Is it possible to use a demolished line type with crosses? --X----X----X--

[Anonymous]

In AutoCAD there is a standard demolished line that complies with German building permit plan guidelines (I'm in Berlin), but this line does not exist in Revit. I searched the forums and the problem seems to be known to German Revit users since the dawn of Revit that there is no solution.

I know I can create a new family, but drawing over all the demolished elements is not BIM.

I tried importing a DWG with the appropriate AutoCAD line, but Revit imports the --X----X----X-- line without the Xs, like this: ---- --  ----  --. The Revit line creation tool is no help either, since you cannot use Xs for your line there.

Is there a way to get the standard yellow crossed demolished line in Revit (--X----X----X--) or is there a good workaround? Any help would be most appreciated.

I would recommend creating a line based detail item with nested annotation.

-Consider piping.

-Or curtain wall method

No.

As you know, this is a known limitation of Revit. Anything you do to accomplish this would be manual drafting and not be "BIM", as you say.

This is what I am most likely going to do since I only need the lines in the building permit plans, but this basically means I am reduced to tracing lines in Revit. I noticed that complex lines in DWGs aren't displayed properly either. So there really is no native support for more complex line creation in Revit like in ArchiCAD or AutoCAD?

It seems to be a well known problem, do you know if this is something Autodesk is thinking of implementing in Revit?

In every country other than the US, you may find some standards that are not supported by Revit. I say if we all adapt to BIM, we might as well change our presentation standards (its just presentation anyway...). If you create a legend where you explain some Revit linetype that is used for the demolished elements, I don't think that anyone would mind. As long as everyone understands your drawing, it should be fine. But, I don't know if you re obligated to use only --X----X----X-- line in Germany. If you can't use any other line, I suggest you create a voting group and post an idea for future Revit release. I really doubt that you cannot change your traditional presentation standard, because if that was true, --X----X----X-- would probably be implemented by now.... There's a lot of people in Germany who use Revit, right? 🙂

Yeah, after digging around this is the conclusion I'm coming to. It's a shame that line patterns in Revit can only be made up of lines and spaces (I just read that a point is actually a very short line). I'd be very happy if there were some more possibilities offered there, but maybe that's just a fundamental thing Revit cannot do.

Anyhow, thanks for the answer. I appreciate it.

I think it depends on whoever sees the plans. In accordance to the BauVerfV in Berlin, the demolished line should look like this. Perhaps they'll be fine with a slight deviation if it's well-labeled, but there are a lot of sticklers here.

I'd be very happy if the law was changed to just being a yellow line (but I suspect the Xs are there in case the plans get copied in black and white). It's probably not such a big issue in countries where you work less intensively with existing structures, but for now Berlin is Berlin.

Thanks for your reply.

I have created a detail item according to your line pattern which will show "--X----X----X----X--". All you have to do the change the spacing according to the scale.

What are the "Xs" in the ACAD Line Type?  SHX, TTF or just Lines?
