VIM Revit Core C# Library

If you are familiar with C# Revit plugin development, you can use the VIM Revit Core C# Library to embed the VIM exporting process within your own plugin.

Language: C#
Revit Versions: 2017 to 2025

Requirements

Please contact us for the following:

The Vim.Revit.Core.zip package
A valid VIM license string

Setup

Download and extract Vim.Revit.Core.zip
In your C# Revit plugin project, add a reference to Vim.Revit.Core.dll and make sure to copy it and its dependencies to your build output directory.

Sample Code

To export a VIM file from your own plugin, you will need to call the static function Vim.Revit.Core.Exporter.Export, for example:

namespace MyPluginNamespace
{
    public static class MyPluginClass
    {
        /// <summary>
        /// Sample export function
        /// </summary>
        /// <param name="revitDocument">The Revit document to export from</param>
        /// <param name="view3dName">The name of the 3D view to export</param>
        /// <param name="vimFilePath">The name of the output VIM file path</param>
        /// <param name="myVimLicense">The VIM license string</param>
        public static void MyExportFunction(
            Autodesk.Revit.DB.Document revitDocument,
            string view3dName,
            string vimFilePath,
            string myVimLicense)
        {
            var options = new Vim.Revit.Core.ExportOptions
            {
                View = view3dName,
                VimLicenseString = myVimLicense,
                // ... enable other options ...
            };

            // Run the export process.
            Vim.Revit.Core.Exporter.Export(revitDocument, vimFilePath, options);
        }
    }
}

ExportOptions Class

The Vim.Revit.Core.ExportOptions class provides configuration options for exporting VIM files.

Parameter	Description
Log `string`	The path to which export logs will be written.
View `string`	The name of the 3D view to export.
FallbackToDefaultView `bool?`	(Default: `true`) Determines whether to export a default 3D view if the given view name is not found.
ForceDefaultView `bool?`	(Default: `false`) Forces the exporter to export a default 3D view; ignores any given View property.
ViewLevelOfDetail `int`	Determines the level of detail to apply to the view prior to exporting. -1: Use the view's current level of detail 0 to 15: For increasingly high tessellation 8: For normal tessellation
Render3dView `bool?`	(Default: `true`) Determines whether the 3D view will be rendered as an image and stored within the VIM file.
OptimizeMeshes `bool?`	(Default: `true`) Determines whether VIM's mesh optimization is applied. This typically improves the mesh quality of curved surfaces like pipes.
OptimizeInstances `bool?`	(Default: `true`) Determines whether VIM's instance optimizations are applied. This may save on export times.
StoreAllViewInfo `bool?`	(Default: `false`) Determines whether the information of all the existing views in the Revit document should be stored.
StoreAllGroupInfo `bool?`	(Default: `false`) Determines whether all the existing groups in the Revit document should be stored.
Export3d `bool?`	(Default: `true`) Determines whether the 3D export process should be executed.
ImageDpi `int`	(Default: `150`) Determines the image dpi (dots per inch) settings to apply when rendering a 2D view. Valid values are: 600
ImagePixelSize `int`	(Default: `4096`) Determines the size in pixels of the image major dimension when rendering a 2D view.
ImageFileTypePng `bool?`	(Default: `true`) Determines whether a PNG image is stored when rendering a 2D view.
ImageFileTypeTiff `bool?`	(Default: `false`) Determines whether a TIFF image is stored when rendering a 2D view.
ImageFitHorizontal `bool?`	(Default: `true`) Determines whether to fit the image horizontally when rendering a 2D view.
ImageFitToPage `bool?`	(Default: `false`) Determines whether to fit the image to the page when rendering a 2D view.
StopOnError `bool?`	(Default: `false`) Determines whether to halt the export process if any errors occur.
TempExportDir `string`	The temporary directory path used during the export process. If left unspecified, the following path will be used: `%USERPROFILE%\AppData\Local\Temp\VIM\Revit Exporter\`
CleanTemp `bool?`	(Default: `true`) Determines whether the temporary files will be deleted after the export process. Used for debugging purposes.
Trace `bool?`	(Default: `false`) Determines whether to emit a detailed trace file of the export process. This trace file appears alongside the exported .vim file.
StoreShapeOutlines `bool?`	(Default: `false`) Determines whether to store line shape outlines when rendering a 2D view.
StoreSystems `bool?`	(Default: `true`) Determines whether to store MEP system information.
StoreRoomGeometry `bool?`	(Default: `true`) Determines whether to store room geometry.
StoreMaterialUsage `bool?`	(Default: `true`) Determines whether to store material usage per element.
StoreParameters `bool?`	(Default: `true`) Determines whether to store element parameters.
IgnoreEmptyParameters `bool?`	(Default: `false`) Determines whether to ignore empty parameters. This may improve export times, but empty parameters cannot be audited.
ParameterNameAllowList `string`	The pipe-separated list of parameter names to process. If empty, all parameters are processed.
StoreAll3DCameras `bool?`	(Default: `false`) Determines whether the information of all the existing 3D views in the Revit document should be stored.
Schedules `string`	(Default: `""`) The pipe-separated schedule names to store.
ForceFaceTriangulation LevelOfDetail `bool?`	(Default: `false`) Determines whether the face triangulation level of detail is forced to a specific value.
FaceTriangulationLevelOfDetail `double`	(Default: `1.0`) Controls the face triangulation level of detail. This value should be between 0.0 and 1.0, where 1.0 is the highest level of detail. Only applies if ForceFaceTriangulationLevelOfDetail is true.
RfaMaxLevelOfDetailOverride `bool?`	(Default: `true`) When set to true, exporting a Revit family file (.rfa) will automatically apply the maximum level of detail to the geometry.
ViewSheetSets `string`	The pipe-separated view sheet set names to store.
HideLevelIndicators `bool?	(Default: `true`) When set to true, the circular level indicator geometry will be hidden.
LinkTitleAllowList `string`	The pipe-separated list of linked Revit document titles to process. If empty, all links are processed.
VimLicenseString `string`	The VIM license string. This must be assigned to a valid VIM license string to successfully export a VIM file.
