Joining Open Polysurfaces

Rhino
1

Hey, I’m following this tutorial, and all was going well until around the 29-minute mark when I tried to do a BlendSrf as Jean does in his video

The problem I’m facing is his edges are joined and mine are not

Here are the edges that I want to blend together:
Untitled2

This is what it looks like in the video once the blend is applied:
Untitled3

The bit I have selected here is half of what I was expecting to have selected when I clicked:
Untitled1

And when I try to BlendSrf:
Untitled4

I feel like I’ve gone drastically wrong somewhere, but I’m not sure where

Any suggestions?

Cheers

Hi -
You can use the ChainEdges option on the command line to select both edges on the upper polysurface.

It seems, that you selected the ‘opposite end’ of the 2nd rail curve. It looks like a diagonal sweep.

Sorry, I’m struggling to figure out how to “ChainEdges”. I can’t find a direct command for it:
-> Unknown command: ChainEdges

So I tried it along with SelChain, but couldn’t figure that out either

Hi -

It’s not a separate command, it’s a command-line option for the BlendSrf command.
-wim

Absolutely perfect!

To be clear on what I did:

  • Called BlendSrf
  • Clicked my working edge
  • Clicked on 1 of the split edges
  • Clicked on “ChainEdges” in the command
  • Clicked on the 2nd of the split edges
  • Pressed enter

That has worked great, thank you!
