What's the difference in the line types???

[Fatboy]

When picking line styles to use when making filled regions, for example, there are lines styles listed with and without arrows ( <xxx> ). What's the difference between the <Hidden> and Hidden lines??

Anyone have any insight for me??

Thanks,

Tony

The ones in <> are revit system linetypes and can't be deleted. All others are user created.

There are quite a few without the <> that are also system linestyles. If you look at a template default.rte, all of those are system linestyles. If you can't edit or delete one it is a system linestyle. Not sure why they don't all have the brackets around them, ought to if they aren't editable eh? :smile:

And on that topic, for the dear life of mine, I can't understand why so many absolutely useless linetypes were left in the default files by many different development people (judging by the different naming conventions used). I don't need any of them, whatever I need I create myself (and only very few of them too).

But regardless how many times I delete them from all the template files I can find, every time I open a new file they are there again. I hate them, they are messy, they are cluttering my linetype list and I don't want them!

Gee, I wish that people who created them cleaned their own mess before releasing the program out to the World... To me is just a basic house keeping - keep it absolutely minimal and only on the "need to have" basis.

Simple is beautiful!

Now that I had my daily whine it feels so much better...;)

All those linestyles are either used by system families or one or more of the stock component families. They are what Revit needs to function at a minimum regardless if you ever create one of your own.

I really wish you could rename them though. I don't use the Thin, Medium and Wide....those names are so subjective! We're using a naming convetion such as "Solid_1" etc. and we know what thickness that is (we have a little cheat-drafting view in the template that can be printed or displayed on screen to show what each one is). We also have other linestyles that we use for specific designations, such as sight lines. This way, we can then control their visibility in certain views with view templates.

All those linestyles are either used by system families or one or more of the stock component families. They are what Revit needs to function at a minimum regardless if you ever create one of your own.I actually tend to disagree with that.

I do NOT use ANY of the stock library families (obviously apart from the system families where I have no choice), I don't even install ANY library other than my own. And, on top of that, I never saw many of these line styles used or mentioned in any of the system families anyway. Yet, they are there if I like it or not...

And to say that the system needs them is peculiar too because the system is behaving absolutely correctly when I delete them. The problem is, that they (e.g. linetypes, materials, fill patterns, etc.) suddenly appear in only some family templates (even my own, which I cleaned earlier) and not the others (!!!). And almost always when you try to edit a family from within your project... even if that family was "clean" before and the project file is "clean" too! By "clean" I mean all that rubbish removed already. And when you load these to your project, they obviously bring with them all that mess too...

But the most important point I am trying to make here is that each and every family should have only these elements that it uses itself - NOT all the other too. In such a case, you would have in any project elements only relevant to really needed and used families, instead of the whole bunch of rubbish that you don't use anyway... (see pictures 1, 2, and 3 below).

I know that all my families carry with them only the elements (linetypes, line styles materials, fill patterns, etc.) they really need and use and none others! They are smaller in size, much easier manageable and create much less mess.

On your last two images - those are not "built-in and not used". Those are coming from AutoCAD imports and drawings. If you import a DWG into a family - it makes linestyles for layers. You need to delete them if you want to rid your family of them. Same for a project - you'll get linestyles for the AutoCAD imports which will hang around even after the import is deleted.

Actually, all three images show a ton of acad line types.

As Aaron suggested, those are all coming from acad drawings that have either been previously imported into families or your project template.

My version of Revit comes with 15 line styles that cannot be deleted. I could lose the Medium, Thin, Wide (we have our own set of eight line weights: Lineweight-1, Lineweight-2, etc.). But other than that, the remaining twelve look pretty important to normal Revit functionality. I mean, we could quibble over a couple others, but it just doesn't seem worth getting so upset about it.

It would be nice if there was an option to purge unused line types (and materials while we're at it) using the purge command, but there's not.

I do not import anything from ACAD (not at the stage when I am installing REVIT software anyway), so where they are coming from???????!!!!!! Because as soon as I install Revit (any new version) and open it for the first time, they are there already!!!

And I never used such named line styles in any ACAD drawing (or any other software for that matter). EVER! These are named so differently from my style of naming that I couldn't possibly be mistaken. Besides, I NEVER used anything imperial in my whole life, so how come some of them are imperial anyway?

These are shipped and installed on my computer in precisely that way, version after version from at least Revit 6.0 (I don't remember how it was in 5.0 and 5.1).

That's why I am so frustrated!!!

Hmm, it's obviously not that way with the US version.

Just to be absolutely clear, you're saying that you start a new project from the default Revit building template that comes with the brand new version of Revit, which you've never modified, and you go to line types, and all of those are listed?

Do you still have the old libraries installed on your computer? Are you sure you're getting the template from the library of the current version? For instance, if you've copied over your settings from previous versions, maybe you're loading a template from a long ago version that you did somehow modify?

There's got to be some kind of explanation!

That's why I am so frustrated!!!Have you ever downloaded someone elses family? They could come from there.
Have you been using the same template from release to relase? They could be there.
Those are not system linetypes.

Can you post your template?
