I am trying to place the corner rectangular box (see file) at a specific point in my assembly (the point in the corner where my two construction lines meet). How can I do this please?
Haven't opened up the files but can't you simple mate the points with rectangular box?
I opened your files and took a quick look. I don't have time to dig into it in depth right now, but it looks like a problem using the sketch to mate the first part inserted because the sketch is a child of the first linear pattern. I'd suggest suppressing all components, then create the sketch referencing only the assembly's origin and primary planes. Then you should be able to mate the component to the sketch entities.
And by the way, next time please Pack and Go your assembly to a zip file to post here. See Forum Posting .
