Choose your path

Start from the task, not the category tree

Pick a starting point based on the work in front of you. Each tool page is built around the result, with the controls close to the output.

Need a quick number?

Use one calculator for common percentage questions, from discounts and ratios to reverse percentage work.

Calculate percentages

Designing a Minecraft build?

Move from rough build idea to block layout with previews, dimensions, and shape-specific controls.

Generate shapes

Bringing in a 3D model?

Turn a 3D model into block coordinates when a simple shape generator is not enough.

Convert a model

Balancing a factory?

Trace what your Satisfactory factory needs before you place another line of machines.

Plan production
