Are there instructions on how to install this plugin and export models?

Jeremy,

Actually it's not an issue but a question. I'm working on a viewer with customized json format. However, I have some problem while tring to reuse geometry of family symbol with different transform.

As you mentioned in "the building coder", Revit API only provides a high level Transform class to expose matrix transformation relative information. But I need to assemble transformation MATRIX in a double array.

Here is my code to assemble transformation matrix:

Transform t = InstanceNode.GetTransform();
double[] matrix = new double[]
{
    t.BasisX.X * t.Scale, t.BasisX.Y,               t.BasisX.Z,               glOrigin.X, 
    t.BasisY.X,               t.BasisY.Y * t.Scale, t.BasisY.Z,               glOrigin.Y, 
    t.BasisZ.X,               t.BasisZ.Y,               t.BasisZ.Z * t.Scale, glOrigin.Z 
 };

And the frustrated render looks as screenshot rst_basic_sample_project (with transformation issue).

I checked the transform property of a couple of elements and found that:

1. elements with no rotation (3x3 identity, no matter what origin is) are rendered correctly.
2. elements with rotation are rendered incorrectly (direction is correct, but position is wrong)

The most possible reason is that I assemle transformation matrix in a wrong way. Could you please help take a look and give me some tips? Thanks a lot!

Hi Jeremy,

I play for a few weeks with the exporter and I would Add an new function : Possibility to export rooms (volumes).
I think this could be a nice feature !
I started by creating data to "_objects" (userData...) but I have problems for adding geometry ( in "_geometries") !

I don't know how I can implement correctly this geometry function (actually, I don't have created 3D rooms in the 3D view) ?

Thank you for your help.

Cheers
Thomas

I downloaded latest release 2017.0.0.0 and built in VS 2017 using DLLs from Dynamo 1.3 and Revit 2017 which were:
RevitNodes.resources.dll; DynamoCore.dll; RevitRaaS.dll; DynamoServices.dll; DSCoreNodes.dll; DynamoRevitDS.dll; DynamoCore.resources.dll; DynamoUtilities.dll; ProtoCore.dll; RevitServices.dll; RevitNodes.dll; DynamoRaaS.dll; DSRevitNodesUI.customization.dll; DSRevitNodesUI.dll; RevitAPIUI.dll; RevitAPI.dll

I generated the DLL into Autodesk/Revit 2017/AddIns/rvt/, and also copied NewtonSoft.json.dll and RvtVa3c.addin

The add in doesn't show in either the add in tab or as an export option when testing with a basic wall or with the sample projects.

Jeremy,

I use RvtVa3c to export a Revit file and encounter crash while doing CustomExporter.Export(). The reason there're some elements with null category property. I think it would be a common situation as I encounter elements with null categroy property in some other Revit files.

My approash is to add the following process in both OnElementBegin() and OnElementEnd(). I'm not sure if it's the right way, but at least it works for me.

        if (null == e.Category)
        {
            Debug.WriteLine("\r\n*** Non-category element!\r\n");
            return;
        }

Hey guys,

I followed the instructions on the front page.
I have been trying to add the add-in to Revit 2019 and while yesterday I manage to add it to Revit 2018 it is nog working now and Visual Studio gives me following errors:
I am not a programmer, so my knowlage to repair something is kind of limited.

Hope you can help me out.

Thank you kindly.

Hi Jeremy,

While reading the export logic in OnPolymesh(), I notice that you insert a 0 value index for every triangle.

int v1, v2, v3;
foreach (PolymeshFacet facet in polymesh.GetFacets())
{
//Debug.WriteLine( string.Format(" {0}: {1} {2} {3}", i++, facet.V1, facet.V2, facet.V3 ) );

v1 = CurrentVerticesPerMaterial.AddVertex(new PointInt(pts[facet.V1], _switch_coordinates));
v2 = CurrentVerticesPerMaterial.AddVertex(new PointInt(pts[facet.V2], _switch_coordinates));
v3 = CurrentVerticesPerMaterial.AddVertex(new PointInt(pts[facet.V3], _switch_coordinates));

**CurrentGeometryPerMaterial.data.faces.Add(0);**
CurrentGeometryPerMaterial.data.faces.Add(v1);
CurrentGeometryPerMaterial.data.faces.Add(v2);
CurrentGeometryPerMaterial.data.faces.Add(v3);

}

I'm quite confused by this line. IMHO, this 0 value index will make mesh messed up. However, va3c viewer renders model fine. Could you please give me a hint of it? Thanks a lot!

Cheers!

Can this get revit version by js quickly?

Hello, guys,

I am not able to build the solution using vs2015. I am not sure what DScore is. Is it possible that someone could release the built dll? Many thanks in advance.

when i build it, visual studio told me that err: “RvtVa3c.Va3cExportContext”did not
implete the member“Autodesk.Revit.DB.IExportContext.OnDaylightPortal(Autodesk.Revit.DB.DaylightPortalNode)”
i do not know what to do next.i use vs 2012 & revit 2015.

Hello,

Thank you for all the work on the Revit JSON exporter add-in.

For some reason the exporter fails when trying to filter the parameters of the objects to be exported. Please see below for a sequence of photos showing the general flow of the failure.

I am very inexperienced Visual Studio user. If more debugging information is required to show what's happening please make a specific request and I'll see if I can produce it.

Please note, this may be the same issue reported earlier for Revit 2019 as issue #17.

Best wishes,
Jake Staub

Hey guys, I am using 2018.0.0.0 to export vrt files, and I have correctly referenced RevitAPI.dll and RevitAPIUI.dll。
But I encountered an error when I exported the file。

Can you help me solve this problem?
Thank you！

hi, dev guys, when i try to export my test model using this tool in Revit 2020, some issues show up, the exception msg as following:

Anyone had the same problem, so what are your tricks to fix it? plz tell me, thx a lot!

Jeremy,

I exported a small MEP model and found that RvtVa3c skips element colors configured via filter. I tried to find related Revit API which could query element's filter color but there's no luck.

Could you please give me some clues about how to get an element's filter color? Thanks a lot!
