We have a project that consists of 3 files making up the whole building, All files are linked into each other as are the consultants structural and services models.

The project started life in Revit 2015. The file has suffered from duplicate linstyles for 8 linestyles that seem to replicate a number of times every day. The linestyles all seem to be civils related, but we have no civils model on the project.

We have got the site designer addin installed and wondered if it was connected to that??? we haven't used the addin yet, and this file is the building envelope and cores and there is no site information in it. The site is in yet another file in addition to the 3 that make up the building and the 2 internal fit out files.

The 8 linestyles are:

• SW Curb
• SW Feature Line
• SW Parking Lot
• SW Point Wipeout
• SW Retaining Wall
• SW Sidewalk
• SW Soft Terrain
• SW Street

Even though it isn't possible to create duplicate linestyles with the same name through the UI, this seems to be possible by whatever is causing the problem. I have used a Revit Python Script to find and list all of these linstyles and they all have unique ElementID's and I can delete them using these ID's again using Python Script. The linestyles are not in use by anything in the model so deleting them causes no problem. I ran the script yesterday and today there are 12 of each linestyle in the model (96 in total) because from running it 6 days ago there were 66 versions of each of the 8 linestyles in the model (528 linestyles) when I first ran it, they had been accumulating it for some time and there were 463 of each linestyle (3704 in total) It looks like there are between 10 and 15 accumulating each day, We are putting something in place to log this at syncronization time to try and spot if it is connected to a partular user or activity, but wondered if anyone else out there was having this strange behaviour.

The other project files on the job have 1 version of each linestyle and seem to be stable it is this one file that seems to have this problem.

Any help or observations appreciated.

This really sounds like exploded CAD inserts burried in a family.

That is what I thought as well. But I was assured from the person who did it, did not even link any CAD in the file. Personally I don't believe him. But never the less I thought I would investigate to see if anyone else has had any issues like this.

Not linked in families.... exploded in families.   Then the linetype is defined in the family and is loaded into the project each time the family is loaded..... Even if the line actually still doesn't exist in the family.

Makes Sense.

I will definately take a look at that.

One thing:

I did check out the feature line tool for the Site Designer Add-In for Revit 2015 and the line types that are created are perfect matches to the ones that are in the site designer tool?

But if no one is even using the site designer tool I do not understand still how it gets imported into the Revit file.

If they match that tool then I would assume it is brought in automatically by the add in.  You could start a new job and see if those lines existing in a new job.

Yup definately tried that already. Nothing has been added on you projects. Just the projects that this guy has touched. Actually to be more precise just the project that he did the site plan. The method he mentioned to me that he did was used the model line tool to do some of the work in.

All the other projects do not have this problem.

It will not be exploded CAD in Families.   All linetypes created there will be in the family category and are not available in the model unless you are modeling in place in that same category.

What doesn't make sense is the multiple linetypes of the same name. 

Send this to Autodesk please.

Ok Sounds good.

I will post solution on here once they get it to me.

Thanks for all the help.

Hi

I think I found out the reason. Not from Autodesk.

So this is just a tip for people to not get 80 new linetypes that are duplicated.

So in Revit 2015 there is an add-in called site designer 

Once you touch any of the commands on there just once,  such as feature line, or sidewalk or curbs, etc... it creates those 8 linetypes. 

Once you sync and everytime you sync it creates at least 8 more duplicates, so imagine syncing 27 times you will have 27 of the same line type show up.

So my advice is not touch that site designer tool unless you actually have a landxml file and topo in your file.

That is what I found so far. I'll keep digging if anything else pops up.
