Extrude a sketch pattern

kirk_2

Simple task using new circular sketch pattern - negative extrude of bolt circle holes.  I can't get it to work in this public doc:

Yup

 @Kirk looks like the circles you created are construction geometry. Onshape ignores construction geometry in features. I took the liberty of 'solidifying' them for you. Looks fine now.

When I open it I still see the same error.  Not sure what "construction geometry" means.

There wasn't a sketch selected for extrude 2. I added it and the cuts work. I then took two circles and made them construction so only 4 cuts are made. "Construction" is a style that means that the geometry is typically used to drive other geometry but shouldn't result in solid geometry when used, e.g. in an extrude. In the attached image I have depressed the button that is used to toggle it. You can see the two circles at the top are dashed, meaning they are for construction. The other's aren't. So when it is extruded there are four holes. Select one of the dashed circles and hit the construction button to toggle their state.

Perfect.  Didn't understand the construction toggle.  Similar to SW center line, but here it can also be used for the bolt circle without deleting the circle.

Yup
