I'm a math teacher. I like to use Blender to demonstrate some ideas when we talk about geometry in 3 dimensions, so I display it on our projector and the class will work together to edit some basic shapes. I've changed the size of vertices so they are bigger and easier to see, but I haven't found a way to increase the size of edges. Is there an option to do this?

Unfortunately, you cannot. You can edit vertex and face dot size but not edge thickness.

I defer to the other answer for the (easy?) workaround.


I think I understand your question.

Don't use wireframe mode. Instead, use solid mode and use the wireframe modifier. Here is a quick recording using the mathematical object hexagonalmonkeyprismoidalsphere:enter image description here

  • $\begingroup$ The wireframe modifier is a nice idea, but I want to still be able to see the solid geometry. I was really just hoping to be able to change how edges appear so they're easier to see on a projected screen. $\endgroup$

  • $\begingroup$ @Jason You can uncheck the "Replace Original" button, and then you can change the material index of the wireframe $\endgroup$

  • $\begingroup$ Only one downside I see here is that it will only work with objects which have faces.... I use wireframe meshes also for similar things and often I need to have edges only... $\endgroup$ Aug 8 '19 at 9:28
