Hi Andrei,

> 1. Update automaticly when chage radius?

I just did a quick test and it seems to do that already over here... Which exact version of pipe are you using, can you post it here?


> 2. To produce not only circle tubes but also rectangular, where you can set edge measure and fillet raiuds?

You can just use the regular Sweep command to make a rectangular tube, draw a rectangle a little off to the side (outside of the bounding box of the curve), so that you'll get "auto place" mode activated for the sweep. Then just select the rectangle and run Construct > Sweep and you'll have a rectangular tube right there...
