Hi everyone, recently I want to measure the data of crown length and root length. And I used markupsline tool in Markups Mode. But I can’t find a way to export the desired data (distance in this example). So is there a way to directly export the distance of all markupslines? (I need to measure lots of teeth so it will be loads of work if I need to manually record all the data).

If you save them as in mrk.json format, measurement fields will be saved. You can either programmatically extract that, or use excel as shown in this thread: [Export formats for markups - #13 by lassoan](https://discourse.slicer.org/t/export-formats-for-markups/16278/13)

It works, many thanks!

A few tips that can make your measurement a magnitude faster:

- If you need to measure the same values in many images then pre-create all the markups using [this script](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#pre-populate-the-scene-with-measurements)
- Copy all measurement results (along with input filename and measurement name) into an Excel sheet with a single keyboard shortcut using [this script](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#copy-all-measurements-in-the-scene-to-excel)
- Position the slice view to the correct cross-section much faster: specify the dental arch using a markups curve node, then reslice along that curve using “Cross-section analysis module” (in SlicerVMTK extension) or straighten the arch using “Curved planar reformat module” (in Sandbox extension).
- Adjust the cross-section by rotating slice intersections by [rotating slice intersections](https://slicer.readthedocs.io/en/latest/user_guide/user_interface.html#slice-views)

See this video of how to set up keyboard shortcuts for defining measurements and copy them directly to Excel:
