SPI Ducting for Inventor Technical

A straight pipe is defined by its diameter, height, thickness and the welding gap.









 

A chamfered pipe is defined by its diameter, height, thickness, welding gap and - optionally - top- and bottom base rotation angles, in X- and Y-direction.
 

A cone is defined by a bottom base diameter  top base diameter and height. The offset parameters X and Y define the distance between the displaced center of top base and the center of bottom base, both can be positive or negative.
 

An elbow consists of (at least three) pipe segments. The elbow is defined by its diameter, angle, radius, thickness, welding gap and offsets of straight pipe at the start and end segment.
 

The 3 segmental elbow. Defining parameters: diameter, angle, radius, thickness, welding gap and offsets of straight pipe at the start and end segment.

With Version 7 welding gaps can appear on the inner and outer side.









The classical 3 sided Y-transition. Diameter, length, 2. diameter, 2. length, welding gap, radius are the defining parameters.
 

A T-Connector  connects two pipes with equal diameters. The connecting height H defines the position, where the side pipe starts. The angle A of the side pipe to the center axis may differ from 90 degrees.
 

An asymmetrical T-Connector connects two pipes with different diameters. The side pipe may have a different diameter and may have an offset to the center axis. The main pipe may be a cone with different bottom and top diameters.
 

Another transition  may occur between a (filleted) rectangle and a circle. The center of the top base (circle) can be displaced from the center of the bottom base (rectangle), either in X- or in Y-direction.

A symmetrical Y-Transition, is a transition between a circle and two circles with equal shapes
 

An asymmetrical Y-Transition is a transition between a circle and two circles with different shapes, heights and offsets.
 

A rectangular pipe is defined by hight, length, width, radius and welding gap. 

A rectangular cone is defined by hight, length, width (bottom and top), offset, radius and welding gap.

A rectangular flange  is defined by length, height, width and thickness. The holes can by specified by the hole diameter, the amount in X and Y direction and an offset from the border in X and Y direction too.

The selection dialogue shows the entire component types in different categories (Connectors, Flange, Standard, Transitions).

At first select a category (e.g. Standard) and then select a type (e.g. Elbow).

When you give <OK> a new window is displayed where you may define the corresponding driving parameters (e.g. angle etc.).

As soon as you have defined the dimensions to your needs the 3D model is created (you will be able to modify parameters afterwards). With a single step, the unfolding is automatically generated from the 3D model. Special parameters from the materials database are considered during the unfold phase.

SPI allows the exact positioning of all elements and dramatically simplifies the placing of models on existing ones. Of course you may insert several instances of the same component into an assembly.

The SPI SheetMetal Inventor Suite is available for current releases of the Autodesk Inventor Suite.
