Overview

The Fold function is to set the angle of inner curves for the folding effect.

Location

Inner Curve > UI Panel > Properties > Inner Curve Properties > Fold

Operation Method

1. Select the inner curve for folding in Curves/Points Selection Mode.
2. Enter your desired angle value via UI Panel> Properties> Inner Curve Properties> Fold.
3. Enable **the Fold in 3D option to fold in 3D view.
4. Adjust the Roundness and Smoothing options to make the folded line looks smoother.
5. You can check whether the angle was applied properly with the color of the inner curve in 2D view.
6. Simulate to check whether inner curves with angles are folded in the 3D view.

Components

Angle

Angle is a function for setting the folding angle by adjusting the value.

The basic flat plane is set at 180°. A smaller angle will lead to the surface folding inwards, and a larger angle will lead to the surface folding outwards.

• Blue: 180º (flat plane)
• Yellow: <180º (folds inwards)
• Violet: >180º (folds outwards)

Roundness

Roundness is a function for setting the roundness of angles.

A lower value will have sharper folds, and a higher value will have rounder folds.

For example, with a 5 cm roundness value, a 2.5 cm offset is given to each side to create a round curve. This function is useful to softly fold neck collars.

Strength

Strength is a function for setting the strength of folds.

The fold line is less affected by external factors and physical properties and keeps its shape well.

Fold in 3D

Fold in 3D is a function for folding and placing in the 3D view according to the line where the angle was set.

Side Change

Side Change is a function for changing sides when applying the Fold in 3D.

Smoothing

Smoothing is an option where smoothing can be applied to inner curves in the 3D view.

Enabling smoothing will show smoothly folded inner curves.
