# Where exactly is the midpoint of an infinite line?

When one draws a line in solidworks and then one checks the checkbox to make the line infinite... where exactly in space is the midpoint of the infinite line?

I would doubt if you ever find that

BTW what is the need to get to the mid point of the infinite line

Solidworks modeling space has limits so if you put an "infinite line" in that limit space, it isn´t infinite within that space. The midpoint of the line (vector) must be in the middle of that space defined by "plane" the line is "on". Otherwise the midpoint must be in the distance ∞/2.

So a SW infinite line is like Cell carriers unlimited talk & text which do have limits that teenagers can actually hit, thus incuring overage charges....?

Finding that could unlock many of life's mysteries.  The insight may change our core way of thinking that would allow us to finally answer things such as; which came first the chicken or the egg?  If we didn't try to find answers for these hard questions we may still not know things like; how much wood a woodchuck could chuck if a woodchuck could wood?  But now thanks to those who dared to asked and not be swayed in their pursuit of knowledge we now know that; a woodchuck would chuck all the wood he could chuck if a wood chuck could wood.  God bless the curious minded.

brilliant!

One might assume it would be the point (0,Y) for horizontal lines or (X,0) for vertical lines.

The mathematical definition of a line is infinitely extending and no endpoints, meaning it does not have a midpoint. But the more practical and common definition (which is actually a line segment), which most of us think of when we hear "line".

Specifically speaking, SolidWorks follows mathematics.  That's why you can't add a midpoint relation to infinite length lines.  Only Line segments.
