Indesign 'Align to selection' not working help

And in the meantime, you could copy the position value for an anchor point in the Transform panel, and paste it. (Or just use ruler guides.)

Definitely an Illustrator feature. Consider voting for this feature to be added to InDesign:

Select several, but not all, anchor points with the direct selection tool. It will align to the most extreme anchor. 

Hi @Dave_D26 ,

the feature you are looking for is not part of InDesign. I think, that Adobe Illustrator is able to do this.

In your specific case you can use a different feature of InDesign: just convert the polygon object to a rectangle.

Object > Convert Shape > Rectangle

From my German InDesign 2022:

I have never heard of this feature in InDesign, and I have been using InDesign since 2002. You can align objects, which will move some or all selected objects but will do nothing to change their shapes. In Illustrator you can average selected points horizontally or vertically, which effectively aligns them.

One thing you can do, and this works best with corner points, is select all the points you want to align with the Direct Select tool (white arrow) and scale the selection horizontally or vertically to 0%, effectively flatting the part of the path you have selected.

I'm not sure if it ever worked that way at all.

You can turn on smart guides and it should snap. But I don't remember ever being able to select and align nodes, maybe in Illustrator.

Maybe I'm not remembering correctly, I'm not on my computer to test.
