    Congratulations for your videos. I also encountered several problems with this command from a polysurface without any errors after careful analysis tests, then after using _offsetsrf (20 errors that were not there and the surfaces sectioned), direction 0.20 as tolerance between male and female, _RebuildEdges didn't improve things either.
    Is there another method to give a tolerance of a few 0.10 mm for example? Ciao Thanks

      Applying offset to Polysurfaces usually cause problems, because upon creation Rhino used the file's tolerance to join the individual surfaces into a single polysurface. Depending on the offset distance and direction, this may lead to bad objects, because the joined edges are scaled into another size, hence the distance between them changes accordingly. The risk of potential error increases in areas where two surfaces are not perfectly tangent. Imagine that the file tolerance is 0,1 mm and, there is 1 degree deviation of the tangency between two flat surface (meaning there is a very difficult to notice 1 degree crease), and the offset distance is 100 mm. If those were separate surfaces, there would be a gap of approximately 1,7453071 millimeters between their adjacent edges. However, if the input surfaces are joined together, the resulting offset polysurface will have to rebuild each surface internally, in order to fill the aforementioned gap. while this is easy with flat surfaces, the rebuilding gets more complicated on curved surfaces joined together. This is the biggest reason for producing bad objects and open seams after using the "OffsetSrf" command.
