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

### **Steps**

1. Select curves that form a frame.

   Overlapped segments result in a single pipe segment.
2. Enter the radius.
3. Specify the Cap and Struts options.

   0 is suggested when the input curves are not linear.

#### **Struts**

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