Design-Set Fb

See Modelling FB toolbar > Add Design-Set


Use a Design-Set to bring together a number of dimension and parameters into one dialog.

We add to the Design-Set those dimensions and parameters that we believe to be important to the outcome of a design-objective.

You can add more than one Design-Set to the model.

Why use a Design-Set

Questions: "Why use a Design-Set when we can use the Part-Editor to edit dimensions of different Parts, and also use dialog-boxes to edit the parameters of different elements?"

Answer: "We can edit ONE Design-Set to edit MANY dimensions and parameters". This has many advantages. For example:

We can give the model to a different design engineer, and say "Open the Design-Set, edit dimensions X, Y, and Z, then edit parameters A, B, and C".


Rename each dimension to a 'functional name'. This will help you recognize the dimension in the Design-Set.


After you add a dimension to a Design-Set, you CAN ONLY use the Design-Set to edit that dimension.

To edit a dimension in the Part-Editor again, you must delete the dimension from the Design-Set.

A dimension that is in the Design-Set is grey in the Part-Editor.

When you open the Design-Set dialog-box, the toolbar is locked. It is NOT active.

To unlock the toolbar:

1.Click the Padlock iconRed-14-3.

The other icons in the toolbar become 'colourized' , and 'active'.

The Design-Set toolbar icons are:

Red-14-1 : Add element-row

Red-14-2 : Delete element-row

Red-14-3 : Padlock icon

Red-14-4 : Rebuild icon

Red-14-5 : Ok-Bar-16 OK, Close, Undo Edits, Help

Design-Set - 2 Element Rows

Design-Set - 2 Element Rows

To add Element-Rows

1.If necessary, click the PadlockRed-14-3 to colourize the toolbar.
2.Click Add Element-RowRed-14-1 one time for each dimension or parameter you want to edit with the Design-Set.

In the image above, there are two Element-RowsRed-14-6Red-14-7.

3.There is a PadlockRed-14-8 associated with each Element-Row.

One Element Row is always the Active Element-Row.

The Active Element-rowRed-14-6 has an Orange Property Value label and a white-box

To make an Element RowRed-14-7 the Active Element-Row:

1.Click in the Select in graphics label

To delete an Element-Row

1.Click the Select in Graphics label for the Element-Row you want to delete -  it should now be the Active Element-Row
2.Click the DeleteRed-14-2 icon

tog_minusLink a Dimension to an 'Element-Row'

1.If necessary, open the Design-Set dialog-box
2.Edit a Part with the Part-Editor
3.Click the Select in graphics label Element-Row, so that the  Property Value  becomes the Active Element-Row.
4.Click the dimension arrowhead in the Part-Editor

The Dimension nameRed-14-1 replaces the Select in graphics

The Dimension valueRed-14-2 replaces the  Property Value  label

The Locked PadlockRed-14-3 becomes colourized. In this state, you cannot overwrite this Element-Row

The next Element-Row becomes the Active Element-Row.


Maximum and Minimum 'Hard-Limits'

It is frequently useful to set a maximum and minimum limit for each dimension or parameter in the Design-Set.

To set the Maximum and Minimum Limits

1.Click the up/down arrow buttonRed-14-4.

The Minimum and Maximum data-boxes becomes active.

2.Edit the Minimum value and Maximum values.
3.Edit the Dimension as required.

1.Continue to add Element-Rows  different dimensions to link those dimension to different element-rows.
2.Continue to select those dimensions you believe will improve a design objective.

tog_minusLink a Parameter to an Element-Row

In addition to dimensions, you can link Parameters in dialog-boxes for different element types. For example: Parameters for FBs, Parameters for a Gear-Pair, Parameters for a CAD-Lines, and more.

To link a parameter to an element-row [or replace an existing dimension or parameter]

1.Open the Design-Set dialog-box
2.Click the element-row to make it active
3.Click the Padlock icon, to unlock the Design-Set.
4.Click the element-type in the graphic-area or the Assembly-Tree to open its parameters list box - for example a Function-Block

A pop-up dialog opens with the parameters that are available for the element-type . The names of the parameters are in CamelCase. - see below: 'Parameter Lists in different-elements' below.

Generally: If you cannot identify the parameter's name, then do not use it - see Parameter tables below for each element-type.

5.Click the parameter in the list you want to link to the Element-Row
6.Click the OK-tiny-13-17 button to close the parameter list box

The parameter name, and its value shows in the boxes of the element-row.


7.Click a new Element-Row and make sure it is the active element-row.

Note: the active element-row may automatically become the element-row that is above or below.

8.Continue to click different dimensions or parameters to link those to different element-rows.
9.Click the Padlock again to lock the Design-Set
