How to construct a point between two points via CONSTRUCT

[componentscience]

How can a point be created between two existing construction points without creating a sketch? The two points shown below were created via the 'CONSTRUCT/Point at center of circle' dialogue. How do we construct another point exactly between these points without creating a sketch.

[davebYYPCU]

Without a sketch (or body) - No.

What would you do with it if you could?

[etfrench]

It is possible to create a point between two other points, all of which are created using the Construct menu.  As @davebYYPCU says: What can you do with it that is useful?  Perhaps a joint origin or use it to measure something.

[davebYYPCU]

But what if you hide the body and do it - not possible.

WorkPoint requires some other geometry.

[jeff_strater · Accepted solution]

you can do this (in this particular case, of starting with holes), but it takes several steps.  There are a couple of missing construction methods that would make this easier - if plane along path accepted an axis as a path - but this does the trick.  Reminds me of middle-school geometry problems using a compass and protractor...

But, I gotta ask: why?  It's so easy to do this with a sketch.  What is the objection to using a sketch?

[etfrench]

How can you actually use a Construct point?  The only thing I've found is as a Joint Origin, but that's already available at those points without create a Construct point.

Clients often send exported STEP files that are extracted from massive assemblies that do not align with Fusion's global plane. In the included example, it would've been possible to use the two holes to create a new alignment in the X axis. The center point between those holes would serve as the origin of a new plane, which could then be used for creating sketches or new geometries from that face.

[laughingcreek]

That doesn't answer the question of why you wouldn't want to use a sketch, which so far seems like an easier and more straight forward way of doing what you just described wanting to do.

@laughingcreek 

Sketches cannot be created on the face of a part that is floating in outer space somewhere - unless the alignment doesn't matter. In this case new sketches have to align to the two holes.

[componentscience]

The holes are not planar to the center point of the face.

[davebYYPCU]

Very sorry

your example block did not show the problem you actually have.

[componentscience]

The example block was only used to ask if this is possible. We are not at liberty to show the real part.

[davebYYPCU]

Don’t need the real part, just a real example,

Your flat block with 2 holes, was misleading, normal tools work in that case.

As @etfrench said, I don’t know what to use Work Points for, there are better tools available, than those (relics).

Want to start over?

[componentscience]

The question asks if it is possible to create a construction point in the center of the holes without a sketch. The example block is enough information to pose that question.

[davebYYPCU]

What part of Jeff’s movie did not answer your question?

[componentscience]

Understood every bit of his answer. He asked what the use case was for, hence the reply.

@jeff_strater   Why do the dialogs call axes lines?  Aren't they different😁

[laughingcreek]

so, getting back on track-

what you want is to be able to align a sketch in a particular way?  just the origin location, just the x-axis, or both?  are you able to do this with construction points?

[componentscience]

@laughingcreek 

Just created a new question titled: Aligning imported STEP files to Fusion 360's global XY plane.

[jeff_strater]

"Why do the dialogs call axes lines?  Aren't they different😁"

yes, but in the work geometry (construction geometry, but that term is confusing, iMO), commands that allow axis selection also allow linear edge or sketch line selection, so "line" was the most generic term we could come up with that covered them all.  Any linear entity.
