Improving 3D PDF quality
The scale of the imported geometry may affect 3D PDF quality. The minimum distance between vertices in the mesh of the polygonal model is 0.001 m (1 mm), for additional requirements please also refer to "RapidAuthor_Hardware_Software_Requirements.pdf" (located In Cortona3D Documentation for RapidAuthor).
To improve the quality of 3D PDF publications, select the Millimeters multiplier as shown below in the RapidConfiguration tool (Measurement units item) and click the Calculate multiplier button below.
