I use solidworks for few years now and I always had a little problem with "Hole Wizard Feature".
On a volume, I create a normal construction 2D sketch where I want to put the holes (you can see it on the animation below).
Then I clic on "Hole Wizard Feature" (on the animation, my solidworks is in French).
Then in "Positions" menu, I clic on "3D sketch" and I select the 4 points of my construction sketch but the feature don't want it...
You can see on the animation, when I don't select a point on my 2D sketch, the hole is created...
any idea ?
