Make sure that the transition curves are C1 steady. Which means that the curves have the identical first spinoff on the transition factors, making a easy transition in each course and curvature.
Step 5: Controlling the Transition Size and Form
The size and form of the transition curves play a crucial position within the last look of the break bend. This is an in depth breakdown of the elements to contemplate:
| Issue | Influence |
|---|---|
| Size of curve | Controls the gap over which the transition happens. Longer curves lead to a extra gradual transition. |
| Radius of curvature | Determines the sharpness of the transition. Bigger radii create shallower curves, whereas smaller radii produce sharper curves. |
| Place of management factors | Impacts the form of the curve. Shifting the management factors farther from the anchor factors will increase the curvature initially and finish of the transition. |
Experiment with these elements to realize the specified transition impact on your break bend.
