How to clear values in measurelt (Toolpanel>display)) I am using helplines to determine the outer angles of the cylinder. I need these angles to align the cubes exactly to the cylindersides. Measurelt puts values on top of each other however, making them unreadable (see image) Is there a way to clear these values (then I can also get rid of the light blue angle font which is hardly readable)? 
And if there is an easier way to align these cubes tot the cylinder I would like to hear that too. I know I can duplicate the sides of the cylinder and make them into cubes with the right angle, but that is not what I want.
Perhaps a quicker way to do this particular job is with an array?


Create your 14-sided cylinder at the origin.
Create your cube at the origin
In Edit mode move/scale the mesh of your cube to  your desired position with respect to one of the the cylinder's faces (probably down X in your example).. leaving its origin behind.
Create an empty at the origin
Assign an Array modifier to the cube with 'Object Offset' and the empty as target
Rotate the empty in Z, entering '360/14' as the angle
set the array count to 14


You can then select the empty and the cube array together, and translate them in Z to adjust the vertical position of the cubes. and if you edit the cube, all the arrayed instances of it will be edited too.

If/when you need the cubes to be independent, you can apply the modifier.
