Re: Get Only Visible Elements in Linked Documents
Dear Nate,
Thank you for your challenging query.
It is an interesting question and not easy to solve, as you already mention.
Just as you say, the custom exporter is probably the easiest and most reliable way to go for 3D views.
Another easy and reliable piece of functionality that might help here is specifying the view in a filtered element collector.
Have you made use of that possibility? Can you make use of that?
Here are some discussions by The Building Coder on retrieving visible elements in various situations:
- Visible Elements -- http://thebuildingcoder.typepad.com/blog/2009/11/visible-elements.html
- Determining Absolutely All Visible and Hidden Elements http://thebuildingcoder.typepad.com/blog/2013/08/determining-absolutely-all-visible-elements.html
- Retrieving Elements Visible in View -- http://thebuildingcoder.typepad.com/blog/2017/05/retrieving-elements-visible-in-view.html
- Retrieve CAD Import Geometry on Visible Layer -- http://thebuildingcoder.typepad.com/blog/2018/05/retrieve-visible-dwg-geometry-and-foreground-image-import.html
A few more techniques are mentioned in the topic group on retrieving elements using the FilteredElementCollector:
https://thebuildingcoder.typepad.com/blog/about-the-author.html#5.9
Most interesting of all may be the methods implemented by Colin
- https://github.com/jeremytammik/the_building_coder_samples
- https://github.com/jeremytammik/the_building_coder_samples/blob/master/BuildingCoder/BuildingCoder/CmdViewsShowingElements.cs
It determines all views displaying a given set of elements.
He discusses them in more detail here:
- http://forums.autodesk.com/t5/Revit-API/Revision-help-which-views-show-this-object/m-p/5029772
- http://stackoverflow.com/questions/44012630/determine-is-a-familyinstance-is-visible-in-a-view
I hope this helps.
Please let us know how you get on with this, and especially what solution you end up implementing.
Thank you!
Happy New Year!

Re: 3D curve rebar
Hi Jeremy, thank you very much for your reply. What I want is a method to create a rebar with an arbitrary 3D shape, which is sometimes required in the longitudinal reinforcement of double-curved bridge. I created a HermiteSpline from a series of XYZ points and use the curve as the center line of rebar. The MultiplanarRebar may not be the solution. However, I found the free form rebar may be able to do that. I will try that.

Print to PDF
I hope someone can help as I have been working on this for days and the solution continues to evade me.
I am working in Revit 2018 on C# and to avoid complication I have striped my code back to the minimum to try to find the solution.
Ultimately, I am trying to print to PDF utilising PDFCreator whilst providing a series of options to the user through the UI. For the purposes of this however, I have hard code some of the options into my code. One of the options will be the selection of the Settings however for the purposes of this I am utilising “<InSession>”.
My issue is when I SubmitPrint(view) all the options I have pre-set within PrintManager and PrintParameters would appear to disregarded during the print process. For the purpose of my test there is only one view in the ViewSet.
A simple test has been to amend the PageOrientationType and paper sizes, but to no affect.
private void PrintWindowsTestPage() { GetSelectedViews(PDFTreeView.Nodes); ViewSet ViewSetName = selectViewsData.SelectedViews; foreach (Autodesk.Revit.DB.View view in ViewSetName) { PrintManager printManager = m_revitDoc.PrintManager; using (Transaction transaction = new Transaction(m_revitDoc, "Print to PDF")) { transaction.Start(); printManager.PrintSetup.CurrentPrintSetting = printManager.PrintSetup.InSession; printManager.PrintRange=Autodesk.Revit.DB.PrintRange.Select; m_existingExportSetup.PrinterName=PDFPrinterComboBox.SelectedItem as string;//Set to PDFCreator; ViewSheetSetting viewSheetSetting = printManager.ViewSheetSetting; viewSheetSetting.CurrentViewSheetSet.Views=ViewSetName; viewSheetSetting.SaveAs("MyViewSet"); printManager.CombinedFile = true; printManager.PrintToFile=true; PrintSetup pSetup =printManager.PrintSetup; PrintParameters pParam = pSetup.CurrentPrintSetting.PrintParameters; pParam.ZoomType=ZoomType.FitToPage; if (Width>Height) { pParam.PageOrientation=PageOrientationType.Landscape; } else { pParam.PageOrientation=PageOrientationType.Portrait; } pParam.PaperPlacement=PaperPlacementType.Center; foreach (Autodesk.Revit.DB.PaperSize pSize in printManager.PaperSizes) { if (pSize.Name.Equals("A1"))//Work required to get actual Sheet size) { pParam.PaperSize=pSize; break; } } printManager.Apply(); try { pSetup.SaveAs("Test"); } catch (Exception ex) { } printManager.SubmitPrint(view); transaction.RollBack(); } } }
Please can someone help as this is driving me crazy?
In anticipation of your assistance please accept my thanks.

Aligning Plans across sheets
Hi everyone,
I am trying to create a macro that aligns plans from sheet to sheet.
Now i managed to create a macro that aligns viewports from sheet to sheet, but sometimes annotations on plans will modify the outline of my viewports, making the alignment bogus ( the centers of my viewports align, but it's not what I'm really trying to achieve).
Is there a way, using Revit API, to get the location of the project base point (or other points like grid intersections for example) relative to the viewport outline, so that my plans are aligned from sheet to sheet?
Thanks!

