Curves workbench

Perfect like this

Could someone give me a step by step on using snapping in create freehand bspline tool?

It is eluding me.

I'm attempting to snap the mid vertex of a new bspline on a profile (the profile happens to be in a sketch).

I get the bspline point moving at a distance to the cursor, and the report view keep repeating "snapping to none".



Edit: Got it! select the vertex of the spline, and ctrl-click the target vertex (or edge) and THEN hit s. Duh.

Sooo...when I open this file the following is displayed:

Code: Select all

Traceback (most recent call last):

And, before or after deleting the broken Gordon surface I can't select the line circles in red:

Did you update the workbench recently ? This should not appear with current version.

In the View Properties, "Selectable" is set to False for this curve.

Addon Mangler says it's up to date (Note: this on local built 0.20 master...if that makes a difference.)

Ok...but, I created this spline. I didn't set it that way.

Is it possible that it got toggled some how when I was attempting figure out how to use the 's' snap keyboard shortcut?

What does this mean? (Same file after some addition splines, but no change to the discretized lines.)

The Selectable property is toggled when entering / leaving edit mode.
So I suppose it may stay to False, if edit mode is not (or improperly) exited.

It definitely means that the workbench is not up-to-date.
Maybe you can uninstall / re-install ?

[drmacro]

Thanks!

Looks like uninstall/re-install fixed it.

[Petrikas]

Maybe with Surface.Filling ?

But I suppose you want to turn it into a solid with thickness ... that's where it fails unfortunately.

I am sorry for the slight off-topic. But I've spent a few hours, scratching my head how you got that smooth surface. If I delete your surface.filling and make my own, I can't get it to be continuos, even with the non-boundary edge added.

I noticed that the surfaces you made had different Boundary Faces and Boundary Order.

But I don't seem to be able to edit those (I get a hard crash)

Please help?

In the Surface.Filling UI, in the list of boundary edges, you can double-click an edge to choose its attached face and G1 continuity.
