Rotational pattern with rotation of objects

[LennartM]

I am trying to create a circular pattern of square holes. These square holes are however rotated each step.  The square moves over a circle with at each 6.34 degrees a square. And the square rotates on it set centre. This is the double rotation 2*6.34 degrees.  As the rotation is double of the step on circle it is not pattern-able. What would be an alternative way to automate it?  I could create a excel sheet with points. But then I still have to draw a lot of squares..

The pattern in the picture is still in complete, it is now until 37,89 degrees but it should go to 360 degrees..

Squares with rotation

It looks to me like the square rotates a full 180 degrees per quarter circle. If so, I guess a circular pattern of four for all squares would suffice. If the rotation is not an exact 180 degrees the fastest solution I can think of it to make as many polygons as needed to achieve a symmetrical rotation, and then circular pattern each of those polygons for an adequate amount.

If I understand correctly, you want the square to rotate around the curve evenly.

First thing I notice is your angle dimensions are going to the square edge instead of to the center.

Take a look at this link.

See if this link speaks to what you are some what trying to do.

Hi! I don't think there is a straight forward solution. The issue here is that the rotation of the occurrence depends on the occurrence's location also. This means the pattern cannot be totally defined by the source and pre-defined parameters.

Many thanks!
