Drawing a curved insulation in 2d detail

[Anonymous]

Hello everyone, 

Could someone please explain to me how is it possible to draw a curved insulation in 2d detail with Autodesk Revit as shown in the picture below? 

Many thanks.

Draw it as short segments.  It will not be as clean as what you show but it should be adequate to delineate the intent of the detail.

Are you talking about Batt Insulation (Annotation Tab)?

I read that he wants to wrap the batt insulation around the turn as a continuous curve, not segments.  But you might be right that he actually just needs to know how to draw the batt insulation after all.

No, I'm the nincompoop. You're right, @ToanDN.

Hi @Anonymous

Welcome to the Autodesk community!

Please see a video on how to create a Detail View below:

See AKN articles:

1. Create a Detail View

2. Draw Detail Lines

so is there any update? I didnt really understand the answer if there was one. Is there a solution which would look presentable? If i draw it in short segments then the ends wont connect to each other, if I draw it with detail lines, it looks horrible.

The closest solution (which took 1 and half hours) was to use detail lines, choose the elliptic pen and then draw ellipses, cut the other half of the ellipse away, and then mirroring the remaining half to the other side and moving them a bit. It still doesnt look like anything i would show to anybody.

The batt insulation tool only does straight segments. it will not do an arc segment like shown in the original image. If that look is important to you, you will need to do manually or maybe make some families that have the standard radius you use for that detail and put it in that way.

As I see it, I would probably just do it in straight segments and be done with it. I can't imagine a situation ever where drawing it like that would ever confuse someone to the point that it would matter.

In my mind the difference between those 2 details is not worth 90 minutes of billable time.

I know the posts old but it is still hard to believe Autodesk has not found a remedy to this curved batting issue. We have situations where it would be so much better (and quicker) if you could insert a batting to suit any line - straight or curved.

I created a Dynamo graph for this.

See the link below.

That really isn’t how it would be constructed, therefore I wouldn’t draw it like that.

AutoCAD AEC in the UK had a command for drawing that back in the 80s - could even be tapered 😀

It's always fascinating to see Autodesk employees reply in support threads, completely misunderstand the problem and offer an unsatisfying solution, and add "please select the Accept as Solution" when no solution has been offered. The answer in this case is of course (like many times before) that Revit can't do this.

[per.hultcrantzYAHE4]

Of course, these answers are common as well – "just do the opposite of what you want and be done with it".

Has anyone used @dingohot 's solution for creating curved insulation? I'd like to know if anyone else has attempted to use that dynamo workflow to accomplish this task, before I do it myself.

Hey!

I don't know if you found an answer, but I was looking to do the same and came across this blog:

http://plevit1.blogspot.com/2013/10/curved-insulation.html

They show a very "revity workarownd" that seems to work. As most of this workarounds, the path to the solution is far from simple, but also as most of revit, when you invested the time in setting up the family, it works from then on and ends up saving time in the long run.

The math is a bit complicated for me to try out for now, but I find it very cool! It is for you to decide if the effort is worth it in your case!

Good luck!

Thanks! I found this plug-in, which worked really well: https://github.com/mikaeldeity/CurvedInsulation

It's a very old post of mine.

Here is a recent one using dynamo.

Thank you @per.hultcrantzYAHE4 and thank you @dingohot ! Pretty cool! I'm glad we keep finding new ways to do stuff! 

The internet works in strange ways, when I was searching, all the posts I kept finding were from 2013-2014 xD

Insulation can bend...so what are you talking about
