The unbearable lightness of construction objects

[Anonymous]

I want to drill a hole in a simple solid. My hole centre is already perfectly located to my satisfaction via existing construction objects. So why aren't construction objects powerful enough to be used to centre my centre-point circle in the sketch, from which I'd be drilling my hole? Why should I have to take the extra step of using dimensions/parameters to relocate the centre of my hole with sketch objects, when I already have it parametrically located with construction objects? (yes, I know the local coordsys for the sketch is different from the construction objects)  And then add insult to injury: I cant use construction objects to anchor sketch dimensions. Arrrrgh!

Why? oh why are construction objects invisible to so many operations, where the use of them is frustratingly impossible a good percentage of the time? Why can't they be snapped to so much of the time? I can't count the number of ways they have disappointed me by being invisible to the pointer when I want to locate something with them in fusion. 

Construction objects: get a life!

hi cloudbase9,

so you can do this, but the order of operation is maybe different than you are expecting.  try placing your hole on the face, place it away from the point you want, then release your mouse button, but stay in the command, now click that point and the hole will snap to it.

One drawback however is the hole will not make a parametric relationship with that point; Meaning if the point moves and you want to keep the hole snapped to it, you'll have to edit the hole and re-snap to this location.  In most cases I'd use a combination of projected/referenced geometry and sketch points to keep the relationship tied between the hole and the "point"

hope this helps.

Sketch->Project->Intersect gives you a point your hole center snaps to and will stay snapped to.
