How to Constrain the Center Point of a Rectangle Sketch to a Plane

[mpulliam6CT22]

Newbie here.  Someone please walk me through this...   How do I align the midpoint of a rectangle sketch on the midpoint of a face of an extruded rectangle?  

I can find the center of a rectangle by drawing two construction lines from opposing corners of the rectangle, is there an easier way?

I have tried unsuccessfully to use the move tool, the midpoint constraint, the project tool, the and the align tool.

I am trying to move the lower rectangle sketch to the center of the dark grey rectangle just above it.  It is the side of an extruded rectangle (a component)

Thank you,

yes, drawing construction lines is the best approach here.  Construction lines from the corners of the face, plus the rectangle you want to move is what I would do.  If you use a Center Point Rectangle to draw your rectangle, you get those construction lines made for you.

Ok, thanks. So how do I align the center of the sketch on the center of
the face?

I like to use horizontal and vertical constraints to do this. If you use two corner rectangles or center-point you get the same results...

Hi @mpulliam6CT22,

The short answer is:  You cannot, today, change the center of the sketch.  Can I ask why you want to do that?  In most cases, the sketch coordinate system should not really affect the sketch behavior at all.  I find it's easier to just dimension from other geometry on the component.

That's not to say this could never be done in Fusion, it's just that there is no command to do it today.

I'm not trying to change the center of a sketch, just trying to align the center of a sketch on the center of the face of another component.  Sorry if my language isn't clear.  

I didn't realize that I had to select the project tool and the face of the component BEFORE I drew the sketch, and I also didn't understand the vertical/horizontal restraint.

Thanks for the help!

I_Forge: I tried to follow your video but I can't choose the midpoints of the lines (of either rectangle). Was this feature removed?

@Anonymous It was modified, now you need to hold the shift key down to apply a midpoint constraint.

Sweet! Thank you

This tip is amazing. No more drawing lines to get midpoints.....

Tried, but with no success. It actually doesn't move the rectangle; it shows a triangle constraint, but nog combined with the horizontal constraint.

There is a bug at the moment. You need to pick the point first then hold shift down and pick the midpoint of the line second. If you pick the midpoint of the line first it will not work.

I'm not sure we talk about the same. The idea is to constrain two rectangle centerpoints. In the video, the command used is the horizontal/vertical constraint with SHIFT key. That centers first horizontals and second the verticals. Therefore you must constrain two lines, not a point and a line.

[HughesTooling]

Sorry, there is another version of this, constraining a rectangle to a point that's similar. Should have watched the screencast. Anyway it's the same bug, all you can do at the moment is use the Horizontal\Vertical and add the points you're seeing then select them a second time with the Hor\Virt constraint or add points first.

The fact that people are having to ask something like this shows the floors in the software!!

If you want people to adopt this software it needs to be more intuitive and usable.  looking something like this up is really not needed.

Hi @mpulliam6CT22 ,

Here is a link outlining how I would constrain this:

Hope this helped!
