Unable to render

Hi, I have imported a revit model by converting it into dwg format into Velux Visualizer 2.

But the problem comes as soon as I start rendering, as there’s no preview to be generated in the rendering window. It can be seen in the image below that it’s blank.

Does anyone here as an idea, if I’m doing any mistake.

Hi @kartik.kaushal, you should post this question to Velux forum not here. This forum is for Ladybug Tools related questions. Thanks.
