I am not sure about inputting exact co-ordinates as you draw. However, you can right click on any point to bring up the Vertex Editor and then manually change the X and Y co-ordinates like that. Alternatively, you could import a .csv file containing all of your co-ordinates and generate geometry out of that. This would require using the New Layer > Delimited Text Layer function.
I am not sure with the default tools, not like in other CAD software, at least. But to create a line with a specific length, you can do it through creating points and then use the vertex editor to give them specific co-ordinates. You must create a point-style layer, turn on editing, create the points (place them wherever), and then right-click on one point to bring up the vertex editor panel. If you are using a CRS with metres as the unit, you would then change the co-ordinates of one of the points to be X metres away from the other. You'd then draw a line snapping to those points with your main lines layer. It's a bit round-about but that's one way to do it. The other would be to draw in Rhino, AutoCAD, or VectorWorks and export as a DXF and import directly!
Thanks for the clear explanation. Appreciated from a QGIS learner👍👍
Thanks for the clear explanation !
Brilliant clear explanation. Thank you.
Thanks for the good demo. How do you edit existing polygon?
Legend mate - very clear
Thanks,
It would be nice to add how to place your line/polygone at specific points (e.g how to create a line from coordinate 1 to coordinate 2)

Thank you this was helpful!! Is there a way to make the lines a specific length??

Cheers m8 I'll check it out.
How do I do like a free hand editing?
It won't let me save rectangles?
Check your projection system. Some geometry can misbehave if you have more complicated CRSs and the new layer doesn't share the CRS.
