Grid extrude with twist.

charles_mcneice_ii

I created a loft with a twist in my drawing. The grid extrude ignores the twist. How do I resolve the issue? Thanks for looking!

@charles_mcneice_ii I used a bridging curve just to get the centerline for the sweep operation. To get the angle to match your example I just measured the angle between the top and bottom profiles you already had and manually input it as the twist dimension in Tweep.

I made the document public so you can copy it. You should be able to grab the custom feature from it linked through the doc, or you can get it at the forum thread here.

It is a grid extrude feature, not a grid loft feature. So it is only going to extrude the original shape in a direction without twists or morphing shape.

What is your end goal?

• Are you wanting the exact same grid, just with a twist?
• Or are you wanting all the hexagons to loft from the larger hexagon to the smaller hexagon?

Hi Michael,

I want the grid with a twist so it will spin. This will eventually be what I call a flying machine powered by an Estes D12 motor. Similar to below.

This is my channel with 3d printed fling machines:

As I always say, when in doubt, tweep it out.

I want the same grid with a twist.

The drawing will end up as what I call a "Flying Machine." An Estes D12 rocket motor will power it.

My original post seemed to vanish, so sorry if this is a duplicate.

Yes, that's it!!

Please, tell me how it was done, or what makes it work. The document is read-only.

Thanks!!!

I can see from the example that a bridging curve was used. It does not connect any points or bridge anything, so I am a bit lost here.

After some searching, I see that Tweep (twisted sweep) is a custom script. I can't see the settings because the document is read-only.

Thanks, Derek, for your help with this project! Is there any way to offer a tip for your assistance?

@charles_mcneice_ii I do stuff like this for the love of the game, just give me a shoutout in the video when you post it. I wanna see how these fly.
