Since Unity does not provide a measure tool for 3D Object’s i created one. You can watch the ~35 minutes tutorial about it or just purchase it here.
Unity 5.6+
Description
★ measure 3D Object Sizes
★ measure in centimeter, meter or inch
★ Set Colors based on the Models for better visualization
How To Use
- Drag the Prefab in the Scene
- Position it next to 3D Object / Model you want to measure
- Drag the arrow Left/ Right or Up/Down for vertical measure
- Rotate the tool if needed for vertical measure or diagonals
- Change Show mode, Color, Scale and Rotations directly in the Tool
- Done.