Finding pipes with slope intersection error
Hi everyone,
I am trying to find intersection point between riser pipe (vertical) and horizontal pipe (with slope):
using the following code:
Selection selection = uIDocument.Selection;
Pipe firstPipe = document.GetElement(selection.PickObject(ObjectType.Element, "Select 1st Pipe")) as Pipe;
Pipe riserPipe = document.GetElement(selection.PickObject(ObjectType.Element, "Select riser Pipe")) as Pipe;
// Get firstPipe geometry and connectors
ConnectorManager connectorManager1 = firstPipe.ConnectorManager;
ConnectorSet pipe1connectorset = connectorManager1.Connectors;
List<Connector> list1 = new List<Connector>();
foreach (Connector c in pipe1connectorset)
{
list1.Add(c);
}
Connector firstpipeconnector1 = list1.First();
Connector firstpipeconnector2 = list1.Last();
Line firstpipeLine = Line.CreateBound(firstpipeconnector1.Origin, firstpipeconnector2.Origin);
firstpipeLine.MakeUnbound();
// Get riserpipe geometry and connectors
ConnectorManager connectorManager2 = riserPipe.ConnectorManager;
ConnectorSet pipe2connectorset = connectorManager2.Connectors;
List<Connector> list2 = new List<Connector>();
foreach (Connector c in pipe2connectorset)
{
list2.Add(c);
}
Connector riserpipeconnector1 = list1.First();
Connector riserpipeconnector2 = list1.Last();
Line riserpipeLine = Line.CreateBound(riserpipeconnector1.Origin, riserpipeconnector2.Origin);
riserpipeLine.MakeUnbound();
// Get intersection point of 2 pipes
IntersectionResultArray intersectionResultArray = new IntersectionResultArray();
SetComparisonResult setComparisonResult = firstpipeLine.Intersect(riserpipeLine, out intersectionResultArray);
try
{
XYZ interpoint = intersectionResultArray.get_Item(0).XYZPoint as XYZ;
TaskDialog.Show("Info", "The intersection point is " + interpoint.X.ToString());
}
catch (Exception)
{
TaskDialog.Show("Error", "Pipes are not intersected");
}But the result is :
Although these 2 pipe are actually intersected. So I guess my code have problem with slope pipe of something else.
If you have any experience with this, please help me.
Thank you so much :).

回复： Finding pipes with slope intersection error
Hi:
Break point at
SetComparisonResult setComparisonResult = firstpipeLine.Intersect(riserpipeLine, out intersectionResultArray);
Step over, and watch the 'setComparisonResult', what is its value? It should be 'Overlap' if two bound lines are truelly intersected. Don't forget to check intersectionResultArray.Size or IsEmpty property to check if two lines are TRUELLY intersected.
Break point at you 'catch' block, check the type and message of the Exception, and modify you catch block like this:
catch (Exception ex)
{
// Break point here
TaskDialog.Show("Error", "Pipes are not intersected");
}Show furhter infomation of this 'ex' variable. It helps you to diagnose your codes.
And, careful when you use "catch (Exception)", because it swallows any kind of exception.

回复： Finding pipes with slope intersection error
Hi:
I copied some materials from "Revit 2019 API.chm" help file.
This file is located in the Revit API installation directory, and it's quite useful.
Intersect Method (Curve, IntersectionResultArray)
Calculates the intersection of this curve with the specified curve and returns the intersection results.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 19.0.0.0 (19.0.0.0)
Syntax
| C# |
|---|
publicSetComparisonResultIntersect(Curvecurve,outIntersectionResultArrayresultArray ) |
Parameters
- curve
- Type: Autodesk.Revit.DB..::..Curve
The specified curve to intersect with this curve.
- resultArray
- Type: Autodesk.Revit.DB..::..IntersectionResultArray%
Provides more information about the intersection.
Return Value
- SetComparisonResult.Overlap - One or more intersections were encountered. The output argument has the details.
- SetComparisonResult.Subset - The inputs are parallel lines with only one common intersection point, or the curve used to invoke the intersection check is a line entirely within the unbound line passed as argument curve. If the former, the output argument has the details of the intersection point.
- SetComparisonResult.Superset - The input curve is entirely within the unbound line used to invoke the intersection check.
- SetComparisonResult.Disjoint - There is no intersection found between the two curves.
- SetComparisonResult.Equal - The two curves are identical.
Remarks
The array of the intersection results contains one entry for each point where curves intersect. The following is the meaning of IntersectionResult members:
- XYZPoint is the evaluated intersection point
- UVPoint.U is the unnormalized parameter on this curve (use ComputeNormalizedParameter to compute the normalized value).
- UVPoint.V is the unnormalized parameter on the specified curve (use ComputeNormalizedParameter to compute the normalized value).

回复： Finding pipes with slope intersection error
Hi:
Another suggestion,
You created a Line by obtaining 2 connectors and both end of a Pipe, I cannot tell that it was totally wrong.
But you need to notice that these 2 connectors you obtained from ConnectorManager are End connetors. (Connector.ConnectorType property). If there is a Tap fitting on this Pipe or Duct, there will be problem, because the ConnectorType of a tap connector is Curve. If there is 1 tap connection on a duct, this duct will have 3 connectors at all (2 End, 1 Curve), which means you will never be sure that :
Connector firstpipeconnector1 = list1.First();
Connector firstpipeconnector2 = list1.Last();returns the corrector End connetor that you want.
Let's talk about your purpose. You want to obtain the Line of a straight MEPCurve element (duct, pipe, cable tray, conduit), is it right?
Simply use the following codes:
(MEPCurve.Location as LocationCurve).Curve as Line
Here is a RevitLookup screenshot for you :)
