Trimming surfaces makes history crazy

[eobet]

The history feature in Rhino seems to be as old and unloved as the blocks.

I’ve only been using Rhino for a year, and already encountered numerous bugs it:

MatchSrf with History unstable

Ok, so almost a year later and I managed to create an even simpler example: [GIF 19.06.2020 09-54-48] This is really, really poor. I mean, this is really, really poor. unstablehistory.3dm (62.1 KB)

Blend surface doesn't blend the entire surface with history update

[GIF] I understand that the rebuild (with increased complexity of the surface) is expected behavior (any way to retain the original complexity, btw?*) but I don’t understand why it no longer blends the entire surface edge. That last part though, I really hope is a bug. Is it? And even if it’s not considered a bug during the implicit history update, even doing an explicit “blend edit” doesn’t reset the blend surface back to cover the entire edge, and I saw no option for it either, which I real…

Wish: rebuild and trim history enabled

I’m bumping my own thread here, but to… Trim a surface Inspect the design Adjust the construction surfaces Untrim Re-trim Inspect the design …is such a tedious procedure in Rhino. I’m going to do one of my terribly unfair comparisons that I’ve been trying to stay away from, but Rhino was much faster to rough out surfaces with up until this point. Now, I’m beginning to think I’m hitting the limits with Rhino and am beginning to wonder if, after all, and overall, Alias isn’t faster still? (Th…

MatchSrf history

In last night’s WIP, there is the start of history support for MatchSrf. So far, it doesn’t work with Average matches. I’m not sure yet when or if that will be supported. I noticed this morning that its a little shaky on getting multiple matches right. I’ll work on that. It should work on single matches to single or chained edges or to curve on surface matches. Let me know what you find.

Loft with history jumps to wrong edge glitch

Left is as the loft with history was created, right is after I extended the top surface to the left a little bit: [image] lofthistory.3dm (71.6 KB)

ExtendSrf messes up blend curves and an edge surface

Hopefully self explanatory GIF: [extendsrf] The middle surface that gets left hanging in the air is an edge surface built with the help of the two blend curves, all with history enabled. Seems Rhino’s history is really quite poor, unfortunately. This slows down the otherwise excellent surface sketch capabilities of Rhino. extendsrf.3dm (79.0 KB)

I only ever use history for maximum one or two steps (if it doesn’t glitch out) and then I kill it.

If you want stable history, use Autodesk Alias.
