Arrow Head in Graphics is extremely large

Questions
1

When I use the command “Graphics3D[Arrow[{{1, 1, 2}, {2, 2, 8}}]]” embedded at the end of a Show[] command, the arrow head seems to overwhelm the rest of the plot - see last graphic at end of notebook. Actually, I have more examples that are even more pronounced if you would like to see them.

I have used this command for some time without any problem. Does anyone have an idea of the cause?

Thanks,

Mitch Sandlin

What notebook?

The one attached below - GradWork01.

Not sure what happened to the one that I attached earlier.

Thanks so much for reviewing this.

Hi Mitchell,

Try this

Graphics3D[{Arrowheads[.01], Arrow[{{1, 1, 2}, {2, 2, 8}}]}]
