SPI SheetMetal for AutoCAD Technical

SPI SheetMetal AutoCAD® brings sheet metal manufacturing knowledge up front into the design process, introducing dramatic productivity gains and cost savings in the design and manufacture of sheet metal parts. This is achieved through a unique combination of specialized sheet metal design capabilities. SPI leads to significant increase in ready-to-manufacture products and makes the design process instant, resulting in drastic time savings between conceptualization and the testing of actual parts. After all SPI drastically decreases the time-to-market.

Unique combination of sheet metal design capqabilities

 

SPI SheetMetal AutoCAD brings sheet metal manufacturing knowledge up front into the design process, introducing dramatic productivity gains and cost sa­vings in the design and manu­facture of sheet metal parts. This is achieved through an unique combination of specialized sheet metal design capabilities. SPI SheetMetal is 100 % inte­grated with AutoCAD and allows multi-document-sessions.
 

Solid design

Creation of a sheet solid is easily done. SPI creates 3D solids from arbitrary 2D contours, among others from profiles that you can create using "sweep along path". The selected type of material and the thickness will control the design to create a part ready for manufacture. During the design process, the designer can easily change the type of material.
 

Modify flange

As every other command modifications are done fast controlled by ease-to-use panels where one defines length, width, offset, bend radius, and bend relief.
 
 

Joggle

SPI SheetMetal AutoCAD provides a joggle command.
 

Sharp cornered construction

The option sharp cornered speeds up design when it is not necessary to display fillets.

Bending

The designer can re-bend the flat sheet. This allows the creation of 3D solids from existing unfoldings. The bend line table provides an editable list with information that helps to define the follow up of the forming process.
   

Sheet metal shelling

With sheet metal shelling thin sheet metal shells are produced fast and precisely from solids. The split attributes guarantee an accurate unfolding result. In that way you create complex sheetmetal designs with an enormous speed.
 

Split corner

The split command allows for precise unfolding of closed boxes. The designer does not need to de­­sign slots but just adds split attri­butes to the corner areas.
   

Tool Management

Based on partnerships with leading tool manufacturers, SPI offers a wide range of the most frequently used punch and emboss tools (e.g. circle, oblong, rectangle, hexagon, dimples, louvers, bridges etc.). Several pre-defined dimensions of tools are available.
 

Manufacturing costs

Estimated manufacturing costs are calculated simultaneously during the design process based on: type and thickness of material, number of bends, number of  punch and stamp tools, length of contour.
 

Split corner

The split command allows for precise unfolding of closed boxes. The designer does not need to design slots but just adds split attributes to the corner areas.
   

Flat pattern (unfold)

Material definitions and bend compensation factors drive the unfolding process. They are easily put into the technology driven material management, which calculates the precise flat geometry according to the needs of the designer. He can edit correction factor and discrete shortening values and formula calculations influenced by type and thickness of material, type of manufacturing process, bend angle and bend radius. At the prototyping or pre-production stage, SPI's 'one-click' solid model unfolding - in just seconds - leaves a flat pattern transferable to laser or punch CAM programs and pressbrake control systems. The designer can start the unfold command at any time to control the design process. During the unfold calculation the part is analyzed. Any problem area is displayed and reported. Common problems detected include: overlapping of material (clash detection), bend radius lower than critical minimum (break).

Standard views, isometric views and explosion drawings are created. The program offers automatic dimensioning and automatic update of the shape when the solid is modified.
