MEP example needed ... create pipe segment

Anonymous — Wed, 15 Jun 2016 05:31:54 GMT

REVIT 2017, Windows 10, C#. Metric.

I downloaded the API samples; excellent for standard items like walls, wirnows etc. MEP is not included in the sample API items.

Need to create ppe segment using known coordinates positions of pipe ends; also known is the system name, pipe type nad diameter.

System: Domestic Cold Water

Pipe Type: PVC-DWV

Diameter: 65mm

Included:

using Autodesk.Revit.DB.Plumbing;

Found method to create pipe...

Autodesk.Revit.DB.Plumbing.Pipe.Create(doc,sys1,pipetype1,level1.Id,new XYZ(0,0,0), new XYZ(1250,1010,0));

for doc and level I can use...

Document doc = ActiveUIDocument.Document;
Level level1 = (Level)ElementFiltering.FindElement(doc, typeof(Level), "Level 1", null);

but I have no idea how to provide the system ID and pipe type ID ... please help ...

Thank You,

Kevin.

Please try the following code and tell me the results:

            FilteredElementCollector collector = new FilteredElementCollector(doc);
            collector.OfCategory(BuiltInCategory.OST_PipingSystem).Where(ps => ps.Name == "Domestic Cold Water");

            PipingSystem pipesystem = collector.Cast<PipingSystem>().FirstOrDefault();

            Autodesk.Revit.DB.Plumbing.Pipe.Create(doc, pipetype1.Id, pipesystem.Id, level1.Id, new XYZ(0, 0, 0), new XYZ(1250, 1010, 0));

If it satisfies your need please mark this reply as an answer.

By the way, a huge thanks to Mustafa for his more accurate answer and his innumerable other answers recently!

You are incredible, Mustafa!

Thank you!

Cheers,

Dear Jeremy

Thanks a lot, you are my God Father and I dream of meeting you someday.

Thank you, both of you.

I managed to get it working with the combined input provided by both of you.

It was really interesting to find that I needed to convert metric units to decimal feet in the XYZ positions.

Sorry I did not reply earlier, had a long weekend break directly after posting the question.

Thx for your patience.

Kevin.

I do not see you starting or committing any transaction.

You cannot modify the database without that.

If you are new to the Revit API, please start by working through the getting started material:

http://thebuildingcoder.typepad.com/blog/about-the-author.html#2

Then, read about transaction handling:

http://thebuildingcoder.typepad.com/blog/about-the-author.html#5.53

Once you have that under your belt, check out this series of posts on creating a rolling offset:

It demonstrates several ways of calculating, creating and connecting pipes and fittings:

Good luck and have fun exploring!

Cheers,

Jeremy

Hi Jeremy,

Is there a way to create pipe segments using mouse clicks rather than the hard coded XYZ values?

Thanks,

Re: MEP example needed ... create pipe segment

recepagah12 — Wed, 13 Mar 2019 19:03:10 GMT

You can prompt the user to select a point and use it as XYZ input.

XYZ point = uidoc.Selection.PickPoint("Pick a pipe segment location");

I hope this helps,

Recep.
