Hi All, newby here. I'm following the "Beginners Guide to Solidworks" tutorial on Solidworks Youtube channel, to draw a pair of plier. In video2, (Sketch and Extrude) at 5:09, after I make the 3 point arc,  I cannot get the smart dimension to work for the life of me. I click on smart dimension from the menu, the cursor changes to the dimension, but I cannot select any points on the arc. Only point I can select is beginning of the arc, where the arc coincides with the extruded circle (which selects the circle, instead of the arc) what in the world am I doing wrong? When I hover over the arc, it stays blue instead of turning orange.
