I have been working in rhino6 for some time and found out something I considered pretty cool. When I would extrudesrf a polysurface, the software would automatically modify the polysurface. Similar to the push-pull command on sketchup. This was especially useful when having to modify the dimensions of elements rather than extruding then using boolean difference / split / trim to modify.
Nevertheless, I’ve recently started to use rhino6 in a new computer and this command is not working anymore i.e. it is working as it use in rhino5 - meaning that when I use extrudesrf I creates a new body.
Anyone knows how can this be changed?
