I am creating a 3D file with help of a Reference Autocad file, But after linking i can't select SPlines from the linked cad file. Whithout getting that SPline it will be difficult to create the curved sloped floor. I have created it in another way but the slope isn't correct. if i get the SPline i can eaisly create that sloped curved floor. Is there a solution for this?
I have already tried Flatten and PEdit method but i haven't got a continuous line for selecting.
