This is probably the message he’s seeing…hes already imported that texture one time before
Turbocad is capable of ACSIS solid, surface or smesh… SketchUp faces will import as surfaces…
Groups become groups of graphics
Components become block insertion.
Groups and blocks will contain the surfaces within…can edit within similar to SketchUp…
Groups n blocks can be exploded…explode too many times and becomes nothing more than lines and polylines…sort of nice if just wanting 2d grapics…
