Trimmetry

Trimmetry is a Cinema 4D generator that sweeps a profile along a multi-segment spline and lets you animate the reveal, trimming, scale, and rotation of the resulting polygonal geometry.

The plugin is designed for more than a single spline: it can sort segments, combine them into groups, assign a starting point to each group, and control the animation order.

Quick start

1. Create a Trimmetry object.

2. Place the path spline as the first child.

3. Place the profile spline as the second child.

4. Set GROW = 100% and TRIM = 0%.

5. Choose an appropriate SPLINE_TYPE.

Important

The order of the child objects matters: Path first, then Profile. See Quick start for details.

Guides and reference

• Practical recipes
  • Sequential segment reveal
  • Reveal by length
  • Smooth transitions between segments
  • Growth from the center outward
  • Mirrored sequence
  • Moving visible strip
  • Twisting during the reveal
  • Merging nearby segments
• Troubleshooting
  • Trimmetry creates nothing
  • PATH and PROFILE are set, but there is no result
  • Segments grow in different directions
  • The segment order looks random
  • Too many segments were merged
  • The texture jumps during Grow
  • A seam is visible on a closed path
  • Profile jitter or kinks
• Parameter index
  • Default values
  • Context-dependent parameters
