SubD Tools



The MultiPipe command creates a SubD pipe frame with smooth conjunctions from intersected curves.


  1. Select curves that form a frame.

    Overlapped segments result in a single pipe segment.

  2. Enter the radius.

  3. Specify if pipe openings will be capped.

  4. Enter a number for strut divisions.

    0 is suggested when the input curves are not linear.

Command-line options


The approximate radius of the SubD pipe frame.


Cap (On/Off)

On adds a face at each opening. Off does not.


Strut divisions

Lines are divided at intersections into "struts", and then the SubD pipe frame is created with the specified divisions on each strut.


3 lines are divided into 7 struts with 3 divisions on each of them.
