[W.I.P.] Curve Tools plugin

[micheus]

Hi guys. Long time without an update.
Now v2.2.7 is out I have some time to get back to work on this tool.

This update must bring a little more stability and add two new features: Bevel for linear curve with the option to segment it and Snap mode (On/Off) which allow us to add a control vertex over a Wings3D object surface.

The options in use on Geometry for Curve Tools:


The sweep object converted into mesh and worked in Geometry with Extrude and Inset to create the curve piece details:

I remembered the situation at that time.

How to reproduce.
Create a curve.
The situation where the Tweak option does not select anything.
Hold down the F1 key at first. (A 'X' character bold in Infomation verbose)
And ...Dragging curve a point or a segment while [F1] key Pressed.

Yes,This is not a formal Wings3D keystroke.
But I was inadvertently doing this mistake of keystroke Blush
There was also reproducibility.

Sorry tkbd. I was reviewing the posts and noticed I forget to dig in this critical bug.
It's fixed now.

Here is the update

Code:

- Added snapping option to curve edition. This means the control vertex of a curve can now be snapped on a Wings3D object's face;
- Added Bevel command for linear curve style;

- Workaround in Sweep to fix some edge loops being wrongly rotated by 180°;

- Fixed the Tweak constraint keys not working;
- Fixed the envelop modifier for objects which had its curve rotate or scale reset;
- Fixed a bad shape rotation on line corners (scaling);
- Fixed close/open command for single edge curve;
- Fixed a hard crash by keeping pressed Tweak constrain keys and click a vertex/edge. Thanks tkbd.
