Try to export Lights Geometry without its light source geometry (bulb or cone)

pbobz — Sat, 28 Oct 2017 16:29:55 GMT

Hi Fellow Programmers of the Revit API,

Any one knows how to not export the "light source" geometry.

I read somewhere on the forum that you can skip geometry based on solids face matrerial if it's name is "Default Light Source". However, in my case Face.MaterialID is always -1.

And don't see any way to export the light geometry without its light bulb/cone.

Any suggestion ? 🙂

Hi,

GraphicsStyle graphicsStyle = doc.GetElement(solid.GraphicsStyleId) as GraphicsStyle;

if (graphicsStyle != null)
{
   if (graphicsStyle.GraphicsStyleCategory.Id.IntegerValue == (int)(BuiltInCategory.OST_LightingFixtureSource))
   {
       // light sources geometry
   }
}

Thanks,

I tried something similar :

if (gStyle.GraphicsStyleCategory.Name == "Light Source")
continue;

but without any success.

Hope your BuiltInCategory way will work 🙂

Be right back to tell you,

Hi,

whenever possible, you should use the language independent approach.

Hi,

supposing you have a French Revit, the Category's name will be translated (by Revit) into its French equivalent (if it is a top level Category).

Thus, "Light Source" won't work, except you translate it into French...

Nop, same effect. I keep exporting light source geometries even when I skip those based on graphicstyle.

 foreach (GeometryObject obj in geoElement)
{
                GeometryInstance geoInstance = obj as GeometryInstance;
                GraphicsStyle gStyle = doc.GetElement(obj.GraphicsStyleId) as GraphicsStyle;
                if (gStyle != null)
                {
                    if (gStyle.GraphicsStyleCategory.Id.IntegerValue == (int)(BuiltInCategory.OST_LightingFixtureSource))
                        continue;
                }

                    ExtractSolid(doc, VRobj, solid, color);
}

Hi,

the GeometryInstance contains futher sets of geometry, it is a container.

Use the approach on Solid level, not on GeometryInstance level.

Excellent !

Thanks for pointing that to me.

It's working like a charm. Thanks for all the advices.
