Bug report: ArcBlend is not able to create lines

Hi,

Here is an exemple file :

With this inside :

If you use ArcBlend to link the segments A, it works.
If you use it to link the segments B, it doesn’t work, because the result would be a line.

I know the function is called “arc blend” but there is no “line blend” and frankly it would be tedious to switch between ArcBlend and this hypothetical function, I think ArcBlend should just handle this use case and produce a line.

Hi Felix - what is missing from the Line command for this?

-Pascal

@pascal Line works, what I’m proposing is an ergonomy and accessiblity improvement. It’s common to repeat the same function a few times when working on real life models (in my case I was closing a polycurve from which parts were previously trimmed out). Currently it works this way :

ArcBlend, right-click ArcBlend, right-click ArcBlend, oops it doesn’t work, why ? Let me see… Ah maybe because it’s a line ? Line, ArcBlend, right-click ArcBlend…

Yeah… I am not super keen to make a thing that is not an arc blend in the ArcBlend command. I’d prefer the command to report the input is colinear and not show the preview, would that help?

It would definitely help users understand what is happening yes.

RH-75337 is fixed in the latest WIP
