Opening fan door animation - pivot points

office6PUWT — Mon, 19 Apr 2021 13:24:15 GMT

To create an animation of this door opening I need to rotate each of these 12 fan blades from (-55 degs (1st blade) in increments of 5 degs each up to 0 deg (12th blade)) around their own individual pivot points located at 12 different points along a central axis running through the centre of all of the bottom holes. How do I do this please?

all best

Hello @office6PUWT ,

I don't see anything in that image (invalid file), but the array tool seems like a likely candidate.

Best Regards,

Like Alfred says, the Array Tool is probably going to be helpful for you. Sometimes there is no "automatic" way to do what you want. You may just need to animate them one at a time until it works like you want it to. Often, simple sounding animations can be quite time consuming to get set up properly. It looks like (I was able to see the image) you already have them rotated by 5° each and that you've mostly solved it.

Post the file and the desired before and after picture would help to understand what you want to do.

If I understand your goal correctly you could use a wire parameter. I assume you want to rotate the top blade (#1) from -55 to 0 about it x axis and have the other blades follow such that they all wind up at 0 degree. Wire the x rotation of #2 to #1 so that its angle is 11/12 of blade #1's rotation. #3 would be 10/12 of #1, etc.
