"Hi Ryan- you can, at least for top level blocks, but there is no way to highlight the edge you are duplicating until the command ends.  -Pascal pascal@mcneel.com"

"Ryan, It might be overkill for what you're doing, but the Orca3D plug-in computes the volume of surfaces, meshes, or solids at any arbitrary plane. You can set the volume units to just about anything (gallons, barrels, liters, cubic feet,…"

"Hi Ryan, You can always write a script to do the calculation. Here is an example: https://github.com/mcneel/rhinoscript/blob/master/MyVolume.rvb Multiple the number of cubic feet by 7.47 to calculate the total volume in gallons.  -- Dale"

"However, this does not appear to apply to release candidates, only official SR's...  ----H"

"It's here.  Accessible from the main download page, click on the change log link. ----H"

"Here's a Rhinoscript that will do this using two rail curves.  Drop it on an open instance of Rhino to test.  You can add it to a button or make an alias for it if it seems useful.  Not heavily tested.  Let me know if it…"

"sorry to be a pest but I find this to be a real annoyance. Looking for some acknowledgement that this is on an issue ticket somewhere or some instructions if I'm doing it wrong."

"I would use for this too but would be nice to be able to toggle it on a per-polysurface basis."

"Hear anything about this Pascal?"

"Yup that's what I was asking. Thanks Pascal."

"Hi Ryan - if you mean fillet a corner of just a curved surface that has no thickness, no there is no direct way to do that. One way out is to BlendCrv between the edge curves and use the resulting curve to trim the surface. Is that what you are…"
