Additional Tools : Steelwork : Create Category for Fitting

Using the Steelwork mode of PARAGON it is possible to create a structural fitting such as a Lifting Lug using data sets and design parameters.

A Fitting Category must reside below a STSE which in turn must reside below a CATA element.

Select Create > Catalogue to display the Create Catalogue window. Refer to Create Catalogue for further information. Create a new Steelwork Catalogue in the database hierarchy with the purpose set to STL.

Select Create > Section to display the Create Structural Section window. Refer to Create Section. Create a new Steelwork Section in the database hierarchy with the purpose set to STL.

Select Create > Category > for Fittings to display the Create Structural Category window.. The Create Structural Category window is similar in layout to a standard Create Category, but contains additional sub windows specific to Steelwork Fittings.

Referring to Parameter Definitions populate the window with a set of data as follows:

Make sure that the values are also populated.

Referring to Create Geometry select Geometry Ref in the Model References part of the window.

Click Geometry Ref in the Model References part of the window to display the Geometry References sub window.

Initially the Geometry References sub window will appear unpopulated.

Create a New SBOX element by selecting SBOX in the Positive pulldown and populate the remainder of the window as illustrated below.

Click Data Ref in the Model References part of the window to display the Data References sub window.

Create the first data element by clicking NEW and declare this as a Design Parameter as below.

Create three additional Data References with the Definition set to Expression and values as follows:


Description	Key	Expression
Height of Hole From Base	LHEI	100
Lug Radius	LRAD	40
Hole Diameter	LHOL	50

The populated window should appear as follows:

Click Geometry Ref in the Model References part of the window to display the Geometry References sub window.

Select SEXT from the Positive pulldown to create a new Structural Extrusion.

Populate the window as below.

Click Modify Points to display the Modify Points sub window.

Click NEW to add a new point.

Enter values into the columns of the newly created point.

Highlight a row and click Copy to duplicate the point.

Create a set of Lug Profile points as below:

Referring to Create P-Points select PPoint Ref in the Model References part of the window.

Select Cartesian P-Point (PTCA) then populate the window as below:

Click Geometry Ref in the Model References part of the window to display the Geometry References sub window.

Click the SEXT element in the list of Geometry References

Select NLCY from the pulldown list of Negative geometry.

Populate the NLCY element with the following values:

Once the window has been populated open the Representation window:

Click Holes Drawn to display the NLCY as a hole in the Structural Extrusion.

To improve the rendering level of the curve on the lug specify a numeric value of 1-10 in the Arc Tolerance field. The value of 1 provides the best visual quality and a value of 10 being the most optimised for speed.

At this point a Part Family and Table Group can be created from the Category, then selected from MODEL.
