How can I implement this model? Give me some ideas, this is an incremental rotation model after an array

like this   ，As shown in the figure, how should I implement this model?As shown in the figure, how should I implement this model? Each rectangle is rotated by a certain fixed angle from the previous one

A few ways to do it....

Spiral Pattern - you need an Addin - Script.  

Search here for Translate with Rotation, the Addin was updated recently.

If not, Sweep with a Twist,  then 

Extrude > Intersect, an appropriate profile/s

Perspective view???  Might have to be a Loft, if not a twisted rectangle base model.

Might help....

There are several ways to do this. One is to loft between the ends with guide rails, then use a split body command to remove the negative areas. Note: A single sketch with a rectangular pattern of a line will give you the split paths.  Another is to create a helix in the surface workspace, circular pattern it with 4 instances, make it solid, then split as above.  Yet another would be to use the previous helix to split a rectangular block, then circular pattern that feature.
