Auto Circuiting Homerun Wires

Auto Circuiting Homerun Wires

After using Revit for nearly 10 years I'm surprised this hasn't been fixed or made into a MEP settings option.  I use the auto circuiting feature often as it saves a lot of time, but what doesnt save time is having to delete the homerun wire that stretches nearly to the panel and adding one in the is a more acceptable length.  It would be great if there was an option to either limit and standardize a desired typical length, of have the software default the wire to be a reasonable length, maybe 18" - 24" as opposed to the occasional wire length of 60'.

Amen! This is a great request.  It's something that should be simple to fix.

 

It's also a good example of how a problem in Revit Electrical can go unfixed for years and years.

I'd suggest editing the title to be a bit more readable so this can gain support.

Agreed.  I asked a few years ago while attending Gunslingers and I had hopes it would have happened back then, but hopefully it'll happen, even for a patch for 2017 and 2018.  That's the last missing piece for auto-wiring then it'll be slick.

That would be great.  I would also add the ability to turn off an individual arrow for a particular homerun compared to shutting the feature off for all homeruns.  Give us the ability to have this feature.

 Hi @wrtetro@glenbob305@dw_werner,

 

Thanks for the feedbacks, for "default the wire to be a reasonable length", usually, how would you determine the length of the home run? Will it quite consistent in the whole project? and how would you deal with the wire (home run) length in different view scales?

A home run should be about 1.5-3” and point generally in the direction of the panel (but not exactly). It’s just a symbol saying “this connects to that”.   I’m going to look for a few home run symbols and post them as examples. 

 

Revit draws a wire wire halfway across the sheet which is not usable to anyone. Many many folks don’t use wires at all except home runs on their electrical plans, relying on tagging instead since wires end up a spaghetti mess.

Thanks @glenbob305, examples for the home run symbols would be helpful! we would like to understand what would be the expected range for the homerun wire length and any difference in different view scales. Thanks again for the quick response!

As far as examples, I'd leave it up to the users to decide.  Revit has several leader options already that that would be acceptable to most others.  They should have an option to where you can change the homerun arrow type to a 20 degree filled, 20 degree open...whatever options they want.  There are times where we use a tilde or other symbols to denote that the circuiting continues to another level or discipline and we have to use a masking annotation over the arrowhead to work around this.  I would like to see the ability for the users to be able to change the look of the homerun arrow to whatever their company standards are, they should be able to create a family, load it into their template or project and change the type as required.  As far as the wire length shown on plan views, that's dependent on the scale.  at a 1:1 scale, I'd say it should extend out from the edge of the device 6" or about 36" on a 1/8 scale plan.  BHOMERUN_ARROW_EXAMPLE.JPGut it should not extend 3/4 of the way across the plan to the electrical room, this makes the feature useless.

First step would be to get rid of the really long home runs. They should look something like this:

Moving forward id really like to see Revit adopt a non-wire homerun that can move with fixtures and not change.  Maybe that’s a discussion for another time.

Thanks! This will make a lot of people happy. I'm part of the beta program and can't wait to test more new features.

There was an improvement made in Revit 2020.1 to address this... you should no longer see auto-generated homeruns that go beyond a reasonable length by default, regardless of view scale.
