Also, the Improvement Request forum section is quite a friend of mine, but I have never seen this Extrude Offset request. Cannot find it right now also... Crazy amount of votes you say?
One thing I see on the change log that wasn't mentioned is updating drawings from the version dialog actually works again!
Tested it on a document that doesn't update usually, and it worked. Awesome! I missed not having that feature.

We pull from both public requests/votes in the Improvement Request forum as well as private requests tracked with the same mechanism as our support tickets. In the case of Extrude Offset, there was nothing in the Improvement Request forum that we were pulling from.

There's an improvement request:

It was marked as already offered - which kinda missed the point.
The big miss with how it worked up until this new update, was that extruding with draft (even with second direction) used the sketch plane as the draft hinge. To me this was always a huge disappointment. I was so used to doing injection molded parts (in Solidworks) with many sketches on the default planes, and extruding from/to with draft.
Great update, I'm new to the Onshape, but love to see that the developers are constantly improving the software while listening to community. Big thumbs up!
I was using surface modelling a lot (Alias, Rhinoceros) so seeing the option for Boundary Surface is a huge deal for me. I know it's currently in development, but I seem to miss an option here to control Degree and Span value. So adding such thing would be a huge bonus for all surface modelers out there, who want to control their surfaces while creating them.
Also I did a comparison for Boundary Surface with Loft and Fill (both Match Tangent or Curvature) for different type of Base surfaces. All the Base surfaces were connected with two Bridging curves with Match Curvature option to the edges of such Base surfaces.
There's intro how the surfaces are labeled/colour coded. Same for all pictures cases.
Case 1 - Bases as planar surfaces
Comparing the surfaces in Color Map Visualizations looks Boundary Surface and Fills the same. Lofts have some peak and bend in circled area.Comparing the Curvature Combs, there are additional combs in V direction (let's say blue = V) for Lofts. Other surfaces look the same.
Comparing the Control Points we can see why the curvature was terrible in Lofts - they create additional control points near Guides making it impossible for future surfaces to Align to those free edges.
Fills seem to be the best option here, because they don't create extra points in V direction as Boundary surface (even they are flat, they are there).
Case 2 - Bases = Warped surface in one direction (extruded curve)
Comparing surfaces in Color map seems to be the same, except the flipped direction of surface - only Fill continues the correct direction.There's a question - is there a way to flip the direction of surfaces (inside/outside)?
Curvature combs seem to be the same.
Looking at the Control points - Loft and Fill creates unwanted extra control points on free sides. Tangent versions have many spans. Boundary surface seem to be the best option but creates additional U control points - will create problems with Curvature matching on such short distance.
Case 3 - Bases = Warped surface in two direction (four 3D curves creating surface
Loft Curvature has different peak in the middle and Fill Curvature is completely different compared to other surfaces.Loft has crumbled (not smooth) combs in V direction. Fill curvature is completely different, bud the connection to the base surfaces bumps up.
Loft Curvature went nuts. The control points created almost a loop there. Boundary surface seem to be best option, but still creates additional U control points not needed for Align to the base surfaces.
Sorry for long post
Thanks for this investigation. I'm finding so far that what I appreciate most about this update (as far as surfacing goes) is the control grid display. It really helps to see what goofy things Parasolid is trying to do with the parameterization/degrees/spans. I would love to have direct control over this - at least at the level of telling Onshape/Parasolid to not rebuild the input curves if possible.
With Fill, I'm missing the option that Solidworks has called "optimize", which basically tries to line up the edges of the underlying fill surface with the inputs, if possible. Sometimes that produces better results than some weird random orientation of U and V with a bunch of trims.
One note on the Color Map Visualization: I think the reason you might be seeing the "flipped" colors is that if the surfaces are not merged (Boolean union), the color scales and perhaps the normals are independent.
Mean Curvature Without Boolean Union:
After Boolean Union:
Gaussian, Max and Min don't care if surfaces are merged. Their scales seem to be relative to the entire visible part studio.
For the most part Loft is still much more powerful than Boundary....for now. As I said in an earlier post, it seems obvious that it will eventually support curvature options and internal guides (and hopefully more goodies like controlling degrees/spans).
The one thing that I've noticed that Boundary can do that Loft can't: with Boundary, you can change the Magnitude of the tangent values, even if there are boundaries in U and V. Loft will only let you do this if there are no guides (AKA, you have U boundaries, but no V).
Here are three copies of the same simple revolved surface with a rectangular cutout in it. The first is "filled" with a Loft, set to tangent on all sides. If I try to change the magnitudes from 1.0 to anything else, it immediately fails. The second is using Boundary, with all sides set to tangent, and all 4 of the magnitudes set to 2.0. The last is Fill, which in this case does something I didn't know it would do - effectively deletes the hole in the surface.
Didn't the Fill switch do Add? As it basically does when you try to create a surface from edges of another. I've noticed that since the Feature turned red and first I had no idea why, because I added the correct value for each side. Then I saw it's Add not New.
