Draft_tutorial: cannot mid snap on wire and circle

Postby francoislark » Thu Jun 02, 2016 5:51 pm

I successfully began with the Draft_tutorial, but couldn't add the dimensions on wire and circle. The mid-snap tool was working for the side of the polygon, but selected a 9 hour point on the circle instead of the 12 hour point as shown in the tutorial. The mid-snap didn't select any point of the wire.
I guess the circle has a starting point that is also its ending point, hence the mid point should be diametrically opposed to the starting/ending point.
But I have no idea how the mid-snap tool is supposed to determine a mid-point of a wire.
Am I missing a step in the tutorial ?

Hello Francois.

Welcome to FreeCAD and the forum.

Sometimes the different Snaps "fight" against each other.
Best to have only one or two active at a time.

Also i think the tutorial incomplete/incorrect.
For snapping to the 12 o'clock-point of the circle i would recommend the angle-snap.
For snapping to the center of the circle i would recommend the center snap.

Thank you for your help !

It worked with center and angle snap activated for the circle.
It worked with center and mid snap activated for the wire, but not on the original figure of the grid, only on the 2 duplicates...
