How to make an elastic band between 3 hubs in LDCAD?

 

can't round

I think you must add a fourth path point with the same diameter as the second one) in the middle for the bottom band. Also take care of the order of path points (left, middle top, right, middle bottom)

I'm a newbie. I can’t understand how to add points. Сan't add point to bottom. Could you tell us more?

Points get added based upon the current one.

In the status bar you'll see a point number when hovering over an existing one, using that make sure you select the last one (number 4 in your latest image).

While the last point is selected press the ins key to add a new one.

Rotating the point like the second one in your image is only needed/useful when working with things like chains in order to align e.g. gear tooth's. And even then only the first one will have any effect on the generated part.

ps: make sure the editing grid is set parallel to the band's surface/point circles before you press ins.
