How Do I Get Bi-Directional Arrows In Visio 2013
Solution 1:
Yea same here but I found it after a while of looking about.
The default styles are loaded based on the kind of project you start with. I started with a UML template so it loads styles based on UML. You can, however, change everything about the object as pictured.
Solution 2:
Insert your arrow as usual and then highlight it.
Once this is completed, navigate to the Home tab > Shape Styles, click the line dropdown and select the type of arrow you need.
