How to center construction points on rectangles

[fsonnichsen]

I think this was asked a long time ago and not necessarily the same thing I am looking for.

I simply want to joint-assemble two rectangles at their center. I choose the cumbersome construction line method shown in the attachment--8 clicks.  When I do this with circles it takes 2 clicks-simply select each circle. Strange it cannot be done with any symmetric object. I think we would use it a lot.

  I am guessing this has never been solved since at least 2016--but I thought I would ask-

Thanks

Not sure exactly what you want, just a joint? Joint will snap to the centre of a rectangular surface. This seems a bit too obvious so don't think this is what you want.

hi @fsonnichsen ,

I didn't understand very well what´s the problem, I had no problems to joint the two components.

You can find the file attached.

Kind regards.

Hi,

It would be helpful if you could say what you want to connect with what and how.
Unfortunately, it is not clear from your question whether you are talking about sketches, bodies or components.
A screenshot supplemented with markings could already help here.

I am trying to Joint assemble 2 rectangles at their centers as shown in the diagram.

The problem was that I did not see, in "Construct",  any method for placing a point at the center of a rectangle. I did see one for "Construct: Point at Center of Circle" which sort of threw me off. So my question was --is there a simple way of doing this.

  As Mark pointed out it is "obvious"--you basically don't need to do anything. I don't believe this is documented. I guess my original problem was that when I rolled over the "bottom" face it was not "lighting up" with a center point. I tried again a few times and it worked.  Maybe my recent flu shot has something to do with it. NAH!

  So my problem is solved. Of course it leaves the open question--why do they have an explicit means to do this for a circle?  I tried it Mark's way on cylinders and it worked without selecting the Construct command either.

Thanks All

Hi,

I add to my above contribution once again.
You are talking about rectangles and points, but do not point which rectangle and which point are meant.
In future, please support your contributions with explanatory screenshots or pictures of hand sketches

@fsonnichsen If you want a easy method to make points for locate joint positions you can use the “joint origin” command inside Assemble tab.

You can use work points, sketch points and the already existing origin joints to make new ones at your desired location.

Kind regards.

  are you able to see the f3d  that I included  on my post (test-center v8.f3d)?  You can see the two rectangular faces and the points defined by the Construction lines. 

  That side I tried clicking on the f3d nothing comes up--so I am guessing nobody is able to see it. Not sure what happened as I have done this many times before

Hi,

When describing a situation, what is so difficult about using the names in the file, e.g. component 1 / sketch 2?

representing "they" here...  You are correct that in the Construction Point commands do not offer a "point on center of planar rectangular face", while there is "point at center of circle/sphere/torus".  And yes, there might be cases where such a construction point could be useful.  But, in 7 years or so of Fusion, to my knowledge, you're the first to ask for it.  Not downplaying your request, just pointing out my own experiences.  And there are ways to find that point - you've found one.  There are others that require less sketch geometry (one diagonal should be sufficient).  The most common place where that center point is useful - in Joints or Joint Origins, you can snap to that point pretty easily, as @HughesTooling shows in his video.

Thanks Jeff-now that I see that points can appear without necessarily creating them via the Construct command I can use that--I just have to look more carefully when the cursor "lights one" up. I all makes sense now-
