parking space parameters issue

Hello, I would like to ask for advise, I am trying to retrieve parameter from parking space. 

I collect them like 

 

                ElementCategoryFilter filter = new ElementCategoryFilter(BuiltInCategory.OST_Parking);
                FilteredElementCollector collector = new FilteredElementCollector(this._uiDocument.Document);
                collector.WherePasses(filter);
                    foreach (var item in collector)
                    {
                        FamilyInstance parkingInstance = item as FamilyInstance;

                        if (parkingInstance != null)
                        {
                          //Get parameter
                        }
                     }

I can get, location, level, bounding box as usual. But my issue is when I want to get the width and the length. 

 

According to their rotation(as you can see in the pic) , width and length will vary in case of using bounding box.

if I get length and width using trigonometry I could fix the issue. 

If it would be impossible to get them. How could I delimit the parking space?

Re: How to place a Pipe flange using Revit API

so this is a problem that can be address in many ways, but first:
1)did your Pipe Accessory have the same parameter signed to connectors?
Revit will force you some times to keep same DN of Accessory as Pipe.

2)don't use none in Pipe Routing Preference, it not only look silly but can cause problems later

 

 

A) You can simply create instance and connect them with pies and fitting connector.

B) your way would work only if you would get the same effect as a user

 

there is no easy solution for this.

Get all geometry elements from a mass

June 11, 2019, 7:28 am

Hi,

 

I am using this method to translate Mass families inside of Revit into solid objects so that I can use this with the ExtrusionAnalyzer.Create() method. The method takes in 3 arguments: a solid, and plane, and an XYZ vector. I am able to successfully translate a Mass that contains 1 geometry element into a solid, but the problem arises when I am trying to convert a Mass with multiple geometry elements into a list of solids. When I do this, it seems that revit is having a problem with reading the geomery data and corrupts it when converting it into a solid. I am suspecting this because when I am doing this, I get an error thrown saying that the Extrusion Analyzer failed.

 

Here is my method for converting a Revit Mass into a Solid:

 

        public static List<Solid> GetSolids(Element element, Options geoOptions)
        {
            //    Create the solids list
            List<Solid> solids = new List<Solid>();
            //    Return if selection is not a mass element
            if (element.Category.Name != "Mass")
            {
                return solids;
            }


            // Get geometry element of the selected element
            GeometryElement geoEle = element.get_Geometry(geoOptions);

            // Get geometry object
            foreach (var subEle in geoEle)
            {
                Solid solid = subEle as Solid;
                if (solid != null)
                {
                    solids.Add(solid);
                }
            }
            return solids;
        }

It  was working fine when I add it to a list by doing listName.Add(GetSolids(massName, options).First(), but the problem arises when I do listName.AddRange(GetSolids(massName, options).

 

Any ideas as to how I would solve this issue? I am happy to provide more code should it be needed.

 

Thanks

Error: Internal setting is required by Revit and has been deleted

Hi all, 

 

I've had a search and I couldn't find any answers to this either here or using Google, but sorry if this topic is a repeat of another thread. 

 

I've written a script that uses Revit's PerformanceAdviser to purge a document, but it seems to also be attempting to delete Revit's internal settings. Has anyone come up against this before? 

 

Ideally I'd like to skip over deleting these, as it just causes Revit to crash. 

Any assistance would be appreciated, 
Thanks, 

 

Oliver

I seem to have fixed it by adding another check after casting the geometry object as a solid, so I am checking in the if statement if the solid is not null and if solid.Faces.IsEmpty is false. More testing is needed to check for sure that this is accurate though.

Hi there!

I have the same problem and I'm still unable to solve it, although I tried all instructions ...

I installed Revit 2020 and Visual Studio 2019 and I follow the instructions here:

http://help.autodesk.com/view/RVT/2020/ENU/?guid=Revit_API_Revit_API_Developers_Guide_Introduction_Getting_Started_Walkthrough_Hello_World_html

the addins directory in my computer seems to be :

D:\Program Files\Autodesk\Revit 2020\AddIns

so, I put the manifest file there, but I can't see External Tools in add-in tab, 

I'm really frustrated:-( , Can anybody help ?

