I’m relatively new to Rhino so please bear with me, I don’t understand a lot of the Jargon!
I imported a timber mouldings pdf into a new rhino file. All of the closed curves extrudecrv/sweep1 and cap without any problems. Great.
However if I scale any object in the file, including object other than my mouldings, and continue working, Rhino decides that the exact same curves can no longer be extruded or capped properly. I am faced with the following messages:
‘Curves selected to extrude include self-intersecting curves. This may produce undesirable results. Do you want to extrude these curves?’ (Funny, they didn’t have self intersecting curves a moment ago before I scaled!)
Or if I can extrude the curve, when I attempt to cap it I get this message:
‘One attempted object is still open. The openings did not have closed, planar loops of edges.’
(Funny, it extruded and capped perfectly before I scaled!)
Please help, I’m going mad.
I have tried projecting the curves to C-plane before extruding to check if they are planar and they are. I have tried exploding and re-joining to see if there were any problems there. There are none. The curve is classed as ‘closed’ in object properties before extruding.
