Weird Create Hole Behavior ...

[agordon]

Created a simple extruded plate with lots of holes.  Tried to change the existing extruded holes (created from a sketch), and the Create Holes (from the MODEL > CREATE menu) is creating a hole at 90 deg to the axis of the existing hole (see image below).  Really strange ... If I use a "point" in the Sketch, the hole works file, it just doesn't work if I use a circle and extrude from it.  

Screencast and file attached.

I've attached a file here ...

Holes are created normal to the selected face, which means that behaviour is by design.

That still seems weird, or counter intuitive, given that the "Thread" CREATE function works perfectly.

When I first started writing code, I was always told "if it doesn't work as the customer thinks it should, then it is easier to change the code than change the customer".

If this "as designed" then the design isn't working ... imported STEP parts often come over with holes intact, but not threads, so adding threads via CREATE > THREADS works fine with existing holes, but the CREATE > HOLE function doesn't ..... looks like a bug or an object that needs to be tweaked.

 You select the wrong face and wonder why things going wrong! I sincerely hope that Autodesk will not adapt the behavior to your wishes.  In this case, it's better to change one customer than all the others.

The thread tool and hole tool work completely differently, the hole tool allows for holes in the sides of cylinders a thread will always be along the cylinder.

For what you where trying to do you should have selected the face first then drag the hole to its position\reference.

The first input that the Create>Hole command wants is for you to click on a FACE that the hole should be perpendicular to. You're clicking on the inside diameter of the existing hole.

Why are you trying to use the Create>Hole command where there is an existing hole anyway?

If you MUST do this for some reason, first click on the FACE and THEN click on the existing hole to set the position.

The file has a lot of holes from an early sketch.  The holes have be countersunk on the extrude face (not the sketch face) and threaded (so if I use the HOLES command on the sketch, the CSK is on the wrong side (yes, I could extrude in the other direction, but this part is already embedded in a complex assembly and it blows up if I try that!).  So I have a hole that needs to be CSK and threaded, for which the hole command would be great, if it would work with an existing hole .... 

The problem is easily solved by adding a MODIFY > CHAMFER  followed by CREATE > THREAD command: I was hoping for a simple fix that allowed the hole command to be used that saved me from Machinery's Handbook to find the depth of the CSK!

I have an request on the ideastation asking for an improvement to the hole tool so you can use a single sketch for holes on both sides of a body or even one sketch for multiple bodies at different offsets from the sketch.

Thanks Mark, your request makes a lot of sense and would enhance what is already a pretty useful tool greatly!

Just voted!
