Use the Extension 
To download and install the extension follow the steps on the Sketchup page. To open the Loop/Ring Parameters click Extensions and Draw Ring. 



The ring has a diameter which is twice the radius. It has an integer number of loops so that the start and the end meet seamlessly. The basic cross section is a rectangle, which may be smoothed to an ellipse (circle if width = thickness). It has two levels of rotation, one around its own center and one around an external point. 

Strip width 
Cross section in the x direction 


Strip thickness 
Cross section in the y direction 

Offset x 
From the outer twist rotation point 

Offset y 
From the outer twist rotation point 

Radius 
Ring radius 

Loops 
Must be an integer to close the ring 

Inner twists 
Number of inner rotations of the strip 

Outer twists 
Number of outer rotations of the strip 

Strip type 
Rectangular or elliptical 

Detail 
The number of polygons are multiplied by 4 when the level of detail is increased one step 

Strip color 
Color applied to all polygons 

Edges 
Soft smoothes all, hard shows all edges. 

Notes 
If your design has multiple loops then start producing a ring with Detail set to Coarse. Increase the level of detail when the overall design looks fine. The inner rotation is 0.5 for the classical MÃ¶bius strip. It may also be any multiple of 0.25 for a quadratic cross section. 

Method 
The creation process involves the following steps for each segment of the ring:
