SPI Ducting for AutoCAD Technical

Elbows are defined by, diameter, radius and angle of elbow, horizontal and vertical distance of the ends and number of segments.
 

Cones are defined by upper and bottom diameter and the length. The program allows a displacement in x- and y-axis. The number of segments (bending lines) can also be defined.
 

A transition circle -rectangle, the classic case of use is the suction hood, is defined by diameter, dimensions of the rectangel and height. The program allows a displacement in x- and y-axis. Bending radii and the number of segments (bending lines) can also be defined.  The number of welding gaps and the resulting sections can be defined between 1 and 4. 

Y-pipes with parallel exits and Y-transition with parallel extended ducting are defined by diameter (top diameter), height, distance of the parallel pipes and then number of segments.

The Y-connection  is defined by diameter, angle and length of the different parts of the pipe. The program provides T-connections  with equal or different diameter. The definition of the position and the angle of the departing pipe to the main pipe are possible.
 

Round flanges are defined by inner and outer diameter, thickness, dia­­meter of the bolthole cir­cle and the number and diameter of the holes. Rectangular flanges are defined by side length, width of flange and thickness. The func­tion allows the exact posi­ti­on of every element and drama­tically simplifies the placing of mo­dels on existing ones. Work­planes are automatically set according to the selected plane on the model. With this capability, a de­signer can build complete 3D assemblies.
