I recently realized that blender have a "Ruler/Protractor" tool for precise measurements. Is there a way to make those measurements appear on final renders? (By the way, is there a way to customize the transparency of those measurement value displays?)

Thanks in advance for replies.

(I am using cycle for render, but it is fine if I have to use Blender Internal for the measurements to appear)

  • $\begingroup$ I don't think this is possible. The only way I can think of is by taking a screenshot and compositing it on somehow.. You might just be better off modeling your own ruler/protractor using the snapping tools (you would have to add the numbers manually). $\endgroup$

  • $\begingroup$ Well, taking screenshot have the limit of resolution. Maybe the solution is really manually modelling the measurements. Is it possible that there is some sort of python addin that can achieve this? $\endgroup$ Jan 22, 2014 at 10:00

A small trick is to temporarily increase the DPI value (located in User Preferences > System (maximum to 144), then maximize the 3D window and capture the screen. (Maximize the desktop resolution before that if possible).

enter image description here

However, you are right about the limit of resolution, so this is the last choice, I guess, unless capturing several parts and tiling them manually.

    $\begingroup$ @AnsonSavage, AFAIK it isn't supported. Anway you may want to try some addons such as MeasureIt. $\endgroup$ Dec 2, 2016 at 6:45