I think the ScheduleField is different than the SchedulableField, where ScheduleField includes the Calculated Values, correct me if I'm wrong.

 

I'm not interested in editing the value, but rather the formula. It seems like it's not possible, however, unless there's something else I'm missing.

 

Thanks for the reply, Jeremy.

Automatically Connect Load to Panel

June 11, 2019, 10:48 am

I have an electrical load with 9 connectors and would like to automatically connect each of them to a panel by having the user select the load and panel.  My current approach is to create an electrical system for each connector and set the panel.  I am able to create electrical systems, however when I use the SelectPanel method and pass in the panel, I am given the error "The panel and circuit do not match".

 

The panel and load are the same voltage and both have the same number of phases.  I am able to manually connect them (Select load, click Power, ect...) without any problems, so why am I getting an error here?  Here is the snippet of code in which I create the electrical system for one connector and attempt to select the panel (load and panel are both FamilyInstance types):

 

TransactionManager.Instance.EnsureInTransaction(doc)
newElectricalSystem = Autodesk.Revit.DB.Electrical.ElectricalSystem
loadConnectorIterator = load.MEPModel.ConnectorManager.UnusedConnectors.ForwardIterator()
loadConnectorIterator.MoveNext()
loadConnector = loadConnectorIterator.Current
circuit = newElectricalSystem.Create(loadConnector, ElectricalSystemType.PowerCircuit)
TransactionManager.Instance.TransactionTaskDone()
circuit.SelectPanel(panel)

 

I am using Revit 2019 and coding in Python using Dynamo

Transferring an old Revit File to a newer version

Hi, I have been working a Revit file at my school, which runs on an earlier version of Revit, and I am trying to download the file I have been working on to my home laptop. I emailed myself the document but when I try to open the file I receive an error message regarding the older file type,

"The file was saved in a later version of Revit and cannot be retrieved in this version"  

I'm not sure what version my school is running on, but I am using 2017 Student. 

Is it possible to upgrade the model somehow? I know normally when downloading different custom models sometimes you have to "upgrade the model" but this option has not been made available to me.

Dear Mohsen,

 

Thank you for your query and congratulations on moving one step further with it.

 

I implemented code a while back to collect all solids from certain family instances, unite them into one single solid, and process that with an extrusion analyser to obtain a projection of the 3D shape into a 2D boundary curve in the XY plane:

 

https://thebuildingcoder.typepad.com/blog/2013/04/extrusion-analyser-and-plan-view-boundaries.html

 

That sounds quite similar to what you are trying to do.

 

I hope this helps.

 

Best regards,

 

Jeremy

Re: Array of Boxes (FilledRegion)

Hi,

 

There are different approaches to achieve this, i believe.


For example, you can create some local variables to store the x- and y-coordinate for each filled region.


Then, with the increment operator you can create something similar as shown in your picture.

 

I hope this is useful for you.

 

   int counter = 0;                          
    int x = 0;
    int y = 0;
 
    foreach (FilledRegionType frt in fillRegionTypes)
    {                                    
        List<CurveLoop> profileloops = new List<CurveLoop>();
    
        XYZ[] points = new XYZ[5];
        points[0] = new XYZ(0.0, 0.0, 0.0);
        points[1] = new XYZ(10.0, 0.0, 0.0);
        points[2] = new XYZ(10.0, 10.0, 0.0);
        points[3] = new XYZ(0.0, 10.0, 0.0);
        points[4] = new XYZ( 0.0, 0.0, 0.0 );
        
        CurveLoop profileloop = new CurveLoop();
         
        x = counter% + 1;
        y = counter/ + 1;
        
        XYZ pos = new XYZ(2.0 * x * 10.0, -2.0 * y * 10.0, 0);

        pos += new XYZ(0, 0, 0);
        
        for (int i = 0; i < 4; i++)
        {
            Line line = Line.CreateBound(points[i].Add(pos), points[(i + 1)%4].Add(pos));
            profileloop.Append(line);
        }
                                
        profileloops.Add(profileloop);
        ElementId activeViewId = doc.ActiveView.Id;
        
        FilledRegion filledRegion = FilledRegion.Create(doc, frt.Id, activeViewId, profileloops);

        counter ++;
