using construction lines as reference for holes

[1johnmurphy]

How can I use a construction line as a reference for positioning holes?  I would like to create a rectangle, change the lines of the rectangle to construction lines and then reference the position of the hole to the reference lines.  I'm using the rectangle to reference where a component on the object I'm creating is placed.  Is there a better way to do this?  Sorry, very new to this:)

The use of construction lines for placement of holes is unlimited.  Take a look at my Screencast for just a couple.  Remember, the hole command will be looking for points to snap to.  As you can see in my video, some are automatic but some you may need to place.  In the situation where I place a construction line at an angle and crossed the circle, I had to place a point at the intersection in the sketch.  If I had stopped at the circle, instead of crossing it, I could have skipped the point placement as there is one at the end of the line, oops!

I would like you to realize hole placement can be automatic such as placement in the center of a cylinder.  Simply select the end plane and then the edge of the cylinder to make the point jump to the center.  You can also dimension from edges during the hole placement command, both methods do not require construction lines.  It is all up to the designer.

That was very helpful.  I've noticed that you can attach holes to points on construction lines but if you want to use the line instead of a point then what i've resorted to is creating the rectangle (no construction lines)  attaching the holes and then converting the lines to construction lines after.  That seems to work as well - although I'm not sure that was intended lol. Thank again for your video.
