Fastest way to place a line in the midpoint of two lines.

I've got a building with a bunch of unique room layouts. I have to draw a polyline to callout a keyed note. Simple stuff but time consuming since I can't copy between rooms. Is there a way to draw a line in-between those walls faster than grabbing the mid-point of a guideline or using the midpoint command (shift+right click).

Use Mid between 2 points?

@zbischof ,

Also, take a look at the YQARCH plugin.

If this is what you're talking about it is pretty fast. I was wondering if there was a one clicks solution like a offset command that adjust to hit the center or something like that.

Use object running snap?

Mid-of-2-points Object Snap doesn't make sense as a "running" mode, since it requires two picks to implement. Some other applicable mode would "kick in" on the first pick you make, so mid-of-2 wouldn't ever be applied. That's why it doesn't appear in the OSNAP command's dialog box for setting running modes, but only appears in the one-shot call-for-it list [Shift+right-click or Ctrl+right-click], at the top above the runnable-modes listing along with others that don't make sense as running modes [e.g. 'From'].

Using Mid Between 2 Points via Shift-Right Click requires quite a bit of keyboard (shift) and mouse click coordination. In addition, you often don't have two points that will yield the desired midpoint. It might be easier (and faster?) to create a construction line first and then snapping using the midpoint. For example, with osnap nearest, endpoint, and midpoint active create the red polyline for the walls as shown.

You can now use offset-through to create the green lines ny snapping to the midpoints of various red segments.

Chamfer is used to clean it up.

In most cases, an APParent-intersection call will get you the point(s) desired. But in the situation you illustrate, using temporary helper Lines, I would do it as in the left side here [the red ones use ordinary running ENDpoint or INTersection Osnap; the yellow ones all involved APP Osnap at one end]:

Then you just set MIDpoint Osnap as the lone running mode, and run around doing the green lines in the right half -- no Chamfer/Fillet/Trim/Extend operation(s) needed.

But that's only if you feel more comfortable having helper Lines of some kind [which you then need to delete]. It can all be done without them, using a combination of M2P [or MTP] and APParent-intersection calls.

@Kent1Cooper I didn't think of Apparent-intersection. It does reduce the need for offset and chamfer.

I created one continuous "helper" polyline, rather than a bunch of them, to simplify deletion after creating the midpoint line.

That makes sense, though it's counterbalanced by the need to Chamfer/Fillet/Extend/Trim the midway linework. Everything's a trade-off....

@zbischof CENTERLINE command https://www.youtube.com/watch?v=lw2AJbajUfU
EXPLODE afterwards then FILLET as needed (if they are created on a unique layer in the first place you can just LOCK all the other layers or FREEZE the the other layers to get them out of the way).

All of the above is even faster if you've developed LISP tools to lock-all and feeze-all layers more quickly.

OSnap Tracking

The Route Line add-in from UHP Process Piping, Inc.,with setting OSNAP to INT, and a toolbar of point filter macros simplifies the creation of an in-between polyline (exploded from a Route Line) to a selection of mouse clicks.

I ended up going with a mix of different methods mentioned here. Thanks for all the ideas!
