Why is the rendition of my document blank?

The Meridian Cloud platform currently generates renditions of the following file formats:

• AutoCAD (.dwg)
• MicroStation (.dgn)
• Office (.xls,.doc,.ppt,.xlsx,.docx,.pptx,.txt)
• Images (.bmp,.gif,.jpg,.jpeg,.png,.tif,.tiff,.wmf,.emf,.ico)

Additional formats might be supported in the future.
