How to find X,Y intersection on an object with radius edges

When I want to move an object by selecting the back left corner of the object to 0,0,0 coordinate I just pick that corner on an object and use the move to 0,0,0

However when I have that same object that has radius edges on the corners I have to draw lines on the back and left edges on the object to find where they intersect ( See attached example )

Is there an easier way to find that point out in space on an object with radius edges?

Thank You!

Hi Kent -
You can use point filters to first set either x or y and then snap to the other.

You could use BoundingBox with output=curves maybe.
Or use Connect to find that intersection.

You could do this with BoxEdit with the “use bounding boxes” option as well.

Another approach might be to use the center snap on the corner arc and move it to radius, radius instead of 0,0.

Thank You everyone for your suggestions…

I tried the “use bounding box” option and that looks like that’s going to work.

However I can’t figure out how to turn the bounding box OFF afterwards?

I just figured out that the bounding box is an actual set of lines that can be deleted… ( verses turned off )

Thanks again everyone for your suggestions… ( I’m going to also try the other suggestions to see which one is the quickest to use on a regular basis )

Why not have yet another method - for a box, you can use the Along osnap (where I type ‘a’ in the clip) to place a point:

For less conveniently aligned edges the Line command, with Extension option will get you there:


Thank you very much Pascal… This will be a great option…

Dear @kentdesautel

In such a situation why not using the available underlying data ?

  • Click on the 2D entity to display the Cp’s
  • Snap on the desired CP
  • Move the object from that Location
