Re: Creating a hole on a curved surface

11-20-2012 10:13 AM in reply to: leweaver

Here's another example to go with JD's.  It's all constrained and easily and predictably editable.  Your original hub has four countersunk holes that are a mystery since they are threaded, and they're too close to the hub.  A #5 flat-head screw would run into the hub in that position.  Pull the EOP up to the top and go through it feature by feature; ask if anything doesn't make sense to you.

Thanks Sam! The first solution worked perfectly. And no, I have not been trained in this or any Autodesk product. When I learned CAD, we used SolidEdge but I have been trying to self-teach some of the Autodesk products for a project that I am working on. Trying to get it done the quick and dirty way, I often forget to constrain my sketches... Thanks again.

If you do it right - you don't have to constrain your sketches - Inventor does this for you.
That is why you should worry about it now, once you learn how Inventor will do the work for you it all gets must faster.

In my experience the "quick and dirty way" always ends up being the slow and dirty way.  No winning solution in that.

Re: Creating a hole on a curved surface

11-18-2013 01:29 PM in reply to: leweaver

I am trying to create a hole on a surface that is not flat. I am unable to create a sketch or a work plane due to the curved surface. I need to place a hole on the side of the open end 1.125" up from bottom. Any help would be appreciated. I am workinng with Inventor 2013

 

  Thanks, BB

I noticed that several of you sketches are not fully defined?

see attached for one method.  (I didn't take the time to try to get hole in precise position as I don't know relative to what?

Sorry about that, I need the hole perpendicular to the surface you have it on, Ive relocated the hole into proper location, just not clear how you were able to create the work plane. Did you create WP 5 and 6 to get the axis?

 Thanks

I will come back tomorrow with instructions on more precise way of placing the hole.

The key is to get the perpendicular pierce point where the axis of the hole passes through the curved surface.
