I just want to import an illustrator vector image as SVG and extrude and give a cool material to the shape.
Me too. The OLD Adobe Dimension was well integrated with Illustrator allowing the user to create a path and use Dimensions to convert it to 3D and even export to vector artwork. Dimension CC seems to have just stolen the name "Dimension" without providing similar capabilities.
The current version doesn't even allow me to edit the mesh. It's no replacement for the original "Adobe Dimension".
