A ruler would be useful for me as well. I struggle a bit when preparing simple technical drawings for my classes

Exactly! I just don't get why developers of GoodNotes didn't consider adding this tool in the first place. It's just ridiculous and doesn't make sense to use recognition tool when we have something more precise: a ruler! Why in the world!

For tasks such as note takings that require PRECISION, we need a ruler.

Have you ever taken HCI, UX/UI class in undergrad, bro?

This shouldn't be too hard to add. Now that I need to be able to graph, I'm having difficulties doing it with the existing shape tool in GoodNotes 5. Even if it were just the ruler, I think a lot of people who use GoodNotes on a regular basis would be very happy.

Having a pencil and a ruler would be great for me, for example to draw graphs.

to improve accuracy when drawing

Allow option to make the ruler rotate in set increments and adjustable by the user.

Allow option to show MM and CM sizes on the ruler (not just line markings) and another option to lock ruler size so that it scales when zooming in and out.

Allow option on protractor to show degrees (not just line markings).

Allow option on both to make the pen ink magnetic to the edge of the tool being used.

Maybe like in ZoomNotes.

I'm using GoodNotes for my studies in electrical engineering.
A square and ruler would be perfect for my technical drawings!
Then I can draw vector diagrams better and use their data in the right scale for example!

a ruler would be great both to draw as a line AND as an indication where you are on the page.
I project my iPad on a big screen. Instead of using different pages, it is great to draw in such a way that at the end there is an overview on one page.

so helplines (maybe also dynamic) in addition to the ruler would do wonders. Now I draw lines myself and erase them later to make better orientation, only sometimes you erase more then you want.
Thanks!

And also be able to draw curves with the pencil

A ruler, protractor (to measure angles), and such would be extremely useful for math-related classes.

I'm also interested in all with University. I'm a Engineering Student, so if you had news about stuff for school send me please jeremytrindade@ufp.edu.pt

I would love it if a ruler were available. So you could make exact connections between points. Sketches are even more accurate

I use this app for engineering in college but without a ruler and set of squares, I can’t do the things I need

Agree with all these suggestions. Ruler, protractor, set squares, grid overlay that can be turned on and off, snap to grid, snap to point, dotted lines, arrows.

And a pair of compasses would be usefull too.

yes please!!

Ruler pls :)

There must be essential tools for doing geometry which will help in making precise lines, angles.

Yes! I need this feature. I’m a engineering student and I save a lot of paper by working in this app. We draw a lot in Smith charts and is great to be able to insert a Smith chart as a new page BUT we need a ruler :D
