Quick start

Minimal scene

1. Create a spline to use as the path.

2. Create a small Circle, Rectangle, or a custom profile spline.

3. Create a Trimmetry object.

4. Drag Path under Trimmetry as the first child.

5. Drag Profile there as the second child.

The hierarchy should look like this:

Trimmetry
├── Path
└── Profile

Warning

In the tested build, the generator reads the first and second child objects directly. The PATH and PROFILE fields are visible in the interface, but use the hierarchy above for reliable operation.

Initial settings

For your first test, use:

Parameter	Value	Result
GROW	100%	All available geometry is visible.
TRIM	0%	The beginning of the range is not trimmed.
SYMMETRY	ON	Growth proceeds from the Anchor in both directions.
SPLINE_TYPE	OPEN PROPORTIONAL	A convenient mode for your first open path.
SPEED_MOD	TIME	All groups receive equal time.

First animation

1. At frame zero, set GROW = 0% and create a keyframe.

2. At the last frame, set GROW = 100% and create a keyframe.

3. If there are multiple segments, adjust OVERLAP.

4. If necessary, change their order in Segment Sort.

5. Set the reveal point in Anchor Sort.

Path and Profile

Path

May contain multiple segments. The number of points in each segment determines the ring density and therefore the level of detail in the result.

Profile

Must contain at least two points. A closed Profile creates a closed cross-section; an open Profile creates a strip.
