Modeling FB | Add Pattern FB

What is the Pattern tool?

A Pattern FB makes an array of one or more Solids.

A Pattern is similar to a circular or linear array as found in your CAD.

However, the Pattern FB must anticipate the motion of each Solid in the array at each instant in a machine-cycle relative to the other Parts in the model


When you use Pattern FB to hide a copy of a Solid at phases in the machine-cycle, you also remove its Mass-Properties.

Add Pattern FB

Add Pattern FB

Modeling FB toolbar > Pattern FB

Menu :

Add menu > Add Pattern FB

What to do :

STEP 1.Add the Pattern FB to the graphic-area

1.Click Modeling FB toolbar > Add Pattern FB

2.Click again in the graphic-area

The Pattern FB is now in the graphic-area and the Assembly-Tree.

How to Edit :

STEP 2.Open the Pattern dialog-box

1.Double-click a Pattern FB in the graphic-area

or

See How to Open a Dialog-Box.

The Pattern dialog-box is now open.


STEP 3.See Pattern dialog-box

Preparation :

Add Solid elements to the model. The Pattern FB can make a pattern of Solid elements

Use Visibility toolbar > Show Solids in Mechanisms to see the Pattern of the Solids

Notes :

A simple application of the Pattern element is to show or hide a single Solid at different machine angles in the machine-cycle.

Note: Pattern FB and a Driving Pulley:

If you want to make a Pattern of a Solid element along the complete belt-length, you must make changes to the timing of the Pulley.

1.Add a Gearing FB to the input-connector of the Motion-Dimension FB that is driving the Pulley

2.Open the Gearing FB dialog-box

3.Make the Gearing Ratio = Belt-Length / Pulley-Circumference.

The Pattern of the Solid elements should now be at equal spaces along the complete Belt-Length.
