Re:Old Timer Question re Planking Thickness

[MICHAEL KERR]

If the hull was say steel or alum you would use the outside surface as the inside surface, blanking might no be uniform over the entire hull, eg under the waterline plannking might be thicker above a different thickness, if its even all over yuu could try SCALING but its hard to calculate, forming the interior surface is usually done in the Construction Module as of yet Delft doesn’t have one maybe Marven has got a method he could share with us.
