[Hex 1.x] Use Dynamical Extrusion and Path - Polyloop

In this video, you will discover how to change the patch of an extrusion dynamically, and change the radius on the control vertices.

Switch to Full DG (In the Dynamic Geometry Panel.

Select the faces to extrude.

Pick the Sweep tool: the extrusion begins. For each click, you add a new section. With the right click, you can change the radius of the next section.

Validate with enter when done.

In the DG panel, you must have a "parent" and two "children". The parent is the result of the two childrend. One child is the original shape (the polygonal face) and the other is the patch of the extrusion, or named Control Curve.

Picking one of the children select it in the scene.

For a better display (the control curve is inside the model), switch to transparency mode (on the bottom right of the control panel).

As you can notice, a kind of red line with a small square appears on the control curve of the patch.

In the Utility panel, take the Stretch tool: if your DG level was on the result (parent), it switchs to children selection.

Click near a vertex of the control curve, you can move it, and it change the patch of the extrusion - or ../..

../.. Click on an edge, it will move it too - or ../..

Click on the red manipulator, it will change the radius of the current section. Take care, the responsiveness is important!

If you select the child which is the original shape and move the vertices/edges, it will propagate along the extrusion.

Extra steps:

If you select an edge of the control curve, you can add another control vertex with the Tesselate line tool (X shortcut)
If you want to tweak the result, and not anymore the control curve/shape, you must collapse the DG, by clicking on the small lighting icon on the left of the level in the DG panel (the on -under- the smoothing if you have one, or it will also collapse the smoothing)

Thomas nothing shows up with the "attached images". Are we to be helped with a hex file to work on?

The attachement image is only for the thumbnail for the Tutorial forum itself.

Still would like a Hex file to work on if possible please Thomas.

only create a 3x3 grid as a basis for the tutorial and it will work the same

I just updated the video link, it now works!
