Pickable control polygon

(Mikko Oksanen) #1

In the latest WIP it’s possible to enable selecting control points by clicking the control polygon. The setting is at Tools->Options->Mouse->Make control polygon pickable.
When enabled, single clicking a curve or surface control polygon chord selects the two control points at the ends of the chord. Double click selects the whole row of points.
Please give it a try and let us know what you think.

This great…

How does the double click work? Do I need to click once first?

(Pascal Golay) #3

Hi Bob - Double-click should work directly. Click-click on the control polygon segment.

I like this a lot. Thank you Mikko.

I wonder if further functionality could be added by pressing the up/down arrows to progress/regress the selection down the control polygon? That would be the icing on the cake!




It’s technically not a double click. It’s two consecutive clicks or somewhat slow double click. I find it very useful as we work with a lot of 2D part drawings.

Why isn’t this on by default?

(Pascal Golay) #8

Hi Andy - it was - double-click, that is, and this could all be on by default -I think that would be fine. I don’t think there was a setting for double click - it just worked but with the new single-click behavior I think Mikko felt there needed to be a setting to be able to turn it off, and it seemed reasonable to control both with that setting, at least for now until we see how it plays…

It seems like it should be on by default so that we can get some field testing going.

Does this work with regular polygon edges? So I can click to select edge, double-click to select loop of edges?

[/quote]On a polygon the control polygon lies on the edges. When the points of a polygon are on and you single-click on an edge the selection menu pops up because you are selecting both the edge and the control polygon. This makes double-clicking on an edge impossible but also makes it harder to select the object.

On curves this feature makes sense. On (poly-) lines not.


I love it! Before I actually make surfaces I work a lot just with lines and curves. I was turning ControlPoints ON/OFF all the time. This new feature is a big improvement for my workflow. Thanks!

Nice work Mikko! I vote for having it on by default as well but keep the option to disable it.

I know we’re not there yet with mesh modeling for sub-d workflows but this will be a must have for row and column selections on meshes as well.


This IS a useful addition to the toolset! I anticipate this will become a solid part of my working process.
